Having appeared since ancient times with crude and simple products, the steel industrial revolution has opened a cycle of outstanding development in the steel industry. With new roles such as helping to shape human life, participating in all current fields, and contributing to revolutionizing industries.However, not everyone knows about the development history of this industrial revolution. AG真人游戏 Steel sends you information about this revolution in the article below!The steel industrial revolution is a step in the development of human civilizationWhen did the steel industrial revolution begin?When was steel first made? Steel was first manufactured in ancient times, but in this period, the steel industry was located in places with raw materials, electricity, and running water to facilitate the production process. However, it was not until the 1850s that the history of the steel industry began to develop. In 1857, thanks to the development of the Bessemer converter by Henry Bessemer, steel was mass produced. Since then, steel has become a staple of the world's industrial economy and soon replaced iron in the construction industry.The steel industrial revolution marked a leap forward in the history of human civilization. The flexibility and sturdiness of steel today is not only used in construction but is also commonly used in many other industries.What was steel used for in the industrial revolutionThe steel industry has opened new doors for human civilization. The steel history timeline has marked the development of the world economy. With its advantages and versatility, steel is used in many different industries. Below are some applications of steel in the industrial revolution.Steel is widely used in construction architecture. After gradually changing iron in the construction process, steel seems to open a new era of skyscrapers and modern architectural works. Iconic skyscrapers represent famous architectural works today, such as the Eiffel Tower, Burj Khalifa in Dubai, Shanghai Tower in China, and Lotte World Tower in Korea. It's all a testament to the transformative power of steel in building architecture.Eiffel Tower - A famous structure made of steelSteel is used in transportation The steel industrial revolution plays a huge role in the development of transportation infrastructure. The advent of the railway industry saw a transformation with the widespread adoption of steel rails, allowing trains to travel at higher speeds and carry heavier loads. Besides, steel also contributed to the construction of iconic steel bridges, including the Brooklyn Bridge and the Golden Gate Bridge. These are two bridges that demonstrate the outstanding strength of steel in building modern transportation routes. In addition, steel in the industrial revolution was also used to build ships, cars, and aircraft.Steel and industrialization The steel industrial revolution ushered in a new civilization in human history, and steel played a central role in driving this enormous change. Steel is associated with the industrialization process as it gradually replaces iron to become the main component in the construction process. Thanks to Henry Bessemer's Bessemer converter, the history of the steel industry reached new heights by revolutionizing production processes and increasing productivity on an unprecedented scale. Steel has had a great impact on the industrialization process, contributing to promoting economic growth.Steel in daily life Steel is widely used in daily life; household appliances, furniture, tables, chairs,... all have the appearance of steel; they help our lives. We become more modern and aesthetic. Steel's ubiquity in everyday life speaks to its invaluable role in shaping modern society.Steel is used to make household appliancesChallenges and innovations in the steel industrySteel production is one of the core industries of the global economy. However, like any other industry, the steel industry is facing challenges and innovations in steel production.Fluctuating market conditions In fact, the steel industry has passed through the development stage and is in a period of saturation when facing volatile market conditions. In the context of inflation and the global economic recession, steel prices continuously decrease, which reflects the difficult reality of the production and business of steel industry enterprises.Climate changeClimate change is one of the biggest challenges today. The steel industrial revolution led to mass production of steel, which in turn uses a lot of energy and produces large amounts of emissions. Reducing emissions and saving energy is one of the important requirements for this industry. This also requires steel manufacturing businesses to find ways to reduce emissions and increase sustainability in the production process.New technology When technology continuously changes and develops, it directly affects the steel production industry. This forces steel manufacturing businesses to keep up with new technology to improve product quality. However, along with new technology comes the cost of investing in production lines, which is also a big barrier for steel manufacturers.Future direction of the steel industryThe steel industrial revolution has brought the steel industry to develop dramatically, becoming a key sector of the world economy. Looking at the current situation of the iron ore market and steel industry, one of the future directions that the steel industry wants to aim for is the development of the green steel industry. When governments around the world introduce many new regulations as well as carbon taxes to improve the environment, green steel production is a goal that is both vital to the steel industry and contributes to limiting warming.Currently, many of the world's leading steel manufacturers have started producing green steel or have set goals in the next few decades to no longer use fossil fuels. Vietnam's steel industry also aims to be carbon-neutral by 2050. Green steel is not only a trend but also a necessary step to protect the environment and create a sustainable steel industry in the future.Green steel production is gradually becoming a trend in the futureAG真人游戏 Steel - The future of Vietnam's steel industryIn recent years, Vietnam has grown to become one of the world's major crude steel production powers.

The importance and significance of steel in today's world cannot be denied. Steel is considered the spine of a modern, civilized, and progressive society. But when was steel invented? How is the development process?In the article below, AG真人游戏 Steel will help you learn about the history of the formation and development of the steel industry.When was steel invented? Let's find out belowWhen was steel invented?It is difficult to have an exact answer to the question 鈥淲hen was steel invented?鈥� Many people think steel appeared at the beginning of the industrial revolution, but it appeared a long time ago. After the Iron Age, from the 13th century BC, steel was invented by heating iron in a hot fire, at which point the iron would become harder and stronger. Since then, people have found traces of steel in many different cultures and territories around the world, and usually only a few shapes of steel are made for use in everyday life.However, the early invention of steel had a wide range of carbon in the metal, from less than 0.1% (low carbon steel) to 1% (high carbon steel), which could lead to steel with a higher carbon content being very brittle. This brittleness can be reduced by tempering the steel, which is a form of heat treatment that was used in Egypt as early as 900 BC.Later, in the mid-1850s, Henry Bessemer, the British inventor first created a method to produce steel in large quantities. Since then, steel has been produced based on the Bessemer process. The operating principle of this process is to heat iron ore and other chemicals, then blow oxygen into the blast furnace to separate impurities from the metal mixture. This method is similar to the steel production method we are using today.Bessemer steel making processUntil now, the creation of steel was essential to human life. Steel is always ahead of the game and is commonly used in construction and many different industries. There are a number of reasons for this, from the variety of shapes it can be formed into to its relatively low strength and weight compared to other metals.Development stages of the steel industryTo continue answering the question, when was steel invented? What is the development history of steel? Let's study the development stages of the steel industry below.Early stageThe steel industry began to form in the late 19th century under the leadership of two leading developed countries, China and India. During this period, the steel industry was often produced manually, by forging or hand casting. This is the initial stage of the steel industry, when production methods have not been automated and the production scale is still small.In 1856, the birth of the Bessemer furnace helped steel production happen faster with cheap costs and large output. By 1865, Andrew Carnegie brought the Bessemer process to America, and from then on, America suddenly rose to the top of the steel industry.Historical period that saw a rise in steel makingAfter its infancy, the steel industry experienced a period of strong growth. During this period, steel production technology was improved, production processes were automated, and production scale increased. This leads to increased productivity, reduced production costs, and increased competitiveness in the steel industry. This is also considered a historical period that witnessed an increase in steel making.Steelmaking by BOF blast furnaceAt the beginning of the 20th century (1970s), many wars occurred. Leading to increased demand for steel to serve the needs of manufacturing and producing weapons and tanks. Western countries entered the stage of industrialization and modernization. Since then, the demand for steel has increased dramatically to serve the construction of infrastructure projects and buildings. From here, the appearance of "Oxygen Blowing Furnace (BOF)" and "Electrical Arc (EAF)" technology has created a major turning point for the development of the steel industry.Saturation phaseAfter going through a historical period that witnessed an increase in steelmaking, the steel industry entered a period of saturation (from the 1980s until now). During this period, the steel industry was able to balance supply and demand, and the growth rate gradually slowed down. Businesses in the industry are forced to expand their markets and seek new development opportunities to ensure continued growth and competition. However, the history of steel is still in the development stage, and we are aiming for more sustainable goals in the future.China currently dominates the global steel industryThe role of steel in today's lifeIt can be said that there is no field that does not use steel; steel is present almost everywhere. With the invention of steel and its durable and flexible properties, steel is known as an extremely important source of raw materials and is widely used in life, especially in the construction field. Below, let's learn about some of the roles of steel in today's life.The role of steel in constructionWith tough properties and the ability to be easily shaped at high temperatures. Steel invented has replaced iron, making it an indispensable material in the construction industry to increase the solidity and durability of projects. An important application of steel in construction is to use it to make reinforced concrete and house foundations, bringing stability to each project. In addition, steel is also used to build infrastructure, roads, public works, and transportation to serve the needs of the community. And until today's rapid development, there is still no material that can replace steel.The role of steel in everyday lifeBesides being an important element in construction, steel is also used in everyday life. From household products such as kitchen utensils and thermos bottles to interior decoration equipment such as tables, chairs, stairs,...

Carbon steel is steel made of iron and carbon with some other ingredients such as manganese, silicon, phosphorus,... Let's delve deeper into the characteristics, applications, and important aspects of this type of steel with AG真人游戏 Steel.Carbon steel is among the top 4 most popular types of steel, used in many fields such as industry, manufacturing, civil use,... because of its flexibility and hardness.The more carbon in the steel, the higher the hardness and durability of the steel, in which carbon steel components can contain up to 2.1 wt.% carbon. The relatively low production cost of carbon steel makes it more preferred over other types of steel. Below, AG真人游戏 Steel will explore with you the pros and corn, production methods and applications of carbon steel.Carbon steel is steel made of carbon along with other elementsWhat are the different types of carbon steel?Carbon steel is categorized into three types based on its carbon content:Low carbon steelLow carbon steel has a carbon ratio of 0.04 - 0.25% or 0.29% with small amounts of other elements. Therefore, steel has low hardness and durability, so it is also called mild steel. However, they exhibit good ductility and can be easily shaped by pressing or bending, even when cold-formed.Medium carbon steelMedium carbon steels with average carbon content (0.25 - 0.5%), providing good corrosion resistance and high durability. Medium carbon steel has good heat treatment and cutting performance but poor welding performance, requiring preheating in welding. This type of steel is mainly used in high-strength moving parts such as air compressors, pump pistons, turbine blades, gears, crankshafts, rollers,...High carbon steelThanks to the carbon content of 0.6 - 2%, high carbon steel has good bearing capacity and high durability. The hardness of this steel can be up to 60 - 65 HRC according to Rockwell C. High carbon steel is mainly used in the production of springs, wear parts and high-hardness tools.Each type of carbon steel exhibits unique properties and applicationsWhat is carbon steel made ofCarbon steel is primarily made up of iron and carbon, combined with a number of other ingredients such as manganese, silicon, phosphorus,... In which, the carbon content determines the mechanical properties and durability of the steel. If the amount of carbon is low, the plasticity is high, convenient for shaping, bending and vice versa. However, the hardness and brittleness of the product depends on the metallurgy and heat treatment process. The carbon ratio can range from 0.02 - 2.1% depending on the amount of steel but the common ratio is 0.1 - 0.3%.Pros and cons of carbon steelAdvantagesEach carbon steel type has unique mechanical properties when undergoing metallurgy and heat treatment. Manufacturers can adjust technical parameters to create outstanding advantages for carbon steels as follows:High durability and hardness: High carbon content enhances the steel's bearing capacity and resists environmental impacts.Corrosion resistance: Carbon steel has extremely good corrosion resistance, so it is often used in the chemical, petroleum and marine industries.Good bending and melting ability: The amount of carbon can be easily customized to help the steel have flexibility for shaping, which is crucial in manufacturing and construction processes.DisadvantagesCarbon steel still have some disadvantages such as:Easy to rust: Manufacturers often add about 10-12% chromium to the composition, which acts as a moisture-proof layer to help limit rust when exposed to the environment.Poor aesthetics: Carbon steel lacks the smooth, shiny surface like stainless steel. Therefore, they are often applied to products that do not require high aesthetics such as pipes, machinery, spare parts,...Carbon steel strength helps it be applied in many areas of lifeHow is carbon steel madeCarbon steel can be produced from iron ore, scrap steel or a combination of both without losing its properties and strength. By heating iron ore and coke in the absence of air at a temperature of about 1650 degrees Celsius, the molten iron is enriched in carbon from the burning coke. The remaining impurities combine with lime to form slag, which floats on the metal surface to be removed. The product initially contains approximately 4% carbon, which is then decarbonized to reduce it to the desired level. Decarbonization occurs by passing oxygen through the melt forming monoxide and carbon dioxide.Applications of carbon steelsPossessing many outstanding properties, carbon steel is a material widely used in many different industries, typically:Road and bridge construction: Carbon steel has good corrosion resistance and high durability, suitable for building infrastructure such as roads, bridges, buildings, tunnels,...Automobile industry: Carbon steel is an ideal material for car parts such as vehicle frames, wings, hoods, exhaust pipes,... because of its high hardness, lightness and durable structure that helps reduce weight and increase space efficiency for vehicles.Aerospace industry: With its lightweight properties and outstanding mechanical strength, carbon steel is used in the production of aircraft components, spacecraft bodies and rockets.Oil and gas industry: Carbon steels are used to produce equipment and oil pipes thanks to its good bearing capacity. This will ensure the safety and performance of pipeline systems under the harsh conditions of the oil and gas industry.Manufacturing and machinery industry: Carbon steel has ductility and flexible shaping, so it is suitable for processing and producing machine parts such as shafts, bearings, gears,...Carbon steel's resilience makes it ideal for infrastructure, vehicles, and machineryImport the best quality Vietnamese carbon steel at AG真人游戏 SteelAccording to Worldsteel, Vietnam ranked 12th in the world in crude steel output with 19 million tons in 2023 and belongs to the group of steel exporting countries with a turnover of over 10 billion USD.

Join AG真人游戏 Steel to learn more about this type of steel in the article below!Image of alloy steelWhat is alloy steel?Is steel an alloy? Yes, steel is an alloy made mainly of iron and carbon and mixed with other chemical elements such as copper, manganese, nickel,... Alloy steel has a total amount of these elements added that ranges from 1.0% to 50% of the total mass of the steel mixture. The added elements help improve the quality of finished steel products, increasing the steel's resistance to oxidation, elasticity, ductility, and durability.Currently, the main types of alloy steel are low alloy steel, medium alloy steel, and high alloy steel. Depending on the needs and purposes of use, consumers choose the appropriate type of steel.Alloy steel compositionNormally, alloy steel will have a few main elements; however, those elements will be mixed in different concentrations to create different types of alloy steel suitable for the intended use. It is thanks to those alloying elements that alloy steel in general has superior advantages compared to other types of steel. Below is the basic alloy steel composition used in the production.ManganeseManganese is an important alloy steel composition in the production of steel and steel alloys. Manganese is used to increase the hardness, durability, and corrosion resistance of steel. Steel with a high manganese content is commonly used in construction, automobiles, railways, and many other industrial applications.Inconel alloy steel pipesChromium Chromium has high hardness and is considered the hardest metal today. This is also considered one of the ingredients for alloy steel production, added to help increase the hardness and corrosion resistance of steel. Chromium is also used to protect metal surfaces from corrosion by creating a coating on the surface, such as on engine parts and the surfaces of cutting tools.MolybdenumMolybdenum is an indispensable element in the production of structural steel because of its ability to resist corrosion, increase durability, hardness, resistance to deformation under high temperatures, and improve product machinability.VanadiumAn indispensable alloy steel composition, adding vanadium helps improve the flexibility, ease of bending, and elasticity of the product. Vanadium helps structural steel increase hardness, corrosion resistance, and impact resistance, making the product lighter and more durable.Characteristics of alloy steelEach type of steel will be composed of different alloy steel composition, so they have certain properties to suit their intended use. Below are the basic characteristics of alloy steel.Alloy steel is more durable than carbon steelRegarding mechanical properties, in general, this type of steel is much more durable than carbon steel. However, in terms of toughness, it is not equal.Good temperature resistance: Elements in alloy steel will reduce carbon diffusion and make martensite difficult to differentiate when tempered at temperatures higher than 2000鈩�. To achieve this, the steel must be alloyed and metallized by a number of elements with relatively high concentrations.Regarding physical and chemical properties: alloy steel is made up of different elements, thus giving the steel special properties such as anti-rust and good corrosion resistance; being highly durable; high heat resistance,...Popular steel gradesCurrently, all types of alloy steel are produced based on popular steel grades to suit the general requirements of the world steel market.

Vietnam's steel industry has made remarkable developments in both production scale and technological lines. Vietnam steel quality has gradually reached important markets such as Europe and America. Today AG真人游戏 Steel will make an overview of Vietnam quality steel as well as learn about breakthroughs in the country's steel production technology.Vietnam steel quality based on breakthroughs in steel refining technologyPreviously in Vietnam, most steel was produced through electric arc furnace (EAF) technology, but the EAF method was assessed to cause high electricity consumption. In addition, input materials such as iron ore or scrap steel contain too many impurities, which has generated more dust and large slag in the production process, reducing the furnace's life span and affecting the quality of the output steel.In the period from 2010 to 2020, many domestic steel enterprises have installed blast furnaces with large capacity, specifically Hoa Phat has operated 2 blast furnaces with the capacity is 1,350 m3, Formosa Ha Tinh has installed blast furnace No. 1 with a capacity of 4,350m3 and blast furnace No.2 with a capacity of 4,350m3. The improvement of furnace capacity has helped manufacturers minimize dust emissions, eliminate harmful impurities and reuse energy through coal gas recovery to produce thermal energy for the furnace.In addition, the large manufacturers such as Hoa Phat, Formosa or VN Steel,... have installed the technology of basic oxygen furnace (BOF) or the LD converter into manufacturing activities. In particular, the technology of BOF has a significant effect in burning all impurities in liquid iron and the steel scrap. Specifically, Hoa Phat's output steel has the percentages of impurities (Cu, Ni, Cr). ) is very low when less than 0.03% and this figure is lower than the standards of many countries in the world. Based on an extremely low impurity rate, the output steel product will achieve purity and consensus in quality, the steel will have good bending properties, combined with toughness and high yield strength will improve the sustainability of construction.Continuous investment in steel production linesDuring the past 10 years, the domestic steel manufacturers have continuously invested in steel refining technology as well as improved modern techniques in production lines in order to bring more Vietnam steel quality to the abroad markets. Currently, most steel producers in Vietnam such as Hoa Phat, Hoa Sen, Ton Dong A, Nghi Son, ... all use the most advanced steel production lines in the world such as Danieli - Tenova from Italy,  SMS from Germany,...Most of the galvanizing or color coating lines in Vietnam are equipped with gas recovery systems to help manufacturers save energy. Another highlight of these technologies from Europe is low operating costs as well as high flexibility when it can be applied to many types of steel products as well as can accept many different coating materials.For example, the CM4 color coating line of Ton Dong A is equipped with an RTO gas recovery system to help protect the environment or Hoa Sen Group's galvanizing line is equipped with an electric annealing furnace to help reduce waste of gas emissions from the factory. In addition, the color coating lines are also equipped with NOF annealing furnace technology to help the galvanized layers adhere to the steel better, assisting manufacturers to control the exact thickness of the layers, optimally treating temperature of flatness and gloss of the finished product.International standards for output productsCurrently, Vietnam steel quality products have reached many countries around the world including large markets such as Europe, America, Australia, etc. The equipping of advanced production lines has helped domestic steel manufacturers qualify to produce quality steel grades in terms of size, weight, ductility, and bearing capacity. Before being exported, steel products are fully certified standards including JIS of Japan, ASTM of America, BN of UK, AS of Australia.Besides, the quality management system standards at factories are also an important factor to evaluate the quality of output products. Most of the domestic steel factories come from corporations such as Hoa Phat, Hoa Sen, Ton Nam Kim, Ton Dong A, Vn Steel,... all obtained the certification of the latest standard ISO 9001:2015, which partly shows the production capacity and resources of the enterprise.Finding the reputable supplier of Vietnam steel qualityVietnam's steel industry in recent years has made amazing changes as it has gradually become self-production with a wide range of steel products.

Today, environmental protection is one of the main goals of all activities and businesses aiming at sustainability, stability and community value. In addition to ways such as limiting the use of plastic and not littering, recycling steel is also one of the solutions that many people trust, especially in the construction industry. In this article, AG真人游戏 Steel will analyze efforts to reduce the environmental impact of steel products throughout its life cycle of steel, from raw material exploitation to end-of-life stage.1. Recyclability of construction steelSteel is one of the most recycled materials in the world with 93% of all structural steel capable of being recycled into new products without losing its inherent properties, while only 8% of plastic is recycled. When using recycled steel, the production process can reduce electricity consumption by 80% compared to completely new production, while also reducing environmental impact and completely eliminating the exploitation of raw materials.During the life cycle of steel, materials are recycled and used in many large and small projects with the construction method of prefabricated steel frames. This is a construction solution chosen by many investors because of its outstanding advantages such as saving time, labor costs, shortening the disassembly and assembly process,...2. What is the life cycle of steel?By understanding the life cycle of steel, we can take advantage of its infinite reusability to create sustainable economic and environmental values.Collecting raw materialsFor recycled steel, you can find sources such as factories, shipyards, large construction projects, ships,... around the world. This process also includes classifying and separating scrap steel from mixed materials so that the recycling process takes place quickly, minimizing residue. Steel productionSteel factories focus on two common production processes: producing steel from iron ore in blast furnaces or from scrap in electric arc furnaces. With advanced technological improvements in production lines, CO2 emissions are reduced during the production phase.Recycling leftover productsDuring the steel production process, there will be surplus products that can be reused such as slag, iron scrap,..., which act as a substitute for some raw materials, used for the next production stages. This both reduces waste into the environment and saves significant costs and time for production processes throughout the life cycle of steel.Production of finished productsHigh-strength steel has superior properties compared to conventional steel structures because of its extremely good durability, impact resistance and corrosion resistance. Therefore, projects that require high bearing capacity such as factory frames, warehouse steel frames, cars,... often use high-strength steel to consume less material, optimize weight while still ensuring durability, safe in use.Steel recyclingFinally, steel returns to its life cycle as post-consumer scrap. At this point, it has already finished its first life cycle and is ready to be recycled to begin the life cycle of new steel.Steel is an industrial material that is recycled many times but still retains its properties, so there is no need to worry about reducing durability and safety when used for projects. Steel recycling not only contributes to reducing industrial waste in the world and protecting the environment, but is also a cost-effective solution for investors. Thus, steel scrap can be 100% recyclable and continues to exist forever throughout the life of the steel.3. Some examples of the life cycle of steelSteel is not only an environmentally friendly material but also an economical construction solution. The structures themselves can be constructed from many different types of recycled steel. Let's consider with AG真人游戏 Steel which common applications best represent the life cycle of steel.AutomobileMost of the car's structure is made from steel, so after long-term use, even though the car loses its usability, it can still be recycled. Currently, automotive steel is the largest source of recycled steel in the United States. After processing, this material continues to be used in the automobile manufacturing industry with durability and an average lifespan of up to 15 years.Packaging and containersOne of the most common uses of steel that few people know about is packaging of goods. Food, wine, paint, crude oil, etc. are often preserved and transported in steel tanks to ensure product safety and quality when it reaches the user. Recycled steel is not only used to make containers, belts, etc., but can be manufactured into large containers and then recycled during the life of the steel to make other applications.Steel structureThe use of wood as a building material can deplete natural resources, cause environmental disasters and cannot be recycled or recovered. Wood structures also generate more industrial waste, so steel structures are becoming increasingly popular in housing construction. Not only do they bring modern, sophisticated, cost-effective aesthetic beauty, but steel buildings can be completely recycled after they stop being used.Infrastructure projectBesides housing, steel is also the main material for projects such as bridges, roads, railways, silos, tanks,... Thanks to its high strength, steel is used for frames or roofing, providing high durability and ability to bear large loads. These structures, after long periods of use, may become degraded or need to be removed. At this time, steel materials can be recycled and used as materials for completely new projects, starting a circular steel life cycle.

Purlins are one of the materials that help support the structural framework, most often below the roof. Purlins carry the roof desk load and are supported by building walls, steel beams, rafters,... Purlins are an indispensable part of every project, so choosing the perfect purlin ensures the safety of the entire building. In this article, AG真人游戏 Steel will share some tips for choosing the most suitable purlins to make the roof frame for the project.1. Choose the appropriate purlin materialPurlins combine with rafters to create a roof frame, combining the support of beam frames, walls or steel beams. When choosing the material of the purlin, importer can consider between black pipe steel, galvanized steel or high-strength steel. Each material has pros and cons in terms of strength and cost, so importers need to assess the building design to choose the most optimal material. However, to ensure the safety of the project, steel purlins must be able to withstand high loads, resist corrosion, rust and be unaffected by environmental factors.2. Choose the ideal type of purlinThis is one of the important factors when deciding which type of purlin for your project. C and Z shaped purlins are the two most popular types, have high applicability and unique characteristics as follows:C purlins are made from black or galvanized steel with a C shape and used in structural framework for factories, houses,... Importers can contact AG真人游戏 Steel for advice on the most suitable dimensions, thickness and length for their specific application.Z purlins are manufactured from hot-rolled, cold-rolled, galvanized steel, shaped like the letter Z, so it is easy to stack and connect through bolted joints. Because of this characteristic, the Z shaped purlin has a higher thickness and durability than the C shaped purlin.3. Install purlins properlyCalculating the distance to install purlins compared to the corrugated iron roof in a reasonable, economical and safe way is important in choosing purlins for the project.Firstly, safety and sustainability are the top criteria, requiring the distance between purlins and corrugated iron roofs to be standard and reasonable. Next, if the purlins are not aligned or installed too far or too close, roofing will cost a lot of time and money. Finally, if the purlin distance is not suitable, it also reduces the building's load-bearing capacity, especially making it difficult to repair and maintain periodically.4. No weld/heat cutWelding or heat cutting methods are not used when installing purlins because high temperatures can affect the durability and strength of the purlins.5. Choose a reputable supplier and manufacturerPurlins are a key part in construction projects, so factories always produce many specifications to meet all customer needs. Importers can also find cheap sources from China, India,... but for some countries with strict regulations on C/O or trade defense measures, this option is not feasible. Meanwhile, Vietnam belongs to the group of countries with a developing economy, so it enjoys many preferential duty rates and import policies to the EU, United States, Australia, Mexico, Malaysia,...Vietnam has crude steel output ranked 13th on the world steel map and the largest in Southeast Asia, ensuring abundant and high-quality supply for customers. Many of Vietnam's largest factories do not receive orders directly from importers but through intermediary support units such as AG真人游戏 Steel.AG真人游戏 Steel provides solutions for importing Vietnamese steel to more than 30 countries around the world, with a network of links with many reputable steel factories and shipping lines to promote the fastest and most optimal delivery process.

Steel melting is a complex process, many stages and requires many advanced technologies to create finished products of outstanding quality, meeting the stiff demands in construction. The process has 3 main steps: iron ore treatment, blast furnace molten iron smelting and impurity treatment to form billets and finished products. In this article, AG真人游戏 Steel will describe in detail the steel melting process to help you better understand the nature of this metal.1. What is iron ore steel melting?The process of making steel from scrap steel is relatively simple because the raw material only needs to go through an electric arc furnace (EAF) or an induction furnace (IF) to smelt into square billets and roll out the final product. Meanwhile, steel made from iron ore has to go through a long process with many different complicated stages. Iron ores are rocks containing metallic minerals that are mined and processed to produce steel. Different types of iron ore contain different proportions of iron, divided into 3 basic types:Magnetite: The chemical formula of this ore is Fe3O4 containing 72.41% iron. In nature, the amount of magnetite iron ore is very rare because they possess the highest iron contentHematite: This is an iron ore with 70% iron content, after magnetite, the chemical formula is Fe2O3. In Greek, hematite ore means blood because of their characteristic red color, easily found in Asia, Australia, and Brazil.Pyrit: The chemical formula is FeS2 containing iron content up to 46.67% with metallic, golden copper color. It is the most common of the sulfide minerals.2. What is the process of making steel from iron ore?Step 1: Iron ore processingIron ore with the main components being iron oxides Fe2O3 and Fe3O4 in raw form, with different contents and sizes, processed, mixed according to the required ratio, combined with coke coal, lime and dolomite to put into the furnace to produce liquid cast iron. The product is an alloy of Fe and C with a Carbon content of more than 1.7%. Carbon is an important element affecting the hardness, ductility and toughness of steel. When %C is in the range of 0.8-1%, the steel has the best strength and hardness, but if the ratio exceeds 1%, they begin to decrease. Therefore, the manufacturer reduces C in cast iron and some other harmful impurities (Cu, Ni, Cr) to less than 0.03%. Liquid cast iron water, after being transferred to an oxygen furnace, helps to melt iron ore and reduce the level of impurities such as sulfur, phosphorus,...Step 2: Create a liquid of molten steelFrom the molten cast iron in stage 1, it will continue to be led to the basic furnace or electric arc furnace to treat impurities and combine some other metals such as manganese, chromium, nickel, aluminum, copper, ... to enhance the technical properties of the steel and create the grade required by the market.Step 3: Roll billet, finished steelWhen step 2 has been completed, the liquid metal is put into casting machine systems to form billets or finished construction steel products such as rebar, coil, hot rolled steel,....There are 3 main types of bar stock, slab and bloom, which are cast in two different states: hot casting and cold casting. For bar stock with cross section of 100x100, 125x125 and 150x150, length 6.9m or 12m  for use as coil and rebar. Slabs are often used to make hot rolled coils, cold rolled coils or V-C-U-H sections, while bloom can completely replace both bar stock and slabs.3. Vietnam's modern steelmaking technologyThanks to the closed steel melting process, advanced technology lines imported directly from G7 countries such as Tenova group, Danieli - the leading corporation in Europe and the world in metallurgical and steel rolling equipment, has turned ore into high quality products without impurities. Products after steel melting have impurities below 0.03%, lower than the standards of many fastidious import markets in the world.The process of smelting steel from ore removes many harmful impurities such as S, P, so the finished steel has strength and longer life expectancy. Steel made from iron ore possesses superior physical and mechanical properties and can be rolled into products with a higher diameter and grade of steel such as D55 construction steel, tensile strength reaching over 600N/m2, suitable for construction projects, bridges, ports, skyscrapers,鈥teelmaking is a complex production process, requiring many modern technologies and lines to ensure product quality and not cause pollution to the environment. Vietnam is one of the countries with the leading steel melting capacity in the world.

Besides the usual steels, today manufacturers have continuously innovated and released many improved steel alloys to serve diversified industries. Chromoly steel is known as a steel alloy that is lighter in weight than any other steel, but it also ensures good durability and load capacity.What is Chromoly steel and its important specificationsChromoly steel is a low-alloy heat-resistant steel formed by a combination of "chromium" and "molybdenum", of which the chromium content is 10%. The role of alloying elements will make the product have superior features to ordinary carbon steels because it helps increase durability after undergoing heat treatment.The Chromoly steel grades are conventionally identified by the first two digits of 41, to indicate that this is the designation of chromium and molybdenum steels. An example of the most common type of Chromoly steel can be mentioned as AISI 4130 steel which is currently being used a lot in the oil and gas, aerospace,...CHEMICAL ANALYSISC%Carbon 0.28 鈥� 0.33Mn%Manganese 0.40 鈥� 0.60P%Phosphorus 0.035 maxS%Sulfur 0.040 maxSi%Silicon 0.20 鈥� 0.35Cr%Chromium 0.80 鈥� 1.10Mo%Molybdenum 0.15 鈥� 0.25Some remarkable properties of chromoly steel Limitation in metal corrosionChromium is known as a metal with very high hardness, it also has amazing corrosion resistance. When chromium meets oxygen, it will form a compound Cr2O3, which is the strongest compound of chromium in anti-oxidation. So if Chromium is added to steel, it will create a more protective layer for the steel core, the more chromium content, the higher the steel's ability to resist rust.Outstanding hardnessSimilar to chromium material, when adding the molybdenum to the structure of steel, it will provide superior strength as it increases the hardness of steel and of course, the tensile strength of steel will be greatly improved. A chromium molybdenum steel plate can be designed to withstand a load force of up to 760 MPa.Thanks to this ideal hardness, Chromoly steel helps to maintain the stability of the structure, increase the load-carrying capacity, and minimize the product's warping or distortion when subjected to long-term loads.Good heat resistanceBeyond the feature of increasing hardness, chromoly steel also possesses good heat resistance properties because molybdenum compound allows the steel to survive well under temperatures up to 5800C. Molypden is a heat resistant substance in nature, when combined with chromium, this link will significantly reduce the damage of steel structures in high pressure environments.Long-term cost savingsChromoly steel will cost more than standard steel grades, but in terms of its useful applications in the long-term, this steel will provide the amount of cost-effectiveness for plan. If you are looking for a material that is stronger and lighter than steel but not as expensive as titanium, chromoly steel will be the best choice for you.List of common Chromoly steel's applications Basically, Chromoly steel has some similar features to standard carbon steel, but thanks to the addition of a chromium layer, the steel has enhanced strength and resistance to oxidation, the molybdenum content in the steel also increases toughness. Because of these superior features, the Chromoly steel line becomes useful and is being applied to many industries.Aerospace industryIn the past, steel and aluminum were the popular materials in the aviation industry, but in recent decades, chromium steels are gradually being applied and replacing traditional materials. Thanks to its thermomechanical properties, chromoly steel is often used to support jet engines and landing systems.Manufacture of vehicles and bicyclesDue to the versatile combination of durability properties as well as good load bearing, Chromoly steel is often used to make car chassis. Moreover, based on the advantages of anti-corrosion and high hardness, manufacturers often use them to make gears and automobile crankshafts.Chromoly steel is considered the best material for bicycles. Although Chromoly is known for its hardness beyond standard, it also possesses surprisingly good ductility. Thanks to this factor, manufacturers can freely shape and weld metal parts together to create trendy chassis models that still ensure good durability and bearing capacity.Chemical industriesMany studies have proved that Chromoly steel can suffer from extreme environmental temperature conditions up to 5800C for a long time. Therefore, this steel is widely used in high pressure industries such as oil filtration and chemicals.Depending on the numerous advantages that Chromoly steel brings, it is not difficult to imagine that Chromoly steel will become a standard material for many applications of the field in the future. Therefore, preparing a plan to add Chromoly steel as the main sources for your projects will be a perfect decision for future sustainable development.If you are in need of sourcing reputable Chromoly steel as well as learning more about price segments in the Vietnamese steel market, please contact AG真人游戏 Steel via Whatsapp +84 76 911 2358 or email [email protected].
