If the silicon content in the steel exceeds 0.50-0.60%, silicon is considered an alloy element. Silicon can significantly enhance the elastic limit, yield point, and tensile strength of the steel, making it widely used for spring steel. By adding 1.0-1.2% silicon to quenched and tempered structural steel, its strength can be increased by 15-20%.
The steel is cast into slabs and further rolled into thick and thin coils in the hot strip mill and cold strip mill. These coils go to manufacturers in construction, the automotive industry, white goods, industry and food packaging.

From coarse and rocky iron ore to tough and shiny steel - the making of the alloy is a journey that starts from the crust of the earth, involves complex metallurgical reactions and processes, and demands technological expertise of the highest degree.
This poster shows the various stages of the steelmaking process. The illustration features the different input materials for the blast furnace steelmaking and electric arc furnace steelmaking routes, the main co-products and their uses, and examples of steel applications. An interactive version of this poster is available on worldsteel via this link.
The steel production process is a multi-faceted journey that begins with extracting and processing iron ore, a primary raw material essential to steel making. Iron ore undergoes a series of refining steps to extract the iron content, culminating in the creation of molten iron. This molten iron is then subjected to steel melting, a critical ...
Steel - Smelting, Alloying, Refining: In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. Various chemical reactions are initiated, either in sequence or simultaneously, in order to arrive at specified chemical compositions and temperatures. Indeed, many of the …
The EAF method is the most common steel making process today. Today's modern EAF steelmaking furnaces produce 150 tons of steel per melt, which takes approximately 90 minutes. Custom Metal Manufacturing. Steel is a versatile, affordable and abundant material, making it the perfect substance to use in countless manufacturing …
11. Decline of the Bessemer Process In spite of the basic simplicity, the Bessemer steel suffered from several limitations: • A large part of the heat generated through exothermic reactions is lost in the form of sensible heat of the N2 gas. So, the scrap melting ability of this process is very limited. • The 'N' content in the Bessemer steel is …
The 1850s and 1860s saw the advent of different revolutionary techniques, turned the steel-making process into a mainstream industry. The ensuing technological advancements in the injection technology as well as in the process control, has made mass production of steel easier, and an integral part of the global economy.

Homepage /; About us Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.
Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. ... Step 2 – Primary steel making. There are two main methods for making steel and these are Basic Oxygen Steel making (BOS) and Electric Ark Furnaces (EAF). …
