23.3: Metallurgy of Iron and Steel
Figure 23.3.1 23.3. 1: A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged with alternating layers of iron ore (largely Fe2O3) and a mixture of coke (C) and limestone (CaCO3). Blasting hot air into the mixture from the bottom causes it to ignite, producing CO and raising the temperature of the lower part of the ...

Process of Steel Manufacturing | JSW MI
Iron-making; This is the first step in the manufacturing of pure steel. In this step, the raw materials like iron ore, coal and lime are melted in a blast furnace. This results in the formation of molten iron, also known as hot metal, which still contains 4-4.5% of carbon and other impurities, which makes it brittle. These have to be ...

In addition, carbon can increase the steel's cold brittleness and aging sensitivity. 2. Silicon (Si): Silicon is added in the steelmaking process as a reductant and deoxidizer, so calm steel contains 0.15-0.30% silicon. If the silicon content in the steel exceeds 0.50-0.60%, silicon is considered an alloy element.

Steel manufacture
Iron and steel making by-products. As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.
