How is Steel Made from Iron

Steel is made from iron by a process called steelmaking, which involves the removal of impurities from the iron and adding various alloying elements to create the desired properties in the final product.

There are two main methods of steelmaking: the basic oxygen furnace (BOF) and the electric arc furnace (EAF). In the BOF process, molten iron is combined with scrap steel and oxygen, which reacts with impurities in the iron to form a slag that can be easily removed. Alloying elements, such as carbon, manganese, and silicon, are added to the molten steel to create the desired properties.
