In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.

Step 1 The iron making process. The manufacturing process of steel begins by combining iron ore, lime, and coke into a blast furnace and melting it to form a mass of molten iron. Molten iron contains around 4% impurities, mainly carbon and that is responsible to turn the metal brittle and it needs to be removed.
