    Steel is made primarily in a two-step process. 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.

    Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygenand entrained impurities (termed "inclusions") in the steel is also important to ensure the quality of the produ
