Steelmaking - Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and a versatile material. Modern steelmaking processes can be divided into two egories: primary and secondary.
