Crude Steel - an overview | ScienceDirect Topics

Iron ore-based steelmaking accounts for more than two thirds of the production of crude steel in the world. In this process, iron ore is reduced to iron by mixing it with coal/coke and limestone in a blast furnace (BF). In the second step, the iron is converted into steel using a basic oxygen furnace (BOF).
