Pathways To Decarbonisation Episode Two Steelmaking

Coal in the form of metallurgical coal and pulverised coal act as the active agents or reductants that strip away oxygen from the iron ore to yield metallic iron with temperatures inside the blast furnace reaching over 2000c the resulting metallic iron melts and the liquid hot metal is cast from the furnace and transported to the basic oxygen furnace
