Fact sheet Energy use in the steel industry

as iron ore, coal, limestone and steel scrap. About 75% of steel is produced using the BF-BOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF. After casting and rolling and/or coating, the steel is delivered as strip, plate, sections or bars.
