Blast furnace raw materials
Did you know?
WebA blast furnace is a reactor which produces an impure form of molten iron, termed ‘hot metal’, from ferrous bearing ores. The principal raw materials used in the blast furnace operation consist of. 1. Metallurgical coke, ferrous bearing feeds and fluxes charged via the furnace top. 2. WebFurther, solid pig iron is used as “pure” raw material and carbon source in EAFs. The blast furnace–BOF route produces almost 66% total crude steel, and EAF route accounts for about 31%, while the blast furnace– open hearth process, which dominated steelmaking in the first half of the 1900s, had only a share of about 3% left [7].
