The blast furnace produces liquid hot metal by melting iron ore in a reducing atmosphere. Iron ore is composed out of iron and oxygen. By melting the iron ore in a reducing atmosphere we are able to remove the oxygen. The raw materials used in the blast furnace, coke and sinter, are loaded into the blast furnace via weighing hoppers.
