Production routes for steel

The iron from the blast furnace is then further refined and converted to steel in the basic oxygen furnace (BOF). Depending on the plant, 20-30% of scrap is added to this process, primarily to regulate the temperature. In the Electric Arc Furnace route (EAF) 100% scrap used. This is the remelting of steel without the use of primary raw materials.
