the blast furnace/basic oxygen furnace (BF/BOF) process or the electric arc furnace (EAF) process. The BF/BOF process first makes iron by smelting iron ore in a blast furnace and then using that iron to make steel in a BOF. In the EAF process, iron and steel scrap and often direct reduced iron are melted to produce steel.
