Making iron & steel - blast furnace | ArcelorMittal
Before iron ore can be used, oxygen must be removed from it. Known as ‘reducing’, this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two
