Sponge iron is a highly ferrous ore from the direct reduced iron process! In order to prevent excessive re-oxidation of the sponge iron in the ambient air, it must be cooled down in the lower region of the shaft furnace. Carburisation as in the blast furnace process does not occur in the DRI-process, as coke is not used as a reducing agent.

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
