WhatsApp: +86 18221755073Sponge 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.
