  • Direct reduced iron processtec-science

    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.
