Direct Reduced Iron Tunnel Kiln reduction reaction in tunnel kiln process for iron ore IronManufacturing process related to the specified manufactures iron powder using magnetite ore Fe3O4 and carbon as materials The reduction process takes place in a gas fired tunnel kiln at around 1200176C for 60 hours refined by oxidation reactionsSPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE,oC in the tunnel kiln. It was observed that metallization for indurated iron ore pellets, and concentric chargingwere limited to 80% to 83% where as composite pellets had a metallic iron of 88% to 89%. Thermal efficiency of tunnel kiln is quiet low and depends on the length of the kiln.
