  • Sponge Iron Production From Ore Coal

    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 tunnel kilns are comfortable with coal fines and mill scale; uniform product quality; production cost from tunnel kilns is lower than that from rotary kilns; extremely low on environmental pollution; the research & development team of electrotherm has extensively worked upon this process of sponge iron making and we have successfully produced sponge iron from our PD tunnel kiln at our steel making complex at samakhyali, kutch. sample of the product from our tunnel kiln
