Production of.Process - ResearchGateMay 22, 2015 . 16 Production of Sponge Iron through Tunnel Kiln Process. APR Dr SS Bedarkar and Ram Singh. By Dr S S Bedarkarand Ram Singh. India's total production of steel for the year 2009 was about 56.7 million. TPA. Out of which almost 40% of the steel is being melted using induction furnace route. Sponge.sponge iron production from ore -coal composite pellets in tunnel kilnTunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns. The material bed in Tunnel kiln being stationary, it does not require high strength and thermal stability of the raw material.
