Utilization of Kiln Accretion as a Raw Material in Rural ...
Sponge iron production in various industries was carried out through the Direct Reduction Iron (DRI) process. The key step in DRI processes is the reduction of iron oxide (FeO) to metallic iron stage. But during the production process there is a tendency of accretion formation in the temperature range of 900 oC to 1100 oC inside the Rotary kiln
