Most of the plants in India use DRI process—a solid state direct reduction process by which iron ore is reduced to sponge without phase change (Figure 1). Raw material mixiron ore, dolomite and coal are fed to one end of rotary Kiln and product sponge iron along with char is taken out from the other end. Apart from this, primaryWELSPUN STEEL LIMITED,The process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product. For the direct reduction of iron ore the main furnace used is rotary kiln. The
