is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic ironthe raw material has better applicability Fig. 1 earlier titled as Sponge Iron Production in Rotary Kiln 2017· Most plants employ reduction process which is carried out in rotary kilns. These plants use wide variety of raw materials and non-coking coal. The quality of these materials has direct bearing on the process as well as the product. Some plants do not use iron ore directly. These plants use iron ore pellets in the rotary kiln.Jun 23

pressure calciner and multiple linear regression (MLR).The present work is an attempt to conserve energy in coal based sponge iron industry incorporating certain design modifications without disturbing the process technology. Case-1 accounts for preheating of air using waste gas exiting from ESP. For case-2 initially water is heated using hot sponge iron exiting rotary kiln and further hot water is used to preheat air.The inclination and the rotary motion of the kiln ensure that the raw materials move from the feed end to the discharge end of the kiln and during this movement the actual reduction of iron ore to iron takes place. The material discharged from the kiln is taken to a rotary cooler for cooling and the cooled product is separated from the coal char.Feb 14
