SPONGEIRON
In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a predetermined range of speeds) at a stipulated temperature (850°C 1,500°C).
