Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in the presence of hydrocarbon-rich gases, carbon monoxide, or elemental carbon. Direct reduction refers to processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. The product of such solid state processes is called direct reduced iron.
In the Direct Reduced Iron (DRI) plant, production of sponge iron is done using coal. This reduction process is done in a rotary kiln at temperature of around 850ᵒC-1050ᵒC.
The material discharged from the kiln is taken to a rotary cooler and cooled product is separated from coal char.
Sponge iron Ranging from 3mm to 18mm
Sponge iron produced by us has high iron content and has high degree of metallization. It has less Sulphur and Phosphorous content and has uniform and consistent quality. It generates minimum dust during handling, flows easily in bins, pipes and conveyers for continuous charging.
