Sponge iron is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C.
Iron Ore Pellet is used for reduction. After the reduction of iron ore pellet, the product resembles a sponge because of pores left behind after the removal of oxygen. As such it is called Sponge Iron.
Sponge iron making is a process in which iron ore lumps (typically 5mm- 18mm size) are tumbled with a 'select' grade of iron-coking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air-cooled, magnetically separated and screened.
Sponge iron is formed through the reduction of iron ore to metallic iron through reaction with carbon in the form of coal, etc. at approx. 1100 degrees Celsius. Over the years, the shortage of expensive melting scrap has made sponge iron a significant raw material for manufacturing high- quality steel.
