SPONGE-IRON Shakambhari Group

Sponge Iron, also known as Direct Reduced Iron is produced from Hematite Iron ore (5 to 18 mm size) by removing the oxygen by direct reduction process using non coking coal as the fuel and reducing agent in Rotary Kiln. Sponge iron is rich in Metallic Iron (Pure Iron) with consistent chemical &

Sponge Iron an overview ScienceDirect Topics

DRI, also known as 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 oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H
