SPONGE IRON PRODUCTION FROM ORE -COAL

2014-9-2  Abstract: Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal. However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process.

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 ...

Sponge Iron - What is Sponge Iron and how is it made ...

2021-10-5  Iron oxide ores taken out from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction, as the iron ore is warmed up with carbon, it results in a surface with hole marks, hence the name “Sponge Iron”. The commercial process is a solid solution reduction, also called Direct-Reduced Iron (DRI).
