Aerodynamics Inside A Sponge Iron Rotary Kiln
SPONGE IRON PLANT
Non-coking coal is required in sponge iron production, since the coking reaction leads to formation of rings inside the kiln. Practically permissible caking index is 3 maximum for rotary kiln operations. 2) Low ash contents:- High ash leads to under utilization of the kiln volume available for reduction.

Sponge Iron
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 ...
