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. It also increases the consumption of fixed carbon, since additional energy is consumed in ...

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 ...

Coal based Direct Reduction Rotary Kiln Process – IspatGuru

14/02/2017· Coal based direct reduction process is based on the solid reducing agent which is non-coking coal. The reaction takes place at high temp (1000 deg C to 1100 deg C). Coal plays a dual role in the kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temperature. But main role of coal is to supply carbon for the reduction process. Dolomite ...
