SPONGE IRON PLANT

The process proposed to be adopted is the rotary kiln proposes using Non-coking coal and iron ore. Iron are undergoes the following reduction reaction in all the processes Fe2o3 + 2 CO = 2 Fe + 3 Co2 As shown in above reactions, carbon monoxide is reducing gases. These reducing gases can be obtained by controlled combustion

Accretion Control in Sponge Iron Production Kiln using

This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed.
