Iron ore and noncoking coal are the prime raw materials for the production of sponge iron. These are charged into a rotary kiln in requisite proportion along with some dolomite. Coal plays a dual role in the process by acting as a reductant as well as a fuel for providing heat to maintain the requisite temperature inside the kiln at o C.

Coal based Direct reduction process is classified based on the reducing agent namely solid. Most solid reduction process use noncoking coal as reducing agent due to abundantly available noncoking coal. The process proposed to be adopted is the rotary kiln proposes using Noncoking coal and iron ore.
2 KILN BASED SPONGE IRON PRODUCTION PROCESS Rotary kilns are found in many processes that involve processing of solids. 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 noncoking coal [Patra et al, (2005)]. The ...
Looking forward to the need of developing coalbased sponge iron technology in India, a country having no significant resources of either coking coal or natural gas, the Research and Development Division of the Tata Iron and Steel Company Limited (TISCO) set up a rotary kiln based direct reduction pilot plant in 1975. In this pilot plant, a totally indigenous technology for production of ...
