Accretion Control in Sponge Iron Production Kiln using ...

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 non-coking coal [Patra et al, (2005)]. The ...

The process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product. Sponge iron manufacture is highly sensitive to raw material characteristics.
