OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION

2012-1-10  The Krupp. Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron. Depending on its content of volatile matter, the coal is part-ly blown into the kiln
