OPERATIONAL ASPECTS OF SPONGE IRON …

1. Krupp Sponge Iron Process 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.

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.

Accretion Control in Sponge Iron Production …

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.

Coal based Direct Reduction Rotary Kiln Process ...

The quality of these materials has direct bearing on the process as well as the product. Some plants do not use iron ore directly. These plants use iron ore pellets in the rotary kiln. Raw material mix consisting of iron ore, dolomite and non-coking coal is fed at the one end of the rotary kiln and is heated by coal burners to produce DRI.
