Sponge Iron an overview ScienceDirect Topics

Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H 2 ) which are generated through partial oxidation of coal (Reaction 3.3.1 ), reforming of methane by CO 2 /H 2 O (Reactions 3.3.2 and 3.3.3 ), or partial combustion of natural gas (Reaction 3.3.4 ).

OPERATIONAL ASPECTS OF SPONGE IRON

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.

Technology Tata Steel Long Products Limited

2020/02/07· Iron ore and non-coking 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 950-1050 o C.

Flow of materials in rotary kilns used for sponge iron

1983/09/01· Looking forward to the need of developing coal-based 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
