SPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE

In the year 1908 use of tunnel kiln started for iron oxide reduction. This process was invented by E.Sieurin as Hoganas process [3]. In 1954, more kilns came in operation in SWEDEN and USA. Presently it is more popular in China for sponge iron production from beneficiated iron ore fines cakes. In this process, the material passes through

Sponge Iron Production Process Arij Trading

Market share: About 23% of sponge iron total production. 4) Tunnel furnace process . This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent.

Sponge Iron an overview ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. 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
