Fig 4 Flowsheet of Midrex process. Coal based process. In a coal based process, the reactor for the reduction reaction is a rotary kiln which is slightly inclined to the horizontal position. The process of direct reduction is carried out with the operating temperatures maintained in a .
Jul 29, 2010· Lump iron ore in the size range of 520mm can be used in all coal based rotary kiln processes. In gas based processes 70% iron ore pellets and 30% lump iron ore of 1030mm are being used. In general high grade iron ore of 65% minimum Fe (total) with less decrepitating characteristics is preferred for use in rotary kiln. Reductant: Non coking ...
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 noncoking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed. A temperature ...

MANUFACTURING PROCESS Coal based Direct reduction process is classified based on the reducing agent namely solid. Most solid reduction process use noncoking coal as reducing agent due to abundantly available noncoking coal. The process proposed to be adopted is the rotary kiln proposes using Noncoking coal and iron ore.

Coal plays a dual role in the Kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temp. But main role of coal is to supply carbon in the reduction process. Dolomite is used as sulphur scavenger which finally comes out with the char. Char contains ash of coal and other impurities of iron ore.
