In the Direct Reduced Iron DRI plant, production of sponge iron using a solid reductant involves reducing iron ore lumpspellets with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln which is inclined and rotates at a pre-determined range of speeds at a stipulated temperature 850 C -1,500 C.

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 8001200 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 ...

Nov 13, 2020 In coal-based DRI process, accretion formation inside the rotary kiln is a genuine complex problem. Accretion formation in a rotary kiln of 100 tpd DRI plant has been investigated. The nature of accretion formation with respect to the charge burden and operational parameter have been discussed. High ash content in the coal and excess use of dolomite lead to accretion formation.

The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran 1978 to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company
Sep 01, 2018 The location of Sponge Iron Plant should be at least 500 m away from National Highway and State Highway. The radial distance between two Sponge Iron Plants should be 5 km for plants having capacity 1000 TPD or more. Sponge Iron Plants can be established in designated industrial areasEstates as notified by State Government.
