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 .
India is largest producer of Sponge Iron in the world. Most of this production comes from secondary steel industry using rotary kiln process. The design was initially introduced by Germany but later has been almost completely altered by Indian consultants and technology providers.
The 2D geometry of rotary kiln of sponge iron process is developed using ANSYS and shown in Fig. 2. Feed, a mixture of iron ore, coal and dolomite, enters to the kiln as indicated in Fig. 2.

May 01, 2013· Sponge Iron (SI): DRI is also known as Sponge Iron because of its spongy micro structure. . ore lumps or iron ore pellets with the help of noncoking coal in Rotary Kiln .
Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction.
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)].
