Jun 30, 2011· Comprehensively deals with the production of sponge iron in the rotary kiln. It is divided into 17 chapters. The initial chapters give a brief on the fundamental theories and basic principles of sponge iron production, commercially used DR (direct reduction) processes and physico-chemical principles of sponge iron production. The book then …

Since DRI is produced by removing oxygen from iron ore, its structure is just like a sponge with a network of connecting pores. These pores result in a large internal surface area which is about 10,000 times greater than the internal surface area of solid iron. Due to this, DRI is also known as Sponge Iron.

Sponge Iron is iron ore reduced directly in solid state using coal gas, natrual gas or coal as reductants and is also known as Directly Reduced Iron (DRI). Sponge Iron or Direct Reduced Iron (DRI) Sponge iron is the metallic product formed by the reduction (removal of oxygen) of iron ore at temperature below the fusion point of iron while it is still in solid …

The formation of accretions or 'rings' in rotary kilns used for the manufacture of directly reduced iron (sponge iron) affects the residence time of the charge, kiln hold-up, and the kiln output to a great extent. In this part of the work, the effect of ring formation was simulated at room temperature in a scaled-down model of a rotary kiln by inserting …
