However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns. The material bed ...

Direct Reduced Iron and its Production Processes IspatGuru

Direct Reduced Iron and its Production Processes IspatGuru

Mar 16, 2013 Iron ore is used mostly in pellet andor lumpy form. Oxygen O2 is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron Fe is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Modelling and optimization of a rotary kiln direct

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
