Sponge Iron Production By Direct Reduction Of Iron Oxide
This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is ‘directly reduced’ in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces (sometimes even in basic oxygen furnaces) to produce liquid steel. Such a process combination enables steel to be produced without using coking coal, which is an expensive input in the normal blast furnace—basic oxygen furnace route of steelmaking adopted in integrated steel plants.

I study this book very carefully and get more knowledge about types of reactions,heat transfer sequence,amount of heat generated and utilised during operation,rotary kiln and cooler details and finally different types of methods for production of DRI.
