Direct Reduced Iron and its Production Processes – IspatGuru
Fig 1 DRI process principle Major DRI production processes are either gas based or coal based Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant In the gas based plant the reactor, the reduction reaction takes place is a shaft furnaceJul 29, 2010 In order to have effective control and monitoring of process parameters, Direct reduction plant comprising rotary kiln, rotary cooler, waste gas cleaning system, product separation system, in plant dedusting system, PLC system, Measuring and control systems shall projects in direct reduction process in rotary plantDirect reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal Many ores are suitable for direct reductionDirect reduced iron Wikipedia

IBUtec The Rotary Kiln Experts for Trials and Production
Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction These treatments can be applied to powders, granulates, suspensions and green bodiesThe increase in the demand of sponge iron is also due to the fact that it is used as a substitute for coking coal which is available in scarcity in the world This book comprehensively deals with the production of sponge iron in the rotary kiln The book is divided into 17 chapters The initial chapters give a brief on the fundamental theories Sponge Iron Production in Rotary Kiln Arabinda Sarangi
