Behavior of three non-coking coals from Iranian’s deposits ...

Jan 01, 2017  The tunnel kiln direct reduction of iron is a volumetric method in which raw material consumption is based on the volumetric capacity of refractory crucibles. This process requires non-coking coal with less than 10% volatile material, ash content up to 25%, more than 65% carbon and particle size that may typically vary between 0.5 mm and 7 mm.
