HEAT TREATMENT OF IRON ORE AGGLOMERATES WITH

2010-7-21  When the pellets undergo metallurgical processing, their mechanical strength is a measure of their resistance to degradation by breakage due to impacts and abrasion to which they are exposed in the upper part of the blast furnace. In this study, heat treatment of iron ore agglomerates with microwave energy is investigated.
