Reduction Behaviour of Iron Ore–Coal SpringerLink

Reduction of iron ore–coal composite pellets in multi-layers at rotary hearth furnace (RHF) is limited by heat and mass transfer. Effect of various parameters like pellet shape size and bed packing material that are supposed to influence the heat and mass transfer in the pellet bed have been investigated on the reduction behaviour of iron ore–coal composite pellets at 1250 nbsp°C for
