DRI RHF Rotary Hearth Furnace
The process flow of the RHF is as follows: iron concentrate powder or iron oxide dust, reducing agent, and binder are mixed to form balls, dried and directly loaded into the RHF. At a high temperature of 1250-1350 ℃, as the furnace bottom rotates, the furnace material passes through the preheating and reduction zone in sequence, and about 85% or more of the iron oxide is reduced into metallic pellets.
