Ironmaking in Rotary Hearth Furnace. Ironmaking in the rotary hearth furnace (RHF) is a direct reduction process which utilizes noncoking coal for the reduction of iron ore. The RHF is the process reactor which consists of a flat, refractory hearth rotating inside a stationary, circular tunnel kiln.
ITmk 3 Process of making Iron Nuggets This concentrate is converted into green pellets. Non coking coal is used as a reductant. The pellets are charged into a Rotary Hearth Furnace (RHF), heated to 1350 Deg C, reduced, melted and separated into metal and slag.
