RedSmeltTM is a two-step pre-reduction and smelting process, combining a Rotary Hearth Furnace (RHF) and an EAF Smelter to convert steelmaking residues or iron ore into pig iron or alloys and slag.

This new technology has been developed to meet the growing demand for a low-cost and environment-friendly ironmaking alternative to the traditional blast furnace route. This process reaches a production capacity of 0.3 -1.0 mtpy of hot metal and may be used to treat the widest range of fine iron ores and steelmaking residues.
