Title: PRODUCTION OF DIRECT REDUCED IRON
Abstract:
A method for producing direct reduced iron from iron oxide and carbonaceous material is described. The iron oxide may comprise iron ore and residues from iron and steel production. A mix of iron oxide and carbonaceous material may be continuously fed onto the hearth of a rotary hearth furnace. The material may travel less than one rotation through the furnace at a temperature to cause the reducing agent to react with the iron oxide to form direct reduced iron that may be continuously discharged. The material may be turned over, moved, and mixed when traveling through the furnace. Apparatuses and systems for producing direct reduced iron from iron oxide and carbonaceous material are also described.
