CA 2322935

An apparatus for producing a reduced metal includes a moving hearth reducing furnace, a feeding section, a metal discharge section, a gas discharge section, and a regenerative burner. The moving hearth reducing furnace heats a raw material composed of a metal oxide component and a carbonaceous reducing component to form the reduced metal. The feeding section feeds the raw material into the moving hearth reducing furnace. The metal discharge section discharges the reduced metal from the moving hearth reducing furnace. The gas discharge section discharges waste gas from the furnace and is disposed in a reducing process between the moving hearth reducing furnace and the metal discharge section. The regenerative burner functions as a heat source for the moving hearth reducing furnace.
