Abstract
Apparatus for reducing particulate iron oxide and producing molten iron in which coal and oxygen are injected into a molten iron bath to melt the iron, gasify the coal and produce a hot off-gas which is then used as the reductant in a counterflow shaft furnace to reduce iron oxide pellets and/or natural ore in a continuous manner. The hot reduced iron product from the shaft furnace is discharged directly into the molten iron bath from which the molten iron product is discharged.
