METHOD AND APPARATUS FOR PRODUCING MOLTEN IRON FROM IRON OXIDE WITH COAL AND OXYGEN

摘要

A method and apparatus for reducing particulate iron oxide and producing molten iron on which coal and oxygen are impinged onto a molten iron bath in a closed vessel to melt the iron and gasify the coal. The hot off gas from the vessel is removed and used as the reductant in a counterflow shaft furnace to reduce iron oxide pellets and/or iron ore in a continuous manner. The hot reduced product from the shaft is discharged directly into the molten iron bath and melted.
