ABSTRACT:
A method for the continuous direct reduction of metal oxides, ores, etc. to a hot metallized product in solid form. A unique gas seal is employed to prevent the leakage of reduction gas from the bottom of the closed shaft furnace when the product is being discharged which does not affect the discharge temperature of the product.
