METHOD OF IRON SMELTING AND UNIT FOR REALIZATION OF THIS METHOD Russian patent published in 2000 - IPC

FIELD: ferrous metallurgy; iron making. SUBSTANCE: lump solid fuel is loaded in working space bounded by shaft and finely ground iron-ore material is blown together with pulverized coal fuel and gaseous fuel into other working space bounded by dome-shaped reactor at simultaneous oxygen-enriched hot blast. Shaft includes loading device, gas exhaust pipes and is connected with dome- shaped reactor by means of furnace well; dome-shaped reactor is provided with tuyere apparatus in its center portion and with burner in its lower portion and in dome. Furnace well is equipped with iron tap-holes and slag holes. EFFECT: reduced height of metallurgical unit; low requirements for fuel and iron-ore material. 4 cl, 1 dwg, 1 ex
