REDUCTION SMELTING SYSTEM AND REDUCTION SMELTING METHOD FOR VANADIUM-TITANIUM MAGNETITE ORE OR ILMENITE

摘要

A reduction smelting system (10) and reduction smelting method for vanadium-titanium magnetite ore or ilmenite. The reduction smelting system (10) for vanadium-titanium magnetite ore or ilmenite comprises: a rotary kiln (101) used for pre-reducing magnetically separated vanadium-titanium magnetite ore or ilmenite, the rotary kiln (101) being provided with a first feeding port, a calcine outlet, and a burner nozzle mounting port; a burner nozzle used for jetting flames into a kiln cavity of the rotary kiln, the burner nozzle being disposed at the burner nozzle mounting port; an electric furnace (102), the electric furnace (102) being provided with a second feeding port, an iron discharging port, a slag discharging port, and a smoke outlet; and a hot material conveying apparatus (103), one end of the hot material conveying apparatus (103) being connected to the calcine outlet, and the other end of the hot material conveying apparatus (103) being connected to second feeding port.
