Abstract

The invention provides an electric furnace for melting titanium slag, which comprises a furnace lid, a furnace mantle, a furnace lining, a feed opening, electrodes, a slag hole, a slag notch and a taphole, and is characterized in that the diameter of the pole circle of the electric furnace is 2500mm-3500mm, the operation power of the electric furnace is 15000kVA-30000kVA, the hearth height of the electric furnace is 5000mm-9000mm, and the diameter of a molten pool of the electric furnace is 8000mm-12000mm. According to the embodiment of the invention, the electric furnace for melting titanium slag has stable furnace condition and high heat efficiency when smelting titanium slag.

Description

technical field [0001] The invention relates to a titanium slag smelting equipment, in particular to a large electric furnace for smelting titanium slag. Background technique [0002] The main raw materials of the titanium industry are ilmenite and titanium-rich materials, and titanium-rich materials include titanium slag, artificial rutile and natural rutile. As the raw material for producing titanium slag, ilmenite is to remove impurity elements such as iron, calcium and magnesium to the greatest extent so as to enrich titanium. High-titanium slag is a kind of titanium material with high titanium dioxide content smelted from titanium concentrate, which occupies a dominant position in the world's titanium-rich materials. [0003] The production of titanium slag adopts electric furnace smelting process. According to the shape of the electric furnace, the electric furnaces used for smelting titanium slag include circular furnaces and rectangular furnaces; according to the c...
