Covering device for high-titanium slag smelting furnace

Abstract

The invention belongs to metal smelting equipment, and particularly relates to a covering device for a high-titanium slag smelting furnace. The covering device is characterized in that a high-aluminium insulator (11) is arranged above a furnace body (12); a metal water-cooling furnace cover (14) is connected onto the upper part of the high-aluminium insulator (11); an electrode holder (8) is arranged on each graphite electrode (3) above the metal water-cooling furnace cover (14); a suspension rod clamp (18) is arranged above each electrode holder (8); an insulation connection component (7) is arranged above each suspension rod clamp (18); each electrode balancing suspension rod (6) penetrates through a double-layer platform (15), is sealed through a sealing ring (5) and then is fixedly connected with an electrode adjuster (4); the upper part of each electrode adjuster (4) is connected with the lower end of a steel wire rope (2) through a steel wire rope connection ring (17); and the upper end of each steel wire rope (2) is wound on a pulley (16) and then is connected with a winch. By adopting the covering device of the high-titanium slag smelting furnace, heat loss is reduced; electricity consumption is lowered; the recovery rate is high; black smoke is not generated during production; noise is not caused; and little dust is generated.

Description

technical field [0001] The invention belongs to metal smelting equipment, in particular to a cover device for a high titanium slag smelting furnace. Background technique [0002] The overall production technology of titanium slag in my country is backward. The smelting equipment is characterized by the open electric arc furnace as the main type of furnace. The smelting of high-titanium slag adopts the intermittent smelting process of one-time feeding and one-time furnace. The smelting process: -Blocking the taphole-power failure and pounding the furnace-adding raw materials-lowering electrodes-power transmission smelting-resistance heating period-melting reduction period-refining reduction period-exiting the furnace. This smelting process has shortcomings such as unstable furnace conditions, slag turning and crusting, frequent material collapse, large current fluctuations, poor working conditions, serious flying losses, and low yields. The level of titanium slag smelting tech...

AI Technical Summary

Problems solved by technology

This smelting process has shortcomings such as unstable furnace conditions, slag turning and crusting, frequent material collapse, large current fluctuations, poor working conditions, serious flying losses, and low yields. The level of titanium slag smelting technology determines that the production scale of titanium slag is small. , low efficiency, high energy consumption, poor environment, unstable smelting operation

The raw materials for the production of high-titanium slag in open furnaces are ilmenite concentrate, carbon powder, and coal tar pitch. Coal tar pitch acts as a binder in smelting. Open furnace smelting causes a large amount of toxic gases and dust to enter the atmosphere and pollute the environment.
