Device and technology for preventing vacuum channel from being blocked in titanium sponge production

Abstract

The invention discloses a device and technology for preventing a vacuum channel from being blocked in titanium sponge production. The device comprises a condenser, a sieve plate, a reactor, a magnesium chloride pipe, a large cover, a large cover vertical pipe and a heating furnace; the large cover vertical pipe is arranged in the center of the large cover. After reduction production is finished, the assembled reactor, the sieve plate and the large cover are suspended into the condenser, cooling water is introduced into the condenser, a passage is connected, the magnesium chloride pipe is connected with a vacuum system, then, pressure is exhausted, the temperature is increased to 850 DEG C, meanwhile, rough vacuum is started for performing distillation, the temperature continues to be controlled to be 850 DEG C, and low-vacuum distillation production is performed for 30 h; after 30 h is reached, the temperature is controlled to be 900-980 DEG C, high vacuum is started for performing distillation production, and finally distillation is ended. An evacuation pipe is omitted, the magnesium chloride pipe is adopted for evacuation, large cover welding lines are reduced, and the product air inflow rate is lowered; the distillation production period is shortened by about 10 h; argon consumption is reduced; the distillation production power consumption is reduced; the labor intensity ofoperators is lowered, and the working environment is improved.

Description

technical field [0001] The invention relates to the production of sponge titanium, in particular to a device for preventing vacuum channel blockage in the production of sponge titanium and a process thereof. Background technique [0002] At present, the domestic and foreign industrial production of titanium sponge adopts the Claure method, and the inverted U-shaped joint method developed in the direction of large-scale furnace type ( figure 1 As shown) to produce sponge titanium, the inverted U-shaped joint method is to connect the hot end of reduction production and the cold end system of collecting condensate through the aisle horizontal pipe to form a production system. After the reduction production of sponge titanium, there are sponge titanium, and some magnesium chloride and magnesium in the hot-end reactor. A reactor is installed in the cold-end system to collect magnesium chloride and a small amount of magnesium distilled from the hot end. After the distillation is c...
