Radiating method in sponge titanium producing process by magnesium method

Abstract

The invention relates to a radiating method in a sponge titanium producing process by a magnesium method, comprising the following steps: a radiating device is arranged on a large cover of a reactor,and cooling media are continuously led into the radiating device in a reducing process to radiate in the large cover of the reactor. By using the method, when sponge titanium is reduced, because a reaction liquid level has high temperature (generally about 950 DEG C), heat directly radiates on the large cover of the reactor by heat radiation, the temperature of the large cover of the reactor quickly rises, the cooling media are continuously led into a cooling medium inlet of the radiating device and flow out of a cooling medium outlet, thereby realizing effective heat exchange and achieving the radiating effect of the radiating process in the sponge titanium production.

Description

technical field [0001] The invention relates to a production method of titanium sponge, in particular to a heat dissipation method for the reduction process in the production of titanium sponge. Background technique [0002] At present, the industrial production of sponge titanium at home and abroad adopts the method of reducing titanium tetrachloride with magnesium. In the reduction distillation process, most of the furnace types are produced by the inverted "U"-shaped joint method. The advantage of low energy consumption. In order to reduce production costs, all countries regard large-scale equipment as the direction of technological development. However, with the increase of the furnace type, the internal heat dissipation of the reactor is not timely during the reduction period, which will easily cause the central part of the product to sinter, and the sandwiched MgCl 2 Too much, the amount of hard blocks increases, the increase of climbing wall titanium, and the compac...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the reaction temperature in the reactor is too high during the reduction period in the production of sponge titanium, which causes the reduction and feeding speed to be unable to increase, etc., and invented a heat dissipation method in the process of producing sponge titanium by magnesium method
