Embodiment 1

[0022] Such as figure 1 As shown, a heat dissipation method in the process of producing sponge titanium by a magnesium method is characterized in that a heat dissipation device 2 is provided on the reactor cover 1, and during reduction, a cooling medium is continuously introduced into the heat dissipation device 2 to achieve The large cover of the device is used for heat dissipation.

[0023] Utilize the method of the present invention, when sponge titanium is reduced, because reaction liquid surface temperature is higher (generally about 950 DEG C), heat mainly directly radiates on the big reactor cover by heat radiation, the temperature of reactor big cover rises sharply, The cooling medium is continuously fed into the cooling medium inlet 3 of the cooling device 2, and the cooling medium flows out from the cooling medium outlet 4, so as to realize effective heat exchange and achieve the heat dissipation effect in the reduction process of titanium sponge production.

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...
