Background
The prior production of titanium sponge adopts the Claur method, furnace types are divided into a series furnace type and a parallel furnace type, in the production of the parallel furnace type, the production is divided into a reduction distillation production hot end system and a distillation production cold end system, the reduction distillation production hot end system mainly uses magnesium to reduce titanium tetrachloride to produce titanium and magnesium chloride, the distillation cold end system is used for collecting residual magnesium chloride and magnesium in the hot end system in a high vacuum state, the judgment of the distillation end point according to the distillation time and the distillation vacuum degree in the distillation process brings certain disadvantages, the distillation end point time can not be completely and accurately judged, if the judgment time is too early, the magnesium chloride in the hot end system is not distilled completely, so that the magnesium chloride impurity content in the titanium sponge product is high, the product quality is influenced, if the judgment is made later, the distillation time is too long, so that the distillation power consumption is increased, the production period is prolonged, and the production cost of the titanium sponge is increased.
Disclosure of Invention
The invention aims to solve the technical problems that in the existing titanium sponge distillation production process, the distillation end point time cannot be completely and accurately judged, so that the magnesium chloride of a hot end system cannot be distilled cleanly, the impurity content of magnesium chloride in a titanium sponge product is high, the product quality is influenced, the distillation power consumption is increased, the production period is prolonged, and the production cost of the titanium sponge is increased.
In order to solve the technical problems, the invention adopts the following technical scheme:
a decision maker for titanium sponge distillation production terminal, including locating the hot end large cover 2 on the upper portion of the hot end reactor 1, the hot end large cover 2 is connected with large cover 4 of cold junction through the vacuum cross-over pipe 3, there is a cold junction reactor 8 in the inferior part of the large cover 4 of cold junction;
