Description

[0003] In the reduction process, titanium tetrachloride and liquid magnesium are added to the reactor to generate titanium and magnesium chloride, and the generated magnesium chloride is discharged through the guide pipe and discharge pipe of the reactor. In the distillation process, the pass heater is connected with the reactor, which can be connected before reduction or connected without cooling after reduction. In the distillation process, the unremoved magnesium and magnesium chloride are distilled through the pass heater into the reactor for the next reduction.

[0004] After the reduction and distillation are completed, the reactor cannot proceed to the next titanium lump removal process due to high temperature, and the reactor needs to be cooled before the next process is performed when the reactor is cooled to an operable temperature. In the existing reactor cooling process, personnel hoist the reactor into the cooling water jacket, manually open the indirect water valve of the cooling water jacket, pass indirect water into the interlayer of the cooling water jacket, and remove the temperature on the surface of the reactor through the flow of circulating water. After the indirect water is passed for a certain time, the personnel close the indirect water valve and open the direct water valve to immerse the reactor in the circulating water for cooling. The temperature on the surface of the reactor cannot be detected during the operation, and the opening time of the direct water valve can only be determined by the experience of personnel. It has certain limitations and errors.
