Problems solved by technology
The electrolyte component adjustment tank and the refining tank adopt the anode plug-in electrolytic cell, and the graphite electrode is suspended on the electrolytic cell cover. Due to the oxidation of the air, thinning and fractures often occur at the interface between the electrolyte and the air, and the longest service life can only be As a result, the production process is often stopped for maintenance due to graphite electrode breakage and replacement, which not only seriously reduces production efficiency, but also during the electrode replacement process, because the electrolyte cannot be purified in time, and it is brought in during the replacement process. Impurities seriously affect the normal operation of the electrolysis system

Embodiment Construction
[0018] Such as figure 1 Shown is a control method for prolonging the service life of graphite electrodes that can effectively improve production efficiency and significantly reduce the frequency of replacement and maintenance of graphite electrodes provided by the present invention, and the graphite electrodes used in the manufacturing method. The control method prolongs the described graphite electrode 1 by reducing the temperature of the graphite electrode 1 at the gas-liquid boundary 2, and forming a protective layer 3 on the gas-liquid boundary 2 of the graphite electrode 1 to reduce the high-temperature oxidation rate of the graphite electrode 1. The service life of the graphite electrode 1; a refrigerant input structure is arranged on the upper end of the graphite electrode 1. In this application, a refrigerant input structure is set on the upper end of the graphite electrode 1, and then based on the refrigerant input structure, the low-temperature refrigerant is continu...

The invention discloses a control method used for prolonging the service life of a graphite electrode and the graphite electrode for the control method and belongs to the technical field of metallurgy production technologies and equipment design and manufacturing. The control method used for prolonging the service life of the graphite electrode and the graphite electrode for the manufacturing method are provided, wherein the control method can effectively improve the production efficiency and obviously lower the replacing and maintaining frequency of the graphite electrode. According to the control method, the temperature of the graphite electrode at the position of a gas-liquid interface is reduced, a protection layer is formed on the graphite electrode at the position of the gas-liquid interface to reduce the high-temperature oxidization speed of the graphite electrode, and therefore the service life of the graphite electrode is prolonged. A refrigerant input structure is arranged at the upper end of the graphite electrode.
Description
technical field [0001] The invention relates to a control method, in particular to a control method for prolonging the service life of graphite electrodes, and belongs to the technical field of metallurgical production technology and equipment design and manufacture. The present invention relates to a graphite electrode used in said control method. Background technique [0002] Magnesium electrolysis is the core process for establishing the magnesium-chloride cycle in the production process of sponge titanium. At present, the multi-pole tank technology is more popular. The assembly line magnesium electrolysis technology has relatively low requirements on raw materials, making it comparable to the multi-pole tank technology. Still competitive and attractive in the electrolysis process. The assembly line magnesium electrolysis technology connects multiple non-partition electrolyzers, refining tanks, electrolyte composition adjustment tanks and magnesium-electrolyte separation...
