Description

Technical field

[0001] The utility model belongs to the technical field of cutting equipment, and in particular relates to a cutting device for a cooling water jacket of a metal magnesium reduction tank. [Background Technology]

[0002] The Pidgeon process and electrolysis are both the main magnesium production processes. Currently, Chinese magnesium manufacturers primarily use the Pidgeon process. The Pidgeon process involves burning dolomite to produce dolomite, which is then mixed with carbon powder and ferrosilicon powder, ground and pressed into pellets. The pellets are then placed in a reduction tank and heated to approximately 1300°C. The reduction tank is sealed and evacuated, connected to a cooling crystallization tank. Magnesium vapor is reduced in the reduction tank and flows under negative pressure into the crystallization tank, which is placed in a cooling water jacket. The magnesium vapor condenses upon cooling, producing crude magnesium. This crude magnesium is then refined in a refining furnace and cast into finished magnesium ingots using a continuous casting machine.

[0003] When the Pidgeon process is used to produce magnesium, the reduction tank is prone to deformation due to its need to withstand high temperature and negative pressure. Usually, the reduction tank will be scrapped after 40-60 days of use, but the cooling water jacket will not be deformed and can continue to be used. Therefore, the deformed reduction tank and the cooling water jacket need to be cut apart. However, in the existing technology, a plasma cutting gun or an oxygen-acetylene cutting gun is usually used manually to advance forward from one side for direct cutting. Due to the difficulty in cutting the deformation of the reduction tank, the manually cut cuts are uneven and the new reduction tank cannot be directly welded. Special equipment is also needed to cut the cuts evenly. The operation process is complicated, which consumes manpower and material resources and reduces the efficiency of replacing the reduction tank. [Utility Model Content]
