Description

Technical Field

[0001] The present invention relates to the technical field of slag removal for vertical magnesium metal tanks, and specifically to a slag removal device and method for smelting vertical magnesium metal tanks. Background Art

[0002] Currently, when the Pidgeon process vacuum thermal reduction is used to produce magnesium, calcium, and strontium metals with bottom slag discharge from vertical tanks, due to the high temperature state, the raw materials are in a molten state, and slag will form on the inner wall of the reduction tank. The slag formation mainly concentrates on the lower part of the reduction tank and gradually accumulates upward. During the production process, after each production cycle, the magnesium metal is reduced and extracted, and excess slag will remain in the tank. After the slag is removed, new materials need to be loaded before entering a new production cycle. The existing slag cleaning method is to pull out the reduction tank and manually clean the slag after cooling. Generally, after cooling for several days, the slag shrinks after the temperature drops, and then manual cleaning can be carried out. In such a slag cleaning method, the reduction tank is frequently pulled out for cooling and cleaning, resulting in increased energy consumption. Each time the reduction tank is replaced, heat insulation materials such as aluminosilicate fiber cotton for sealing need to be replaced simultaneously, and cooling water pipes and vacuum pipes need to be plugged and unplugged, with a long operation time and being cumbersome.

[0003] The current technology is to manually remove the slag with a shovel. Since the slag in the tank has a temperature of several hundred degrees, the work is very difficult. There are also some slag removal machines that use spiral or chain scraping methods for slag removal. However, the structures of these machines are complex, and it is not convenient to clean the larger pieces of residue attached to the inner wall of the vertical magnesium metal tank, and they are not convenient to use.
