Description
Technical Field
The invention relates to the technical field of metallurgical furnaces, in particular to a muzzle brick assembly and a metallurgical furnace with the muzzle brick assembly.
Background
Muzzle bricks are very important components of metallurgical furnaces for fixing and protecting lances. The muzzle brick is in a severe environment, particularly in a high-temperature environment for a long time, and is eroded and flushed by melt, so that the service life of the muzzle brick is difficult to guarantee. When the muzzle bricks are damaged, the spray gun is exposed to the high-temperature melt, so that the damage process of the spray gun is accelerated. When the spray gun and the muzzle brick are seriously damaged, the spray gun and the muzzle brick need to be integrally replaced by stopping the furnace, and the production operation rate and the product quality are affected.
Improving the service life of muzzle bricks is one of technical bottlenecks in the smelting industry, no better solution exists at present, and in the existing research, two imperfect treatment methods exist. Firstly, a water jacket is adopted to replace the original muzzle brick, and the flowing medium in the water jacket is water; the other is to replace muzzle bricks with steel sleeves or copper sleeves, and at high temperature, the internal flowing medium is liquid metal or cooling oil. Both methods can increase the life of the components near the muzzle to some extent, but have certain limitations of use. When water is used as a cooling medium, the corrosion condition of the water jacket needs to be strictly monitored, and if the water jacket leaks, a large potential safety hazard can be caused. Liquid metal and cooling oil are less in risk of leakage, but are expensive in cost and not suitable for large-scale popularization.
Disclosure of Invention
The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a muzzle brick assembly and a metallurgical furnace having the same, which has the advantages of long service life, fast heat transmission, high safety, better protection of the spray gun, and direct replacement of the existing muzzle brick without changing the structure of the furnace.
