Description

Technical Field

[0001] The utility model relates to the technical field of copper converters, in particular to a copper converter with a long service life. Background Art

[0002] Copper converter is an important smelting equipment, widely used in the metallurgical industry, mainly used to convert copper concentrate or matte into pure copper or blister copper. It usually consists of a blast furnace tube and a combustion chamber. It melts the raw materials at high temperature to separate the copper for subsequent processing.

[0003] The inner wall of the copper converter is provided with a plurality of tuyeres for continuously blowing in a large amount of air to complete the oxidation reaction. That is, during the copper converter blowing process, the air blown in through the tuyeres reacts with the copper matte in the furnace to generate crude copper and slag. The tuyeres are generally arranged in tuyere bricks. Therefore, when the raw materials in the copper converter are blown, the raw materials near the tuyere react more violently, so that the loss rate of the tuyere bricks is greater than that of the lining bricks at other positions. The replacement of the tuyere bricks requires the copper converter to be shut down, and manual entry is performed inside the copper converter to disassemble and assemble the tuyere bricks, which makes the replacement of the tuyere bricks very inconvenient. For example, the Chinese utility model patent disclosed in the existing publication number CN206418171U: A converter The application discloses a tuyere brick and a converter lining. The tuyere holes are all arranged in the second brick, and there is no intersection between the tuyere holes and the first brick and the second brick. The use of the above-mentioned converter tuyere bricks can reduce the abnormal loss of the tuyere bricks, thereby increasing the service life of the converter cycle. However, the outlet end of the tuyere hole opened in the second brick is still placed in the copper converter. Therefore, the outlet end still needs to directly supply air to the copper converter. The second brick located at the outlet end is the same as the existing tuyere brick. The second brick located near the outlet end will cause the raw materials near the outlet end to react violently due to the high wind speed, which will still cause loss to the second brick. In addition, when replacing the first brick and the second brick, it is also necessary to enter the furnace body, which makes the maintenance process inconvenient. Utility Model Content
