Description

Technical Field

[0001] The utility model relates to the technical field of ladle maintenance, and more specifically, to a tooling based on ladle cold repair. Background Art

[0002] A ladle, also known as a molten steel ladle or a steel melting bucket, is an important production equipment for transporting molten steel during the casting process of steelmaking continuous casting. Due to long-term contact with high-temperature molten steel, the refractory lining material of the ladle is easily eroded, which is the main determinant of the ladle's lifespan. Therefore, it is necessary to repair, demolish, and replace it according to its usage.

[0003] During replacement, mechanical tools are required for demolition. Whether the refractory material is high-aluminum brick, clay brick, carbon brick, or aluminosilicate heat-resistant fiber, a large amount of smoke and dust will be instantly generated during the demolition process. This part of the smoke and dust has a low temperature, a slow flow rate, but a high dust content, which seriously pollutes the worker's operation position and also pollutes the environment when it spills into the atmosphere. In addition, a large amount of dust will also be generated during spraying, mud mixing, and masonry, polluting the surrounding environment, affecting the health of workers, and not meeting the control requirements of the environmental protection department for unorganized waste gas emissions.

[0004] The existing technology has the following problems: (1) Most steel mills directly lie the ladle horizontally on the bracket and use a crawler-type ladle dismantling machine for demolition, which will generate a large amount of industrial waste and there is no dust removal facility, resulting in a poor working environment; (2) For the waste such as steel slag and refractory materials removed, they are generally loaded manually directly without a dust removal facility; (3) During masonry operations, there is a lack of facilities for capturing dust, the working environment is poor, the labor intensity is high, and it causes harm to the human body.
