Description

Technical Field

[0001] The utility model relates to the technical field of ladle hot repair, in particular to a device for cleaning slag along the edge of a ladle. Background Art

[0002] Ladle generally refers to a steel ladle, which is used in steel mills or foundries to receive molten steel for pouring operations in front of open-hearth furnaces, electric furnaces or converters. The ladle is mainly composed of three parts: the outer shell, the inner lining and the injection control mechanism. When using the ladle for smelting, due to the violent stirring and turning of the molten steel and the slag on the surface, the heat of the molten steel is lost, and part of the slag will adhere to the edge of the ladle. After the ladle pouring molten steel is completed, there will be residual slag left at the edge of the ladle, which seriously affects the normal progress of subsequent production. The long-term accumulation of slag at the edge of the ladle may even shorten the service life of the ladle.

[0003] In order to ensure the normal production and operation of the ladle, the slag is removed with the help of external force. The prior art discloses a ladle cover slag removal device with application number: 201710112978.0, which includes a bracket, a maintenance platform, a winch, an inclined base, a ladle fixing seat, and a slag removal vehicle; the top of the bracket is provided with an inclined base, and a winch is provided on the inclined base, and the winch is used to pull up the ladle cover; the top of the bracket is also provided with a maintenance platform, and the maintenance platform and the inclined base are in the same plane for the maintenance of the winch; the ladle fixing seat is used to fix the ladle; the slag removal vehicle is used for slag removal, and the heat loss caused by the molten steel in the process of receiving and conveying is effectively reduced through the ladle cover. However, the device requires the ladle to be placed on the ground, and the slag is removed with the help of the slag removal vehicle, and then the ladle is hoisted back, which is cumbersome to operate, and the cleaned slag is easy to fall into the ladle, and the ladle needs to be turned over to completely remove it, and the on-site slag is further collected and processed, which is labor-intensive, time-consuming and labor-intensive, and greatly reduces the work efficiency.
