Description

Technical Field

[0001] The utility model relates to a cover device, in particular to a device which can provide a cover for a ladle on a ladle car for shielding, and belongs to the technical field of ladle car cover equipment. Background Art

[0002] Ladle cars are important transfer equipment in the metallurgical industry. They can transfer ladles from one location to a designated location. During the transfer process of the ladle car, the ladle carries high-temperature molten steel, and the ladle car inevitably changes speed. At this time, the molten steel in the ladle will shake, and some of the molten steel will inevitably splash out. When the ladle is placed on the ladle car, there is no top cover, so the molten steel will splash out of the ladle and fall to the ground on site, which poses a safety hazard along the ladle car and threatens the personal safety of the staff. In addition, during the open transportation of the ladle, the open structure accelerates the dissipation of the heat of the molten steel in the ladle, which is not conducive to subsequent molten steel processing operations. Therefore, it is necessary to set a cover device on the ladle car to prevent the ladle from splashing and reduce heat dissipation. Utility Model Content
