Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking equipment, in particular to a slag basin for a ladle car under a steelmaking furnace. Background Art

[0002] The so-called ladle car under the steelmaking furnace generally refers to the ladle transfer rail flat car, which is a special-purpose electric flat car. It is generally used by factories to transfer specific high-temperature ladles of molten steel. It is a ladle car that uses rails as its running route. Due to the high temperature and safety of the ladle rail car, the flat car body material, transmission system requirements, electrical control requirements, etc. are very different from ordinary rail flat cars. During the use of the ladle car, it is necessary to receive the molten steel, and the tool for receiving the molten steel is the slag basin.

[0003] Patent website publication number CN202465735U discloses an anti-sticking slag basin with an overflow steel trough ramming material coating. When working, an anti-sticking layer formed by the overflow steel trough ramming material is provided on the basin edge, the basin bottom and the inner wall of the basin body, so as to form a good impact resistance layer and barrier layer for the high-temperature molten steel poured from above. However, in the actual process of collecting molten steel, the residual slag inside the slag spray is mixed with the poured molten steel, and steel lumps will be formed after cooling, which will cause trouble to the slag turning work. If the steel lumps are not intervened, the large pieces of steel lumps formed need to be cut before they can be returned to the furnace for smelting, which is more labor-intensive. However, this device does not solve this problem. Utility Model Content
