Description

Technical Field

[0001] The present invention relates to the technical field of slag removal devices, and more specifically, to an automatic slag removal device for a molten iron tank used in a desulfurization station and a method for using the device. Background Art

[0002] There are two main types of molten iron ladle: open molten iron ladle and torpedo molten iron ladle (referred to as torpedo car, mixing iron car). Molten iron ladle is a traditional equipment for transporting molten iron and is widely used. The capacity of a mixing iron car is generally 100-150t, and a large mixing iron car can hold 400-600t of molten iron. Under certain protective conditions, the mixing iron car can transport molten iron to a place tens of kilometers away, and the temperature of the molten iron is less reduced, which can save energy.

[0003] During the desulfurization process in steel mills, a lot of waste slag is produced in the molten iron tank. If it is not removed in time, it may affect the quality of steel. However, most of the existing slag removal equipment is complex in structure and expensive, while simpler slag removal tools require manual slag removal, which is very dangerous. Summary of the invention

[0004] 1. Technical problem to be solved by the invention

[0005] In view of the defects and shortcomings of the prior art, the present invention provides an automatic slag skimming device for a molten iron ladle used in a desulfurization station and a method for using the same. The present invention drives the overall displacement of the slag skimming plate by a moving rod. When the slag skimming plate enters the molten iron ladle and contacts the molten iron, the movable cover flips up, and the waste slag flows into the slag skimming plate from the notch. During the upward movement of the slag skimming plate, the movable cover closes. When the molten iron ladle leaves the molten iron ladle, the molten iron flows out from the second notch on the side of the slag skimming plate, and the waste slag remains in the slag skimming plate, thereby achieving the purpose of filtering the waste slag in the molten iron ladle. The device as a whole has high practicality and strong applicability, can be appropriately adjusted according to the height of the molten iron ladle, and has strong stability and excellent safety during operation.
