Description

Device for avoiding ladle cover from falling to ground

Technical Field

The utility model relates to the technical field of ladle capping, in particular to a device for preventing ladle caps from falling to the ground.

Background

In recent years, how to improve the smelting level, reduce the energy consumption and reduce the production cost has become an important research topic for iron and steel enterprises. In the steelmaking process, the temperature of molten steel is used as an important technical index and process parameter in steelmaking and continuous casting processes, and has important influence on the steelmaking production level and the casting blank quality. Studies have shown that there are two main ways of heat loss in molten steel: firstly, heat conduction between molten steel and refractory; and secondly, the top of the ladle is opened, and the molten steel radiates heat in the air. Under normal conditions, the temperature of the ladle lining before the steel ladle is filled with molten steel is about 1100 ℃, and is far lower than the temperature of the molten steel, after the molten steel is injected into the steel ladle and contacted with the ladle lining, the temperature of the ladle lining is close to the temperature of the molten steel through heat conduction, and is usually about 1500 ℃, so that the temperature of the molten steel is greatly reduced, the tapping temperature of a converter can be artificially increased in the steelmaking process, and the tapping temperature of the converter is usually about 1650-1700 ℃ and is far higher than the pouring temperature of the molten steel. The tapping temperature of the converter molten steel is closely related to the quality of a casting blank, and the higher the tapping temperature is, the higher the oxygen content in the steel is, so that the yield of the alloy is reduced in the tapping deoxidization alloying process, and meanwhile, inclusions in the steel are greatly increased; on the other hand, taking a 150 ton ladle as an example, the heat radiation of the ladle lining to the air 5 minutes before the empty ladle is not filled with molten steel after baking is most serious, and the heat radiation loss accounts for about 40%, and the heat loss causes the temperature loss of the molten steel in the next furnace to be 10-15 ℃.

The ladle capping technology can effectively block heat exchange between molten steel and air, and the ladle capping device is used for capping the ladle on the ladle, so that the temperature of the blank ladle is kept, heat radiation loss is obviously reduced, the tapping temperature of a converter is reduced, inclusions in steel are reduced, casting blank quality is improved, off-line baking time of the ladle is shortened, molten steel heat insulating agent is saved, gas consumption is reduced, the service life of the ladle refractory is prolonged, and the energy saving and consumption reduction effects in a steelmaking link are particularly obvious.

However, the following disadvantages are found during the production process: under the condition of steel ladle residual steel (slag), the steel slag needs to be turned into a slag pot, in the process, due to the influence of factors such as overlarge turning angle, incorrect steel ladle cover position and the like, the steel ladle cover is easy to fall to the ground, the steel ladle cover is of a steel structure and an internal refractory structure, the steel ladle cover is easy to be damaged and deformed and even damaged after falling to the ground, the steel structure needs to be restored again, the refractory is rebuilt, and the steel ladle cover falls to the ground to threaten the personal safety of operators and also cause the damage of equipment and facilities.
