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

Background technique

In recent years, how to improve the level of smelting, reduce energy consumption, and reduce production costs has become an important research topic for iron and steel enterprises. In the steelmaking process, the molten steel temperature is an important technical index and process parameter in the steelmaking and continuous casting process, which has an important impact on the production level of steelmaking and the quality of the slab. Studies have shown that there are two main ways for molten steel heat loss: one is heat conduction between molten steel and refractory materials; the other is heat radiation from molten steel to the air due to the opening at the top of the ladle. Under normal conditions, the temperature of the lining before the ladle is filled with molten steel is about 1100°C, which is much lower than the temperature of the molten steel. After the molten steel is injected into the ladle and contacts the lining, the temperature of the lining is close to the temperature of the molten steel through heat conduction, usually around 1500°C. As a result, the temperature of the molten steel drops sharply. In order to prevent the molten steel from solidifying in the ladle, the steelmaking process will artificially increase the tapping temperature of the converter. Usually, the tapping temperature of the converter is around 1650°C to 1700°C, which is much higher than the pouring temperature of the molten steel. The tapping temperature of molten steel in the converter is closely related to the quality of the slab. The higher the tapping temperature, the higher the oxygen content in the steel, which leads to a decrease in the yield of the alloy during the deoxidation alloying process of the tapping, and also leads to On the other hand, taking a 150-ton ladle as an example, the thermal radiation of the ladle lining to the air is the most serious 5 minutes before the empty ladle is filled with molten steel after baking, accounting for about 40% of the heat radiation loss. Heat loss will result in a temperature loss of 10-15°C for the next batch of molten steel.

The ladle capping technology can effectively block the heat exchange between the molten steel and the air. The ladle capping device is used to cover the ladle on the ladle, thereby maintaining the refractory temperature of the empty ladle, significantly reducing heat radiation loss, and reducing the tapping of the converter temperature, reduce inclusions in steel, improve billet quality, shorten ladle off-line baking time, save molten steel heat preservation agent, reduce gas consumption, increase the life of ladle refractory materials, and the effect of energy saving and consumption reduction is particularly significant in the steelmaking process.

However, the following shortcomings were found during the production process: in the case of steel (slag) remaining in the ladle, the steel slag needs to be turned into the slag tank. It is very easy to cause accidents when the ladle cover falls to the ground. The ladle cover is a steel structure and internal refractory material structure. After the ladle cover falls to the ground, it is easily damaged, deformed, or even damaged. Threat to the personal safety of operators, and also cause damage to equipment and facilities.
