Description

Technical Field

[0001] The utility model relates to the technical field of steel ladles, in particular to an electro-hydraulic push rod driven steel ladle cover adding and removing device. Background Art

[0002] The ladle is an important equipment used in the steel production process. It is mainly used to carry and transport molten steel. The internal structure of the ladle is usually made of refractory materials, which can withstand high temperature and erosion by molten steel. In the steel production process, the ladle plays a key role in connecting the steelmaking and continuous casting links. First, in the steelmaking process, after the molten steel is refined, the temperature needs to be reduced to a suitable range for subsequent continuous casting operations. At this time, the ladle assumes the task of transporting the molten steel from the steelmaking furnace to the continuous casting machine. Secondly, before the continuous casting machine, the ladle needs to further homogenize the temperature of the molten steel to ensure the smooth progress of the continuous casting process.

[0003] In the field of steel manufacturing, ladle is a key equipment for carrying and conveying molten steel to continuous casting machine. In the traditional ladle design, the setting of liquid guide bucket is to realize the rapid pouring of molten steel. However, the opening of liquid guide bucket makes it impossible to effectively seal the top of ladle, thus causing the molten steel to cool prematurely, which not only reduces the performance of the material, but also has an adverse effect on production efficiency and safety. In addition, the existing ladle cover installation procedure is cumbersome and requires more time and manpower to complete the covering, which not only increases the production cost, but also reduces the convenience of operation.

The cover mechanism 5 also includes a heat-insulating bin 506, a second electro-hydraulic push rod body 507, a sealing block 508 and a drainage groove 509. The middle part of the cover body 504 is fixedly installed with a heat-insulating bin 506, and the interior of the heat-insulating bin 506 is fixedly installed with a second electro-hydraulic push rod body 507.

[0031] The working principle of the utility model is as follows: the electro-hydraulic push rod driven steel ladle covering and removing device is additionally provided with a cover mechanism 5 and a supporting mechanism 6.

When using the electro-hydraulic push rod driven steel ladle covering and removing device, the molten steel is first placed in the steel ladle body 1, followed by the sealing operation, the cover mechanism 5 is enabled, the first electro-hydraulic push rod body 501 is started to press down the connecting pressure plate 502 and the pressing column 503, the three groups of connecting pressure plates 502 and the pressing column 503 press down the cover body 504 evenly, so that the ceramic sealing pad 505 at the lower end of the cover body 504 is tightly fitted to the upper surface of the steel ladle body 1, thereby achieving the sealing effect of the cover. During use, the sealing effect can ensure that the temperature of the molten steel will not drop rapidly. If it is necessary to dump The molten steel can be poured out by activating the cover mechanism 5, starting the second electro-hydraulic push rod body 507 to pull the sealing block 508 backwards, so that the sealing block 508 no longer blocks the drainage groove 509. In addition, the cover body 504 can be opened to directly pour the molten steel. However, in this case, the poured molten steel flows through a large area and protective operations need to be performed. In summary, the cover mechanism 5 and the support mechanism 6 complement each other. The support mechanism 6 is mounted on the supporting ring 4 to support the entire cover mechanism 5. The cover mechanism 5 adopts an electro-hydraulic push rod driving structure to achieve the effect of automatically displacing the cover body 504, making the adjustment operation of the cover body 504 simpler and faster, and a new drainage structure is also added to the cover mechanism 5 to effectively avoid the heat leakage of the traditional liquid guide bucket and ensure the thermal insulation of the cover seal.
