Problems solved by technology

[0003] At present, the ladle uncovering and capping equipment in many steel mills is a gear-shaped structure. This structure has high requirements on the space size of the production site, and it is impossible to realize the whole process of capping in the true sense. In addition, once the gear-shaped structure equipment fails, it will Immediate production stoppage accident
This problem has not been effectively solved so far, and it has become a difficult problem that has plagued design technicians and steel mill technicians for a long time, and it needs to be solved urgently

Abstract

The invention discloses a device and method capable of conducting whole-process capping and decapping on a steel ladle and belongs to steel ladle capping and decapping equipment and method. The device and method capable of conducting whole-process capping and decapping on the steel ladle are used for conducting capping and decapping operation on the steel ladle. According to the technical scheme, a body of an electric-hydraulic push rod is connected with a support; the front portion of the electric-hydraulic push rod is connected with a moving trolley; a rail is mounted on a platform on the upper portion of a workshop; the moving trolley is located on the rail; a winding device is mounted on the moving trolley; the lower portion of the winding device is connected with a cap hoisting; and the cap hoisting is detachably connected with a cap. By means of the moving trolley, the rail and the electric-hydraulic push rod of the device, the cover hoisting can be moved to the hoisting position of the cap; by means of the winding device, the cap hoisting tool is ascended and descended; and the tasks of mounting and removing the cap are completed. The steel ladle capping and decapping device is compact in structure, small in occupied space, steady and reliably in operation and particularly applicable to rebuilding and upgrading of a steel mill; and after rebuilding, the original technological arrangement structure is not affected. The steel ladle capping and decapping method is convenient and fast to use, operation time is saved, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to a device and method for taking up less space and enabling ladles to be uncapped throughout the process, and belongs to the technical field of ladle uncapping equipment and methods. Background technique [0002] The temperature in the ladle running state directly affects the smelting process operation and the metallurgical quality of molten steel. Aiming at the problem of large fluctuations in molten steel temperature during the steelmaking process, measures such as strengthening ladle baking, improving ladle heat turnover, optimizing the ladle lining structure, adding heat insulating agent during molten steel operation, and covering the ladle during pouring are generally adopted to reduce the cooling of molten steel. . In the above methods, the role of ladle capping is obvious. Research shows that after a 150t ladle is empty, the radiation heat loss from the lining to the air in the first 20 minutes will cause the temperature ...
