Description

Liquid metal transfer ladle deslagging hot repair machine Technical Field The invention relates to the technical field of metallurgical equipment, in particular to a liquid metal transfer ladle deslagging hot repair machine. Background In the production process of liquid metal in metallurgical industry, after molten steel or molten iron finishes casting operation, the used transfer ladle (such as ladle and ladle) must be subjected to deslagging cleaning and lining hot repair maintenance so as to ensure that the ladle can be repeatedly and safely used and prolong the service life. At present, the operation is finished by being manually matched with a simple overturning device, and a mechanical arm or a hinged support is generally adopted to realize the overturning operation at a limited angle. However, the prior art has the defects that firstly, the posture of a transfer ladle is difficult to continuously and accurately adjust in the overturning process, a reliable arbitrary angle locking mechanism is lacked, the control precision of the residual quantity of the deslagging is low, meanwhile, the ladle body is easy to shake during hot repair operation, the stability and quality of repair operation are seriously affected, secondly, an effective physical isolation measure is generally lacked in an operation area, high Wen Zhaliao splashes and smoke generated along with the splash are difficult to effectively restrict, the safety threat is formed on operators, the operation environment is polluted, and the deslagging and the hot repair are usually completed by two sets of independent equipment respectively, the transfer ladle is required to be transported and repositioned for many times, the operation period is obviously prolonged, the overall efficiency is reduced, and furthermore, the prior equipment is difficult to adjust in terms of high adaptability and positioning precision and poor in universality and is difficult to meet the requirements of modern metallurgical production on efficient, flexible and safe operation. Through the search, an oxidized pellet chain grate machine air-cooled transfer chute with the publication number of CN102538473B is disclosed, and the patent relates to a chute structure for transferring high-temperature materials, and the service life of the chute under the high-temperature working condition is prolonged by arranging a cooling bellows and a heat-resistant steel bolt connection mode. Although the design is optimized in terms of structural strength and heat resistance, the design is of a fixed chute structure, does not have the functions of actively overturning, deslagging or hot repairing the container, cannot realize multi-angle posture adjustment and stable support of the liquid metal transfer ladle, and does not have an integrated hot repairing operation platform, so that the core requirement of deslagging and hot repairing integrated operation cannot be met. Through searching, a full-automatic roller type large steel cylinder heat treatment production line with the publication number of CN114657339B is disclosed, and the patent discloses a sectional type continuous heat treatment production line, wherein automatic transfer of workpieces between a quenching furnace and a tempering furnace is realized through a transverse transfer trolley, and heat loss is reduced by adopting a separate roller set. Although the system realizes the automatic transfer and heat treatment of the high-temperature container, the core function of the system focuses on the heat treatment process, rather than the deslagging cleaning and lining repairing in the empty package state. The production line is not provided with a turnover mechanism, cannot realize large-angle overturning slag pouring, and is not integrated with a positioning, supporting and protecting structure required by hot repair operation, so that the applicability in a maintenance scene of a liquid metal transfer ladle is limited. The problems indicate that a special device integrating efficient deslagging, stable hot repair, safety protection and flexible adaptation is not available in the prior art. Therefore, the invention provides a liquid metal transfer ladle deslagging hot repair machine, which aims to solve the defects of the prior art in the aspects of functional integration level, operation safety and operation efficiency by a large-angle stepless turnover mechanism, an arbitrary position locking device, an integrated hot repair platform and a slag dust isolation system, and provides an efficient, intelligent and safe transfer ladle maintenance solution for the metallurgical industry.
