Description

Repairing device and repairing method for ladle opening Technical Field The invention relates to the technical field of steel smelting equipment, in particular to a repairing device and a repairing method for a ladle opening. Background The ladle is an important device for continuous casting, and is a container for carrying and holding molten steel in the process from tapping to pouring. The molten steel in the ladle has high temperature and long residence time, and argon blowing treatment and secondary refining are sometimes performed. The damage factor of the lining of the steel ladle is many, the actions of different brick types at different parts of the steel ladle are different, and the damage condition is also different. At the position of the ladle slag line, the erosion capability of the high-temperature slag on refractory materials exceeds the erosion damage of molten steel on brick linings. The ladle wall and other parts are lighter in erosion effect by slag and molten steel than slag line parts at high temperature, and generally only bear the scouring and abrasion effect of molten steel. When receiving molten steel, the ladle bottom is subjected to mechanical scouring and strong mechanical impact of the molten steel, and is easy to peel off and damage from an interface of a modified layer. Because the high-temperature slag at the slag line part is eroded and damaged, the high-temperature slag line part is repeatedly subjected to frequent repeated and repeated use of the high-temperature cooling effect and the mechanical damage of the anchor hook during cleaning is included, the refractory material at the ladle opening part is extremely easy to damage, the refractory material consumption is increased, the repairing is usually carried out in a manual mode at present, the repairing efficiency is lower, the repairing effect is poorer, and the service life of the ladle is further influenced. Disclosure of Invention Aiming at the problems that the repairing efficiency is low, the repairing effect is poor and the service life of the steel ladle is reduced due to the fact that the repairing engineering quantity is large and the repairing efficiency is low when the steel ladle mouth is repaired manually at present, the invention provides a repairing device and a repairing method for the steel ladle mouth.
