The vacuum ladle is a turnover equipment commonly used in nonferrous metallurgy industry, especially electrolytic aluminium industry, and is a large sealed container made of steel shell lining refractory material, and a certain vacuum degree is generated in the ladle by a negative pressure generating device arranged on the container, so that smelted liquid aluminium and other metals are pumped out of an electrolytic bath and transported to other places. As the high-temperature liquid metal is transported, the lining of the vacuum ladle needs to be built with refractory materials so as to protect the metal material of the ladle body from being melted and thermally corroded and ensure that the internal temperature is not reduced rapidly to cause the solidification of the liquid metal. The masonry of the refractory material layer has two types: the first type is refractory brick masonry, the ladle bottom is tiled by flat bricks, the inner wall is built by arc-shaped bricks with corresponding radians, and the pouring opening is molded by pouring materials. The second type is that the whole material is cast and molded by adopting casting material, and the casting process needs to be assisted by a mold and tamped by a vibrating rod. The two types of refractory materials are high-alumina refractory materials, and the refractory layer after the whole masonry is high temperature resistant not less than 1580 ℃. Generally, the service life of the two-man ladle refractory is generally half a year to one year. However, in the process of sucking the electrolytic aluminum into the ladle from the aluminum suction pipe, because the position of the aluminum suction pipe is unchanged, the high-temperature aluminum liquid sucked out of the aluminum suction pipe flushes the part corresponding to the aluminum suction pipe in the ladle for a long time to form a flushing area, so that the flushing area becomes the easiest and foremost damaged part in the ladle, and other parts of the ladle usually have long service life at the moment, and finally the waste of the heat insulation material of the fire-resistant layer is caused.

The new vacuum ladle and the vacuum ladle after overhaul are thoroughly dried before use, but the existing heating device uses materials such as wood and the like to burn in the ladle to dry the ladle, and then the ladle is heated and dried by using an effect rod or a stub block by an electrolytic plant.
