2. The method for breaking skull in an RH refining vacuum process as claimed in claim 1, wherein: in the steel ladle jacking operation process, the steel ladle jacking operation is one-way jacking, and the descending operation is not carried out.

Technical Field

The invention relates to the technical field of RH refining, in particular to a method for breaking a slag shell in a RH refining vacuum process.

Background

At present, the molten slag composition in the RH smelting process has the characteristics of high melting temperature, high viscosity and lower fluidity, so that the slag sticking of the dip pipe is easily caused; in addition, because the alkalinity of the slag components is high and the surface heat dissipation is rapid, the slag is easy to crust. If the dip pipe is stuck with slag, the slag is difficult to remove, the continuous processing capacity is greatly weakened, and the like; the crusting affects the operation and easily damages the device, which greatly affects the stability and continuity of the production and increases the maintenance rate and cost of the equipment.
