The structure is advantaged in that the arc extinguishing capability is improved without increasing the size and the opening distance of the arc extinguishing chamber, and the size of the product is reduced.

The invention relates to a high-temperature protective coating used in the heat treatment process before hot rolling of nickel-based alloy steel. The coating powder part includes the following components: Al 2 o 3 20%-40%, SiO 2 10%-30%, MgO10%-20%, TiO 2 10%-20%, CuO5%-15%, Y 2 O35%-15%, Na 2 O0%-1%, K 2 O0%-1%, where Al 2 o 3 and SiO 2 Derived from one or both of kyanite and aluminum ash; TiO 2 Originated from rutile ore. The binder in the paint is formed by mixing one or more of sodium water glass, potassium water glass, and silica sol; the dispersant is carboxymethyl cellulose. When using, first mix the powder and water in a weight ratio of 2:1 to form a slurry, add a binder, the binder accounts for 5%-10% of the slurry, add a dispersant, and the dispersant accounts for the slurry The mass ratio is 1%-2%. After mixing, ball mill to a particle size of 200-600 mesh to get the coating. It can be sprayed directly under the steel billet below 800 °C, which can effectively solve the difficult removal of nickel-based alloy steel caused by heat treatment at 1200-1350 °C. scale problem.
