Ingot mold coating is divided into two types: mold wall coating and mold bottom coating. It is used to eliminate surface defects of steel ingots and reduce the consumption of steel ingot molds. In the process of ingot production, due to its own defects and the structural bonding of the ingot, the service life of the ingot mold is reduced, and the consumption of the ingot mold is increased; at the same time, the surface quality of the ingot is also affected. As the smelting process intensifies and the speed of casting ingots increases, the impact of such problems becomes more and more serious. One of the ways to solve this kind of problem is to coat a layer of protective coating on the inner surface of the steel ingot mold, that is, steel Ingot mold coating.

Ingot mold coating is a coating agent for the inner surface of the steel ingot mold for the purpose of eliminating the surface defects of the steel ingot and reducing the consumption of the steel ingot mold. When in use, it is evenly sprayed on the inner surface of the steel ingot mold with special spraying equipment. During the pouring process, this layer of coating film can greatly reduce the surface defects of the steel ingot, such as scabbing, overturning, cracks, surface air bubbles and subcutaneous air bubbles. Great inhibition. At the same time, it reduces the phenomenon of steel ingot welding and prevents the molten steel from eroding and scouring the surface of the ingot mold, thereby protecting the steel ingot mold.
