[0002] Casting paint is a special paint specially used in the casting industry, which is composed of refractory powder, carrier liquid, suspending agent, binder and other components. It is mainly used to cover the surface of the casting core to improve its fire resistance, chemical stability and resistance to metal liquid scouring. The casting paint can be made into slurry, paste or powder, and is applied to the surface of the mold by spraying, brushing, dipping and other methods. Its main function is to form a protective film to prevent adhesion and corrosion between the casting and the mold, and to improve the surface finish and precision of the casting.

[0003] The slurry paint produced is generally filtered through a filter screen. The slurry paint relies on its own gravity to pass through the filter screen, and the filtering speed is slow.
