　　Chromium zirconium corundum brick uses corundum as the main raw material, introduces a small amount of industrial-grade chromium trioxide, zircon sand, and a binder in a certain proportion. After high pressure molding, it is fired at high temperature with high softness, high strength and corrosion resistance Good composite refractory products. Mainly used in municipal solid waste incinerators, industrial waste incinerators, medical waste incinerators, ordinary solid waste incinerators, hazardous waste incinerators, etc.
