Product Introduction
Chrome corundum castable is made of fused chromium oxide powder and fused corundum as main raw materials, with high temperature binder and admixture added in a certain proportion. It is a high-grade refractory castable with particularly strong slag and corrosion resistance.
Chrome corundum castable has unique slag resistance and can be made into chrome corundum castable precast bricks. It also has high temperature strength, high thermal shock stability and wear resistance.
Product Advantage
- Chrome corundum castable has unique slag resistance and can be made into chrome corundum castable precast bricks.
- It also has high temperature strength, high thermal shock stability and wear resistance.

Application Field
The castables are mostly used in hazardous waste disposal rotary kilns with harsh working conditions such as the feeding end, discharging end and secondary combustion chamber. They are used in easily worn parts of industrial furnaces, especially in parts with frequent rapid cooling and heating. They can reduce the number of furnace shutdowns and have obvious effects.
