Product introduction of refractory corundum brick
The raw material of refractory corundum brick is a kind of solid solution synthesized by alumina and chromium oxide according to a certain proportion through high temperature melting. The internal quality and high temperature performance of refractory brick can be improved by using special refractory material production technology.
Advantages of refractory corundum brick
- Very good chemical stability
- Good erosion resistance
- It has strong resistance to acid or alkaline slag, metal and glass liquid.
