Product Introduction:
Corundum mullite brick refers to refractory products made of high-purity or relatively pure raw materials.Products made with mullite granules as aggregate have good thermal shock resistance but poorer erosion resistance. Products made with corundum sand as aggregate have good corrosion resistance.
Features:
1. High strength.
2. Good creep resistance under high temperature.
3. Good erosion resistance.
4. Good thermal shock resistance.
Application:
The corundum mullite brick is mainly used for the superstructure of regenerator of glass furnace and as lining brick of metallurgy kiln,carbon reaction furnace.It can also be used as roof brick,port brick and burner brick.
