High Temperature Furnace And Kiln Applied Refractory Alkali-Resistant Fire Brick

Refractory Alkali-Resistant Fire Brick

The alkali-resistant firebricks use silica, coke stones and appropriate additives to improve the microstructure of the product. In the process of using, alkali-resistant refractory brick reacts with alkaline oxide to form a high-viscosity glass phase, which covers the surface of the firebrick to block the surface pores, prevents the infiltration of alkaline slag, and to meet the purpose of resisting alkali and resisting corrosion. On the basis of a common type of high-strength alkali-resistant refractory brick, it is produced by adding an additive to increase the compressive strength.

Advantages of Alkali-resistant Brick:
High strength, stable volume
Good alkali corrosion resistance
Customerize mould according to different size requirements for free
