The Al2O3 content of this refractory brick is about 40-80%. It is made of high alumina bauxite and other materials.
The main mineral components are mullite and corundum phases.
Produced by drying pressing and high-temperature firing.
1. High strength
2. High-temperature resistance
3. Good thermal shock resistance
4. Good abrasion and corrosion resistance
5. High refractoriness under load
Kinds of high-temperature industry furnaces.
Glass furnaces, hot blast stoves, cement rotary kilns, smelting furnaces, refining furnaces, tunnel kilns, etc.
