Corundum & Mullite Refractory Compound Preformed Block
The rotary kiln body works under High-speed heat flow erosion and dynamic pellets abrasion, and the low-melting materials erosion, the work condition is extremely rigorous for refractory materials.
Our Corundum & Mullite Castables have high thermal strength, good resistance to corrosion
and wearing, all these properties meet the kiln working conditions with long work life.
