Rongsheng Group
High alumina refractory castable is a kind of hot sales refractory castable for furnace application in Rongsheng factory manufacturing and is widely used as lining for various kilns such as boilers, blast furnace hot blast stoves, heating furnaces, and ceramic kilns.
Characteristics of high aluminum refractory castables
Refractory high alumina is castable have good properties of compact bulk density, low porosity, and strong resistance to slag or solution penetration. Resistant to rapid cooling, heat shock resistance, and thermal shock resistance.High compressive strength, good wear resistance. Easy to construct, refractory high alumina castable can be cast into a whole lining, or it can be customized into prefabricated masonry. Refractory high alumina castable have chemical resistance.
