Application:
Cement Refractory Alumina Mortar is a kind of grinding hydraulic cementing materials with clinker about 50% alumina content and has calcium aluminate as the main material, which is also called refractory cement, which can be made to low cement high alumina castable to build or repair all kinds of furnace and kilns for thermal insulation or acid erosion resistance with high strength.
Intruction For Cement Refractory Alumina Mortar :
The raw materials are high purity calcium materials and high pure alumina. The raw materials should be mixed according to suitable ratio. The raw material should be burned to partly fuse. After cooling, α-Al2O3 powder added into clinker, then ground to cement. The content of Al2O3 is usually controlled within 68% to 72%. The principal compounds of it are CA and CA2.
Features For Cement Refractory Alumina Mortar :
Refractoriness under load is high; strength in working temperature is high; resistance to erosion is good. For high purity, it has high erosion resistance to reducing medium such as Co, H2, and CH4.
The early strength and strength in medial temperature of CA-70/80 are both high.
Refractoriness is more than 1650°C.
