Product Description

high performance high alumina castable low cement refractory insulating castable for cement kilns

 

Product Description

High Alumina Refractory Castable is an indeterminate refractory castable with an overall aluminum content of more than 75% composed of high-aluminum aggregate with a content of aluminum oxide greater than 75% as a granular raw material, combined with high-aluminum powder and additives. After the initial setting, the standard curing to 28 days, the compressive strength can reach 40--60MPa.

 
The High Alumina Refractory Castable combines the characteristics of traditional refractory materials and adopts the most advanced ultra-fine powder application technology, which highlights the improvement of the high-temperature volume stability of the castable, so that the organizational structure of the product forms a firm anchor-like multi-directional crystal structure at high temperature. The overall structural stability of the lining body is ensured, and the service life is 2--3 times longer than that of traditional castables.
