Calcium Aluminate Refractory Cement

High Quality Calcium Aluminate Cement From RS Group

 

 

High alumina refractory cement is made of high alumina bauxite and high purity limestone and then burned into cement through a large rotary kiln. Dipping, and finished by grinding, homogenization and other processes.

High Strength Refractory Calcium Aluminate Cement 0

High alumina cement has excellent early strength, a wide range of application, and stable setting time, making it the first choice for refractory castables.

The raw materials of calcium aluminate cement CA-70/80 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.
