China Fire Resistant High Heat Refractory High Alumina Cement For Boiler

 

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 alumina cement has excellent early strength, a wide range of application, and stable setting time, making it the first choice for refractory castables. High alumina fire cement has many characteristics such as high early strength enhancement, high hydration heat, strong sulfate resistance and high temperature resistance. High alumina cement is applied to the special needs of emergency construction, emergency repair, sulfate resistance and winter construction.

High Alumina Refractory Cement Description

High alumina cement is produced by fusing selected raw material in Special furnace. After cooling, the clinker is ground using ball mills. The raw materials of high alumina refractory cement CA-70 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. The content of Al2O3 is usually controlled within 68% to 72%. The principal compounds of it are CA and CA2.
