Chase CA50-A600/A700/A900 is a large group of aluminate cements owned by Kaifeng Datong Refractories Co.,Ltd. It 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.
Datong aluminate cement has excellent early strength, a wide range of application, and stable setting time, making it the first choice for refractory castables
