The calcium aluminate cements CA50-A600 A700 A900, and high alumina castable refractory cement. Generally there are 4 grades of refractory cement according to Al2O3 content and strength, A600, A700,A900 and CA-70.
The ratio of fast setting phase Ca and slow setting phase Ca 2 in the refractory cement produced by CH refractory material is moderate, setting and hardening speed is appropriate, and the performance is stable. And wear resistance, spalling resistance, reducing medium corrosion ability is strong, suitable for cementing material or preparation in high temperature, high pressure and reduction conditions used in the shape of refractories.
CH Refractories with 500T manufacturing capacity of High Alumina Refractory Cement one day to make sure delivery to customers in time. The refractory aluminum cement will be packaged into three layers 25 kg bag and then into two layers moistureproof polytene jumbo bags directly from the manufacturing line to protect high temp refractory cement from wet air.
As professional manufacturer and company of refractory aluminate cement since 1980, CH refractories company produces and provides customers with a varied range of high-tech calcium aluminate solutions benefiting from the highest performance and quality. The SECAR range offers a large choice of binders based on calcium aluminate technology for fire proof applications. Through its understanding of the customer's needs, CH refractories company has developed one of the widest ranges of aluminate cement for sale on the market.
The calcium aluminate cements CA50-A600 A700 A900 manufactured by CH Refractories with stable quality and best price. The cement are exported to many countries regularly, such as Saudi, Malaysia, Indonesia and so on. We are waiting for long term cooperation with you.
