The Cement refractory cement 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 heat resistance cement can be used for making refractory castable and other high temperature resistant products.
CH Refractories with 500T manufacturing capacity of Cement
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.
Cement refractory cement manufactured by CH Refractories are exporting to many countries regulay, such as Malaysia, Saudi, Pakistan, Indonesia and so on. We provide the best price for you base on stable quality.

Applications of Cement refractory cement:
High alumina cement is mainly used to configure refractory castable
such as high alumina low cement castable which can build or repair
furnace or kiln for heat insulation or high temperature erosion.
Also can be used as high temperature resistant cement directly in
high temperature furnrace and kiln. With high strength and
refractoriness
