Low cement refractory castable made by CH Refractories with three levels, which are high aluminum low cement castable, mullite low cement castable and corundum low cement castable. The low cement fireproof castable is mainly used for cement kiln masonryespecially for kiln mouth, kiln door cover, cooler, tertiary air duct and coal injection pipe.
Applications of Corundum Castable:
Steel furnace, cement kiln, glass kiln, iron making furnace, ceramic tunnel kiln and so on.

Recirculating fluidized bed boiler
Chemical industry and construction industry
Tundish lining
Advantages of low cement castable refractory material :
Higher strength than common castable
Made from high quality raw material
Excellent strength at various temperatures
Good thermal shock resistance
Packages of castable
The package is designed to protect castable from humidity. However, as with all hydraulic binders, it is recommended that castable not be placed outdoors or in direct contact with the ground. When correctly stored in dry conditions, the properties of castable will remain within specification limit for at least 6 months. In most cases, its properties will be retained for over a year.
