Al2o3 High Alumina Refractory Castable Material Powder Thermal Shock Resistance
Thermal Shock Resistance low cement castable refractory material castable refractory cement
low cement castable refractory material
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.
