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.
