Refractory Castable

Castable is a kind of refractory aggregate, powder, binder and admixture according to a certain proportion of preparation, adding water or other liquid mixing, using casting, vibration and other methods of construction of amorphous refractory material.

Convenient construction, good integrity, strong adaptability, short production cycle,

Widely used in metallurgy, building materials, electric power, chemical and other industries of kiln, boiler, heat exchanger and other thermal equipment lining. Such as the iron ditch of the blast furnace, the lining of the steel converter, the transition zone of the cement rotary kiln and other parts.
