Product Description

Refractory castable is a granulated and powdery material made by adding a certain amount of binder to refractory aggregate. It has high fluidity and is shaped by casting. The castable binder produced by our company has high moisture content, good fluidity, high strength and corrosion resistance, and can be selected according to the conditions of use. It can be directly poured into the lining body, and can be made into prefabricated blocks by pouring or shaking. It is mainly used for the lining parts of various industrial kilns such as incinerators and non-ferrous metal smelting furnaces.
Features Of Refractory Castable

High refractoriness, High refractoriness under load
