Refractory Castables for Sale

Kerui refractory castables are made of refractory aggregate, refractory powder, binder, and other additives, and can be used directly or by adding the appropriate amount of water or other liquids. Once cast or gunned into place, the castable material hardens and cures to form a solid and durable refractory lining. Refractory castables can be installed using different methods depending on the specific application and equipment. Such as casting, gunning, troweling, and pumping.

Classifications of Refractory Castable

Suitable for use in neutral or acidic atmospheres in various high-temperature (generally less than 1350°C) industrial kilns. It is easy to construct and can replace a large number of special-shaped bricks during construction.
Suitable for lining various heat treatment furnaces, heating furnaces, shaft kilns, rotary kilns, electric furnace covers, blast furnace tapholes, etc.; self-flowing low cement castables are suitable for integral spray gun linings for spray metallurgy and petrochemical catalytic cracking reactors. High-temperature wear-resistant linings, outer linings of water-cooled pipes in heating furnaces, etc.
Widely used in high-temperature equipment in metallurgy, chemical industry, electric power, glass and other industries. For example, it is used for the lining, furnace door, furnace and other parts of high-temperature kilns; for the lining of refractory pipes and containers, and for the pouring of refractory insulation layers. In addition, silicon carbide castables can also be used to prepare refractory ceramic products, such as refractory bricks, refractory boards, etc.
