China Slag Resistance Wear Resistance Series Castable, Find details about China Refractory, Castable from Slag Resistance Wear Resistance Series Castable
Refractory castable is a mixture composed of refractory aggregate, powder and binder. After adding water or other liquids, it is suitable for construction by casting and vibration method, and can also be made into prefabricated parts with prescribed shape and size in advance, which can be used to construct the lining of industrial furnace.The refractory castable has certain setting and hardening time after construction, so after casting and forming, it can be demoulded after a certain time of curing, and then it can be put into baking after a proper time of natural curing.
Refractory castable site construction is convenient, high efficiency, good quality, and can be used according to different parts and conditions of the use of excellent performance of the material.Therefore, refractory castable is a kind of amorphous refractory material with large dosage and wide application scope in furnace building engineering.
The refractory castable is widely used in building materials industry (cement kiln), petrochemical industry, electric power industry, metallurgy industry, non-ferrous metal and its high temperature kiln with similar working conditions.
