Refractory Castable: It is our bestseller. We can supply many kinds of refractory castable, such as low cement castable, self flowing castable, high alumina castable, mullite castable, AZS castable, fireclay castable, light weight refractory castable etc.
The refractory castable is unshaped refractory material that doesn't need firing and features fluidness after adding water. Mixed by grain, fines, and binder in fixed proportion, refractory castable can replace special shaped refractory material. Refractory castable can be used directly without firing, easy to construct, and has a high utilization rate and high cold crushing strength.
The refractory castable is primarily used fro furnaces and kilns in metallurgy, petroleum, chemical industry, construction, electric power and building etc.
