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. Refractory castable is primarily used for furnaces and kilns in metallurgy, petroleum, chemical industry, construction, electric power and machine building.
