Description
1.Refractory castable Description
Refractory castable is one of the unshaped refractory materials, which is made of refractory aggregate, refractory powder, binder and other additives. Refractory castables are loose, irregular, high fluidity, casting, vibration molding, and can be used directly or after adding water or other liquids.
