High Alumina Refractory Dense Castable Refractory High Temperature Castable Refractory
Refractory castable is one of the unshaped refractory materials.It is made of refractory aggregate . refractory powder . binders and other additives. It is loose, No fixed shape,Has high liquidity, Casting and vibration molding,Can use directly or use after add appropriate water or other liquid. It is one of the new type refractory material of don't need calcination.
Construction way:casting+vibration moulding
Characteristics:
