Insulating Castable Refractory Castable Mullite Insulating Castavble for Fire Hole
Insulating Castable Refractory Castable Mullite Insulating Castavble for Fire Hole
Light weight thermal insulation refractory castable is made of high quality, high strength material as aggregate, superfine powder and composite additive. With high refractoriness, high strength, low thermal conductivity, thermal insulation castable has the advantages of low density, low thermal conductivity, which can reduce the thermal energy consumption of industrial furnace, but also can reduce the weight of the lining.
