What Is Alumina Hollow Ball Light Castable

Because of the thin and fragile wall of alumina hollow ball lightweight castable, vibration molding is usually used instead of press molding. After boring, the brick is usually fired at 1500-1800℃ in a high-temperature kiln. Alumina hollow ball products compared with ordinary refractory ball, its characteristics is the product contains a large number of closed muzzle hole, therefore, it not only has good heat insulation performance, but also has strong resistance to corrosive gas and slag. Alumina hollow ball product is a new type of heat insulation refractory material made from alumina hollow ball. Its high strength and stable pore structure enable data to be used at high temperatures. The above products are very suitable for high temperature furnace lining data. Its low density and low thermal conductivity can greatly save fuel.
