Alumina hollow ball bricks are a new insulating refractory product taking alumina hollow ball as the main raw material. These bricks are mainly used in high-temperature industrial kilns (＜ 1800 °C ) and insulation equipment for the lining and insulation layers.

Production methods of alumina bubble brick: Add raw aluminum into furnace melted liquid, then pour furnace to make the solution flowing out at set speed, so that the flowing stream form 60 ° -90 °flat nozzle. Blown by high-speed air at pressure 0.6-0.8MPa to form alumina hollow ball. According to a certain proportion, batch hollow ball alumina with sintered alumina powder and binder, Then processed by forming, drying, calcining to obtain alumina bubble brick.
Alumina hollow ball has significant insulation properties, low thermal conductivity, which has a very good insulation effect, reduce heat dissipation, improve thermal efficiency, and thus saving energy up to 30%.
