Alumina bubble bricks is made of industrial oxidation raw material, blown by electric melting at high pressure, combined with -alumina ultrafine powder, high purity AL2O3, and sintered at 1800℃. The refractory product has the advantages of small volume density, small heat capacity, anti-spalling and so on. It is widely used in lining of high-temperature furnace and auvin energy-saving material.
Alumina bubble brick is alumina hollow ball and aluminum oxide powder as the main raw materials, combined with other binder, after 1750 degrees of high temperature fired. Belongs to ultra high temperature material energy - saving heat preservation material. This series of firebrick has obvious thermal insulation characteristics, low thermal conductivity, can play a very good thermal insulation effect, reduce heat emission, improve thermal efficiency, so as to save energy. The energy saving effect can reach more than 30%.
This series of refractory bricks can also be used for high temperature and energy saving flame kiln, shuttle kiln, molybdenum wire furnace, tungsten bar furnace, induction furnace, nitriding furnace and so on. For reducing the weight of furnace body, reforming structure, saving material and energy, obvious effect will be obtained.
It mainly takes alumina bubble as the main body, and can be made into various shaped products. The use temperature is 1800℃. The products have high mechanical strength, several times that of the general light products, and the volume density is only half that of corundum products. It has been widely used in high temperature and ultra-high temperature furnaces such as gasifier for petrochemical industry, carbon black industrial reaction furnace and induction furnace for metallurgical industry.
