Application of Bubble Alumina brick

Bubble Alumina brick is a new kind of high temperature insulation material, it is made of industrial alumina smelting and blowing in the electric furnace, and the crystal form is A-al2o3 microcrystal. Bubble alumina brick as the main body, can be made into a variety of shapes of products, the highest use temperature of 1800℃, products of high mechanical strength, for the general light products several times, and the volume density is only half of corundum products. In the petrochemical industry gasifier, carbon black industrial reactor, metallurgical industry induction furnace and other high temperature, ultra-high temperature kiln has been widely used, has achieved very satisfactory energy-saving effect.
