High purity alumina hollow ball
Alumina hollow ball is a new type of high-temperature insulation material, which is made of industrial alumina melted and blown in an electric furnace, and the crystal type is a-Al2O3 microcrystals. Alumina hollow ball as the main body, can be made into a variety of shapes products, the maximum operating temperature of 1800 ℃, products with high mechanical strength, for the general lightweight products several times, and bulk density is only one-half of corundum products. In the petrochemical industry gasification furnace, carbon black industry reaction furnace, metallurgical industry induction furnace and other high temperature, ultra-high-temperature kiln has been widely used, and achieved very satisfactory energy-saving effect. Alumina hollow ball and its products are a kind of lightweight refractory materials with high temperature resistance and excellent energy saving, which are very stable under various atmospheres. Especially in the 1800 ℃ high temperature kiln applications. Hollow ball can be used as high temperature, ultra-high temperature thermal insulation filler, high temperature refractory concrete lightweight aggregate, high temperature castables, etc.. Hollow ball bricks can be used in high temperature energy saving (>30%) inverted flame kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nitriding furnace and so on. For reducing the weight of the furnace body, remodeling the structure, saving materials, saving energy, will achieve obvious results.
