Shengyuan Refractory-[Alumina Hollow Ball] Product specifications: 3-5mm / 1-2mm / 2-3mm / 0.2-1mm / 0.2-0.5mm Product introduction: Alumina hollow balls are a new type of high-temperature insulation material. They are made of industrial alumina smelted and blown in an electric furnace. The crystal form is a-Al2O3 microcrystals. Using alumina hollow balls as the main body, it can be made into products of various shapes. The maximum operating temperature is 1800°C. The mechanical strength of the products is high, several times that of ordinary lightweight products, and the volume density is only one-half of corundum products. Product application: It has been widely used in high-temperature and ultra-high-temperature kilns such as gasifiers in the petrochemical industry, carbon black industrial reactors, and induction furnaces in the metallurgical industry, and has achieved very satisfactory energy-saving effects.
