Description

Ultra Purity Sintered Corundum Refractory Fire Bricks For Electronics And Petrochemical Furnaces

Alumina hollow sphere is a new kind of high temperature heat insulation material, it is made of industrial alumina in electric furnace melting and blowing, crystal type A-AI203 microcrystal. Alumina hollow ball as the main body, can be made into various shapes of products, the highest use temperature of 1800℃, the product mechanical strength is high, several times of the general light products, and the bulk density is only half of corundum products. It has been widely used in high temperature and ultra-high temperature kilns such as gasifier in petrochemical industry, carbon black industrial reactor and induction furnace in metallurgical industry, and has achieved very satisfactory energy-saving effect. Alumina hollow ball firebrick is made of alumina hollow ball and aluminum oxide powder as the main raw materials, combined with other bonding agents, after 1750 degrees high temperature firing. It is a kind of energy-saving insulation material of ultra-high temperature material.For reducing the weight of the furnace body, reforming the structure, saving materials and saving energy, it will achieve obvious results.
