Alumina hollow ball is a new type of high temperature heat insulation material, it is the industrial alumina smelting and blowing in the electric furnace, crystal form of a-Al2O3 microcrystal.With alumina hollow ball as the main body, can be made into various shapes of products, the highest operating 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.It is widely used in high and ultra-high temperature kilns such as gasifier in petrochemical industry, carbon black industrial reaction furnace and induction furnace in metallurgical industry, and has achieved very satisfactory energy saving effect.
The advantages of alumina hollow ball as raw material in refractory materials: to reduce the weight of furnace body, transform the structure, save materials, save energy, will achieve obvious results.
1, the use of high temperature: up to 1750 degrees above, good thermal stability.Reburn line change rate is small, longer use.
2, optimize the structure, reduce the weight of the furnace body: now the use of high-temperature resistant materials belong to the heavy brick volume density of 2.6-3.0g/cm, and the alumina hollow ball brick only 1.2~1.6g/cm, the same cubic meter volume, the use of alumina hollow ball brick can reduce the weight of 1.1-1.9 tons.
3, save energy: alumina hollow ball 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%.
