Product Description
Alumina hollow ball brick is made of alumina hollow ball and aluminum oxide powder as the main raw materials, combined with other bonding agents, after 1750 degrees of high temperature fired. It is a kind of energy-saving insulation material of ultra-high temperature material. Alumina hollow ball as the main body, can be made into various shapes of products, the highest use temperature of 1800ºC, 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.
Product features:
1. high use temperature:
It can reach more than 1750 degrees and has good thermal stability. Small change rate of heavy burn wire, longer use.
2. optimize the structure, reduce the weight of the furnace body:
Now the high-temperature resistant materials are heavy bricks with a volume density of 2.6-3.0g/cm, while alumina hollow ball bricks are only 1.1-1.5g /cm, the same cubic meter volume, the use of alumina hollow ball bricks can reduce the weight of 1.1-1.9 tons.
3. Save materials:
To achieve the same use temperature, such as the use of heavy brick and alumina hollow brick price is comparable, but also need considerable insulation layer refractory. If the use of alumina hollow ball bricks, per cubic meter can save 1.1-1.9 tons of heavy brick use, but also save 80% of the refractory insulation material.
4. Save energy:
Alumina hollow ball has obvious thermal insulation characteristics, low thermal conductivity, can play a good thermal insulation effect, reduce heat dissipation, improve thermal efficiency, so as to save energy. The energy saving effect can reach more than 30%.
Typical applications:
Widely used in metallurgy, building materials, light industry, chemical industry, ceramics, glass, electronics and other industries. The shape size, physical and chemical index and service life of the products have reached or exceeded the level of similar products at home and abroad.
