Alumina Hollow Ball Brick / Alumina Bubble Brick

Alumina hollow ball brick, also called as Alumina bubble brick, is made of alumina hollow ball and alumina powder as the main raw material, combined with other binding agent. It belongs to one kind of energy-saving and heat preservation material of ultra-high temperature material.

Alumina hollow ball brick's Specification:

Alumina hollow ball brick Features:

1, Use in high temperature:

Up to 1750 degrees above, good thermal stability. The rate of change of re-burning line is small, and it can be used for a longer time.

2, Optimize the structure, reduce the weight of the furnace:

Now with high temperature resistant materials are heavy brick bulk density of 2.6-3.0g/cm, while the alumina hollow ball brick only 1.1 ~ 1.5g/cm, the same cubic meter volume, the use of alumina hollow ball brick can reduce the weight of 1.1-1.9 tons.

3, Material saving:

To achieve the same temperature, such as the use of heavy bricks and alumina hollow ball brick price is comparable, and also requires considerable insulation layer of refractory materials. If the use of alumina hollow ball bricks, each cubic meter can save 1.1-1.9 tons of heavy bricks, but also save 80% of the refractory insulation materials.

4, Save Energy:

Alumina bubble brick has obvious heat preservation characteristics, low thermal conductivity, can play a very good thermal insulation effect, reduce the heat emitted, improve the thermal efficiency, so as to play the purpose of saving energy. Energy saving effect can reach more than 30%.
