Alumina Bubble Brick

Alumina bubble brick is based on the alumina hollow ball and alumina powder as the main raw material, mixing with other binders by sintering at 1750 degrees high temperature. It’s a kind of new type high temperature thermal insulation materials, max working temperature can reach to 1800℃， meanwhile it’s mechanical strength is 3 times of common insulation bricks.

1.High temperature resistance:Up to 1750 degrees or more, good thermal stability.

2.Reheat line change rate is small, service life is longer.

3.Effectively reducing the furnace weight saving materials cost.

4.Saving energy:Alumina bubble has obvious insulation properties, low thermal conductivity, saving energy up to 30% or more.

Alumina bubble brick is widely used in petrochemical industry gasification furnace, carbon black industry reaction furnace, metallurgical industry induction furnace and other high temperature, ultra-high temperature kilns, and achieved very good energy-saving effect.
