High Alumina Insulation Brick

High alumina insulation brick is also known as light weight alumina insulating brick.It is made from bauxite, alumina above 48%, porus structure shaped by foam process and method of EPS ignition loss.

1.High porosity.

2.Low volume density.

3.Good insulation effect.

4.High mechanical intensity.

5.Low thermal conductivity.

It is used for the construction of furnace lining and insulating layer, and the parts without erosion or scouring action of intense high temperature melting material. The surface contact temperature shouldn’t be higher than 1350℃ when it is exposed to flame directly.
