Anti-Spalling High Alumina Brick

Description:

Anti-spalling high alumina brick is a refractory product fired by a high-grade high-alumina bauxite material and zircon sand as raw materials through a high-temperature tunnel kiln. It has strong anti-stripping ability and good resistance to alkali erosion.

Advantage:

Excellent thermal shock stability, high refractoriness under load, excellent high temperature performance

Application:

New dry process cement kiln
