High Alumina Bubble Heat Insulating Bricks, Bubble K23 Insulating
Refractory Brick, Industrial Soft Fire Brick
Introduction of High Alumina Bubble Brick:
High alumina bubble brick is made of alumina hollow ball as raw
material, high-performance powder as additive, and organic material
as the temporary binding agent, after mixing, drying, forming,
firing at high temperature in shuttle kiln, the whole process is
Features of High Alumina Bubble Brick:
- Excellent thermal shock resistance, low thermal conductivity and
good performance of insulation.
- High temperature resistance as Al2O3 content is≥85%.
- Reduce furnace weight as there are amount of closed pores in
alumina bubble brick.
- Strong ability to resist erosion of gas and slag.
- Direct contact with flame.
