Alumina Bubble Refractory Brick

Alumina bubble refractory brick 1.light weight 2.high service temperature 3.low thermal conductivity.

Alumina bubble refractory brick could be exposed  to the direct flame; it has good insulating property and high cold crushing strength, also is light weight and energy saving.

Applications:

Petrochemical and chemical industry--carbon black furnace, gasifier, ethylene pyrolyzer,  one-stage converter, hydrogen production furnace, etc. 

Ceramic industry--tunnel kiln, flagon kiln, roller kiln, shuttle kiln, bell-type furnace, net-bell tunnel, etc.

Metallurgical industry.
