Product Details


Characters of Low Creep High Alumina Brick

 

Low creep high alumina brick products use superfine grade bauxite clinker as main raw material, supplemented by special additive, via high pressure molding, high temperature firing. It has great capacity of heat storage, and the advantages of small creep rate which is suitable for middle and small blast furnace hot blast stove.

 

Applications of Low Creep High Alumina Brick

 

Low Creep High Alumina Brick Wildly used in blast furnaces, hot air stoves, the blast furnace, hot blast stove regenerative chamber walls and grid, combustion chamber, mix the wind chamber and contact pipe and all kinds of unburned brick nozzle.
