Product Details

Low creep and high strength Andalusite refractory brick for flue wall

 

Andalusite Refractory Brick has a number of advantades, high creep resistance is the standard to measure capacity of refractory brick's long term resistance to high temperature.

 

Andalusite Refractory Brick contains little impurities,and the strength under high temperatuer decreases little with temperature rises which is another notable feature of the brick.


Fratures:

Low creep

High strength

Volume stability
Good slag resistance

Good thermal shock resistance

 

Application:Andalusite Refractory Brick is widely used in flue wall of carbon baking furnace.
