Customized Low creep 2.35g/cm3 Andalusite fire proof brick for fire wall
Low creep Andalusite Fire Proof 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.
Low creep Andalusite Fire Proof Brick Fratures:
Low creep
High strength
Volume stability
Good slag resistance
High cold crushing strength
Good thermal shock resistance
Low creep Andalusite Fire Proof Brick Application:Andalusite Fire Proof Brick is widely used in flue wall of carbon baking furnace, cooling wall of blast furnace, chemical and ceramic industry, the door of coke oven, or as the lining and checker of hot blast furnaces.
