Low Creep Andalusite Brick / Andalusite Refractory Brick For Hot Blast Stove And Coke Oven
Description of Low Creep Andalusite Brick:
Andalusite bricks are a type of refractory brick known for their exceptional high-temperature resistance and excellent thermal shock resistance. They are primarily composed of andalusite, a naturally occurring mineral with a unique crystal structure that imparts outstanding refractory properties.
1.Features and applications of andalusite bricks:
2.High Heat Resistance
3.Excellent Thermal Shock Resistance:
4.Chemical Inertness:
5.Abrasion Resistance
Common Applications:
Andalusite bricks find applications in industries like metallurgy, ceramics, glass, cement, and other high-temperature processes. They are commonly used in areas of furnaces, kilns, and other high-temperature equipment.
Grades and Specifications:
Andalusite bricks are available in various grades and specifications, tailored to different temperature ranges and specific application requirements. These may include different compositions or additives to enhance certain properties.
