Andalusite Brick
Andalusite brick use burnt gemstones and andalusite as raw materials, and first-grade rocky soil and andalusite as fine powder to make andalusite bricks with good performance. It has high cold crushing strength,high refractoriness under load, high thermal stability,good creep resistance and thermal shock resistance,It is alternative product for high aluminum bricks.
1.High cold crushing strength
2.High refractoriness under the load
3.Good creep resistance
4.High-temperature endurable
5.Good resistance to abrasion and corrosion
6.High mechanical strength
Andalusite Brick Description
Andalusite bricks are made of andalusite as the main raw material, which can save energy by 30-50% compared with refractory soil or light brick furnace lining. Using andalusite refractory bricks can not only reduce fuel consumption and increase stability, but also save 40% The above consumption of general refractory materials. It is enables the production to run for a long time and generate great economic benefits, and is conducive to energy saving and consumption reduction and pollution reduction.
The Application of Andalusite Brick
Andalusite brick are mainly used in the chemical and ceramic industries, and in coke oven doors, and in linings and baffles of hot blast stoves.
Andalusite brick are widely used in composite bricks, vaults and straight sections of hot air vents in ladles, kiln cars, coke ovens, steel industries.
Andalusite brick are widely used in the professional manufacture of key parts such as blast furnaces, hot air towers, and reheating.
blast furnaces.
