Andalusite High Alumina Brick Details
Andalusite high alumina bricks are widely used in the blast furnace hot blast stove, carbon calciner, the join of andalusite, mullite, kyanite, such as raw materials, in the 1500 ℃ high temperature firing, solve the traditional ball, vertebral body, fire wall, tile, wall brick, high porosity, high temperature creep rate low refractoriness under load, low thermal stability and defects, greatly improve the performance of high temperature and volume stability of refractory brick, is an ideal product to extend the service life of hot blast stove, baking furnace used.
Andalusite high alumina brick has high softening temperature under load and excellent stability against thermal shock, which 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. Different types of andalusite are used differently.
Features
1. High refractory temperature, resistant to high temperature without melting or softening.
2. Resistant to high temperature and high pressure, refractory brick does not soften at constant pressure.
3. Small thermal expansion coefficient, low thermal conductivity and good insulation.
4. High temperature volume stability.
5. High pressure and abrasion resistance at room temperature and high temperature.
6. Resistance to rapid cooling and rapid heating, strong resistance to thermal stress caused by frequent temperature changes.
7. Strong resistance to chemical erosion and soft slag erosion.
8.Low levels of iron and other impurities
9.Long service life
Application
Andalusite high alumina brick is mainly used as the lining material of blast furnace, hot air furnace, carbon roaster, torpedo car, iron ladle, glass melting furnace, electric furnace top mixing furnace and other high temperature furnaces with dramatic temperature change.
