Alumina silicate thermal resistant ceramic fiber insulation rigid board for high temperature furnace
Aluminum silicate ceramic fiber board is made from refractory fibers and organic and inorganic bond by wet method and vacuum forming processing. It is widely used as furnace lining in all kinds high temperature furnace and kiln, and also used for other high temperature resistance application.
1. Low heat capacity, low thermal conductivity.
2. Excellent heat stability and thermal shock resistance.
3. Accurate dimension and good flatness.
4. Excellent anti-erosion properties.
5. Easy to cut to install, easy construction.
6. Good toughness, high strength, long life.
7. Asbestos free.
1. Lining of various kilns for thermal insulation.
2. Flue & chimney linings in furnace & kilns.
3. Furnace door insulation, hot face lining of kilns.
4. High temperature boiler wall insulation, insulation for kiln car.
5.Petrochemical and metallurgy industries- back linings, wall linings, and linings-thermal insulation.
