Ceramic Fiber Board Application
Ceramic fiber board is a kind of refractory material, usually composed of alumina and silicate, and it is also called an aluminum silicate board.
Typical Application
●
Steel industry:
expansion joints, lining insulation, insulation sheets and mold insulation;
●
Non-ferrous metal industry:
backing insulation material, tundish and launder cover, used for pouring copper and copper-containing alloys;
●
Ceramic industry:
lightweight kiln car structure and kiln hot surface lining, kiln temperature zone separation and fire-stopping materials;
●
Glass industry:
The molten pool is insulated by lining and burner block;
●
Kiln construction:
hot surface refractory materials (replacing fiber blankets), heavy refractory linings, expansion joints;
●
Light industry:
lining of combustion chambers of industrial and household boilers;
●
Petrochemical industry:
High-temperature heating furnaces are lined with heat-getting surface materials;
●
Building materials industry:
Thermal insulation of cement rotary kiln and other equipment
Also known as aluminum silicate fiber board, it is processed by wet vacuum forming process. The strength of this type of product is higher than fiber blanket and vacuum forming felt, and it is suitable for high-temperature fields that require rigid strength of the product.
