High aluminun ceramic fiber felts

Aluminum silicate refractory fiber felts is mainly used in inner lining of all kinds of industrial furnace.

Ceramic fiber felts

  Product Station:

Ceramic fiber felts is a kind of light and pliable refractory fiber for thermal insulation materials. Ceramic fiber felts have all the good property of the ceramic fiber bulk; and also have the good strength and stress, it is a multifunctional products.

 Product characteristic:

High compression strength with long service life

Low thermal capacity, low thermal conductivity

Non friability material, with good toughness

Good flatness and exact size

Easy cutting and install, convenient for construction

Excellent weather-proof performance

Manufacture in continuity, equal fiber scattered, steady function

Good performance of sound absorption and noise reduction

Typical application:

1. Steel industry :Heat insulation for dilatation joint, back lining, heat resisting sheet, casting mould

2. Non-ferrous metal: Tundish and the flow slot cover for pouring copper and copper alloys

3. Ceramic Industry:Hot surface lining body for light kiln car structure and kiln

4. Glass industry:heat insulation for molten pool back lining, burner block

5. Kiln construction:hot surface refractory material (replace ceramic fiber blanket), back lining of heavy quality refractory materials, dilatation joint

6. Light industry:Lining for Industrial and household boiler furnace

7. Petrochemical industry: Heating surface material for lining of high temperature heating furnace
