High Temperature Furnace and Heat Insulation Ceramic Fiber Board Aluminum Silicate Board
Ceramic fiber board are furnace refractory and insulation material, take ceramic fiber as the main raw materials, after fiber processing, slag removing, then add some binder, through vacuum forming process and drying process, to be made into high strength fiber board.

Application
1. Steel industry: expansion joints, lining insulation, heat insulation sheets and mold insulation;
2. Non-ferrous metal industry: backing insulation materials, tundish and runner cover for pouring copper and copper-containing alloys;
3. Ceramic industry: the structure of the light kiln car and the hot lining of the kiln, the separation of the temperature zones of the kiln and the fire-blocking materials;
4. Glass industry: the molten pool is lined with heat, and the burner block;
5. Kiln construction: hot surface refractory material (instead of fiber blanket), lining of heavy refractory material, expansion joint;
6. Light industry: the lining of industrial and domestic boiler combustion chambers;
7. Petrochemical industry: high-temperature heating furnace lined with hot surface materials;
8. Building materials industry: insulation of equipment such as cement rotary kiln
