Description:Ceramic fiber board is manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber board have been further improved due to the higher density. Ceramic fiber board is a vacuum formed product that resists higher gas velocities than ceramic fiber blanket. It is ideal for furnace, boiler duct and stack lining thanks to its low thermal conductivity and low heat storage, which makes the shorter cycle times and quicker access for maintenance in the industrial furnaces possible.
Feature:
-Resistance to thermal shock and gas erosion .
-Easy cutting and engineering, mechanical flexibility.
-Resists penetration by molten aluminum and other non-ferrous metals.
Application:
Refractory lining for industrial furnaces.
Combustion chamber liner, boilers and heaters Back-up insulation for monolithic refractories.
Transfer of non-ferrous metals.
Expansion joint boards Barrier against flame.
