Ceramic Fiber Board
Description:
ceramic fiber board is a lightweight refractory material processed with alumina-silica fibers for applications at temperatures up to 1430C(2600F)
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 due to its low thermal conductivity and low heat storage allowing shorter cycle times and quicker access for maintenance
Features
Low thermal conductivity,saves fuel
Very low heat storage,faster heat and cool-down reducing cycle times
Ligh weight.replaces heavy back-up insulation.less steel required.
Excellent thermal shock resistance
Resistant to hot gas erosion
Resists most chemical attacks
Easy to cut,handle and install
Low sound transmission
Resists penetration by molten aluminum and other non-ferrous metals
Contains no asbestos
Applications:
Refractory lining for industrial furnaces in walls,roofs,doors,stacks,etc.
Combustion chamber liners,boilers and heaters
Back-up insulation for brick and monolithic refractories
Transfer of molten aluminum and other non-ferrous metals
Expansion joint boards
Barrier against flame or heat
Hot face layer for high velocity or abrasive furnace atmosphere
