4220 Refractory Ceramic Fiber Board Suppliers
Refractory Ceramic Fiber Board Description:
1. Ceramic fiber board is a lightweight refractory material
processed with alumina-silica fibres for applications at
temperatures up to 1600C.
2. Ceramic fiber board is a vacuum formed product that resists
higher gas velocities than ceramic fiber blanket.
3. It is ideal for furnace,boiler duct and stacking lining dut to its low thermal conductivity and low heat storage allowing shorter cycle times and quicker access for maintenance.
Refractory Ceramic Fiber Board Applications:
1. Refractory lining for industrial furnace.
2. Combustion chamber liner, boilers and heater.
3. Back-up insulation for monolithic refractories.
4. Transfer of non-ferrous metals .
5. Expansion joiot boards.
6. Barrier against flame.
Refractory Ceramic Fiber Board Advantages:
1.Low heat storage.2.Low thermal conductivity.
Refractory Ceramic Fiber Board Specification(mm):
1.600*400*20-50;900*600*20-50,other made according to customers's requirement.
