Ceramic Fibre Board for Heating Furnace (Wholesale Product)
Item |
Ceramic Fiber Board |
Product Description |
Yaohua ceramic fiber board is a vacuum formed products that resists higher gas velocities than ceramic fiber blanket. 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. |
Excellent Features |
High temperature stability Excellent thermal shock resistance Excellent strength, hardness Exceptional machinability for precise dimensional control Low thermal conductivity Low heat storage Resistant to hot gas erosion Resists most chemical attacks Easy to cut, handle and install Low sound transmission Light weight Resists penetration by molten aluminum and other non-ferrous metals Asbestos free |
Typical Applications |
Refractory lining for industrial furnaces for 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 |
