Specifications

Ceramic fiber board
1.Temperature:1140~1430C
2.Low thermal conductivity
3.Lightweight; Low heat storage
4.Asbestos free

 

LUYANG ceramic fiber board is a lightweight refractory material processed with alumina-silica fibres for applications at temperatures up to 1430C.

 

 

 

LUYANG 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.

 

 

 

Features:

 

 High rigidity and light weight

 

Low thermal conductivity

 

Resistance to thermal shock and gas erosion

 

Easy cutting and engineering,mechanical flexibility

 

Resists penetration by molten aluminum and other non-ferrous metals

 

 

 

Typical Applications:

 

Refractory lining for industrialfurnaces

 

Combustion chamber liner,boiler and heaters

 

Back-up insulation for omolithic refractories

 

Transfer of non-ferrous metals

 

Expansion joint boards

 

Barrier against flame
