• LUYANGWOOL® Insulating board for refractory lining is a lightweight refractory material processed with alumina-silica fibres for applications at temperatures up to 1260C.the 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.

           Application

• Refractory lining for industrial furnace in wall, roofs, stacks and doors,etc.
• Combustion chamber liners,boilers and heaters.
• Back-up insulation for brick,and monolithic refractories.
• Transfer of molten aluminium,and other non-ferrous metals.
• Expansion joint boards
• Barrier against flame or heat
• Hot face layer for high velocity or abrasive furnace atmosphere.
