Application Areas
(More information is available on product data sheets and application sheets)
Hot face veneering for existing Furnaces, Kilns and Heaters where the lining is in a reasonably good condition and does not require immediate replacement. Veneering offers reduction in heat loss, leading to fuel savings. Further, the life of the refractory lining is extended due to protection offered by ceramic fiber. Hot face layers where gas velocities are encountered in furnaces, Heaters and Kilns. Launder linings in aluminum plants. Hot face linings in duct work carrying gases. Hot face linings in laboratory-type and other small furnaces & Kilns. Hot face linings of LTM kiln cars. Combustion chamber linings. Aluminum handling applications. Back up insulation in glass tanks, aluminum furnaces and ceramic Kilns. Expansion Joint packing for refractory brickwork. insulating lagging for Pipes / Exhaust Cable protection against Heat / Fire.
Note : Veneering Modules for 1500oC & 1600oC are available on specific request. The product has a normal shelf life of 6 months if exposed to atmosphere, and is therefore supplied in airtight packing. HIGH STRENGTH BOARD is also available on specific request. Melting point
Glass Fiber > 500oC
SS Wire > 1000oC
