Alumina - Silicate Ceramic Fiber Blanket
1.Brief Introduction
Ceramic Fiber Paper is manufactured from high-grade ceramic fiber with low slag ball content, and formed into excellent flexible sheet through unique beating, deslagging, slurry-compounding, long net forming, vacuum water removal, drying, cutting and rolling processes.
2.Advantage
1)Lightweight , Easy to wrap, shape or cut
2)Low thermal conductivity; Low heat storage
3)None asbest and anticorrosion
4)Good uniformity and smooth appearance
3.Application
1)Die cut gaskets between castings in coke oven doors, blast furnace hot air piping, aluminium heat treating furnace, tuyeres and heat treat furnaces.
2)Backup for brick and monolithic refractories in blast furnace stoves, piping, tundish, ladle, hot metal cars, trough etc.
3)Mould wrapping for controlled cooling
4)Shield for welding & brazing operation
5)Rotary klin back-up insulation
6)Fabricated into tapout cones for Aluminium industry.
7)Strips in bottom of ingot mould for sealing
8)Expansion joint packing
