Alumina-Silica Refractory Ceramic Fibre
topic
Alumino-silicate ceramic fibres with 45 to 60 percent alumina and 40 to 55 percent silica are produced by melt spinning or blowing of aluminosilicate melt into discontinuous fibres of 2 to 4 micrometre diameter, providing continuous service temperature to 1260 degrees Celsius as blankets, modules, and paper products for industrial furnace lining in petrochemical, ceramic, glass, and metal heat treatment applications.
Role
Provides the dominant refractory insulation product for industrial process furnace lining applications where operating temperatures between 900 and 1260 degrees Celsius require better thermal performance than mineral wool but do not justify the higher cost of pure alumina or mullite fibres, reducing furnace heat-up time and energy consumption through lower thermal mass lining systems.
