Characteristics:
Calcium silicate insulation boards are used on all kinds of industrial branches to provide high quality insulating backing.
In kiln system, the insulation board is not exposed to the fire. So the requirement to the insulation material is different from
refractory material. Very high use temperature , very high thermal shock resistance and very high mechanical strength are the requirement to refractory material which touch the fire directly. But these items are not important to insulation material. The necessary technical properties for insulation material as following:
Low thermal conductivity.
Low bulk density.
Gas resistance(CO,NH3,H2 and CH4)
Easy cut and installation.
Calcium silicate can meet all above requirement and replace other insulation material, it is becoming dominant on insulation of industrial kiln.


Application:
Cement industry: preheaters and cyclone separators, decomposition kiln, tertiary air duct and cooler.
Nonferrous metals industry: aluminum power calciner and electrolysis groove.
Petrochemical industry: Splitting furnace, catalytic cracking furnace, petroleum pipeline , underground heat-flooding.
Metallurgical industry(steel plant): hot-rolling heat furnace, cool-rolling mill set, RH vacuum degassing furnace, smelters, hot deformation and heat treatment plants.
Power plants :preheat stove, pipe.
Glass industry: melting furnace and recuperater , annealing furnace and cooling channels.
Ceramic industry : chamber and tunnel furnace.
