Application of ceramic fiber as high temperature insulation material

 
Ceramic fiber is a high-efficiency energy-saving thermal insulation material. The material itself has the characteristics of ordinary fibers, but also has the high temperature resistance, corrosion resistance and oxidation resistance that ordinary fibers do not have. It is more important to avoid the brittleness of general refractory materials. To a certain extent, it replaces the traditional heavy refractory bricks and is used as the wall lining material of industrial furnaces. First, the thickness of the kiln has been reduced by 1/2, and the mass has been reduced by 60-80%. The steel used for kiln building has been saved by 30-50%, not only saving the cost of kiln building, It also greatly reduces the load of the steel structure of the kiln, thereby extending the service life of the furnace body;
Second, the use of lightweight, low thermal conductivity, and low heat capacity fiber materials as the furnace wall can reduce the surface temperature of the kiln wall and accelerate the heating rate of the kiln, thereby reducing the energy consumption in the furnace temperature operation control. It has a very significant energy-saving effect on the starting and stopping of the heating furnace.
 
Therefore, the biggest advantage of the industrial kiln built with ceramic fiber as the kiln wall is energy saving.
