We all know that when using ceramic fiber blankets, we should maintain them regularly so as to extend the service life. In addition to maintaining the extended life, the temperature can also affect the temperature. Here is how the temperature of the ceramic fiber blanket affects the service life:
First of all, it must be used under the temperature conditions allowed, and the development of the crystal is slow.
The properties of the fiber are relatively stable, and the life span can reach 5-10 years in the case of no external force collision in an oxidizing atmosphere.
Secondly, the use temperature of the refractory heat-insulating fiber should be determined according to the type of fuel used in the kiln (gas, oil, coal), the kiln atmosphere, and the composition of the corrosive substance in the kiln atmosphere, and the reducing furnace gas should be used in high purity. As a raw material, the aluminum silicate needle blanket is used as the material of the industrial furnace wall.
The anti-corrosion coating is applied on the surface of the ceramic fiber lining, so as not only to improve the chemical stability of the aluminum silicate fiber lining, but also to improve the wind resistance of the aluminum silicate fiber lining and reduce the heat shrinkage of the fiber lining.
In order to obtain the same thermal insulation effect as the refractory fiber wall lining working under a reducing atmosphere, it is necessary to calculate the thickness of the thickened aluminum silicate needle blanket wall lining according to the composition of the reducing atmosphere.
As long as the service life is increased, our production cost will be reduced. Therefore, the temperature control must be carried out according to the required temperature during use, so that the service life of the ceramic fiber blanket will be prolonged.
