Ceramic fiber board use temperature and material selection guide

definition:

The ceramic fiber sample is heated and kept for 24 hours, and the temperature at which the linear shrinkage rate is not more than 2.5% is the classification temperature of the ceramic fiber fiber, also called the "brand temperature", the classification temperature of the widely used ceramic fiber in Western Europe, North America and the present, and Not its use temperature.


The use temperature of ceramic fiber refers to the maximum temperature allowed in use. The use temperature of ceramic fiber is different in different furnace types, different heating processes, different furnace gas components or components of sub-protective gas, different fuels used in the furnace, and the gas flow velocity of the furnace. same.

the difference:

For ceramic furnaces used in batch furnaces, the classification temperature is the highest service temperature and for continuous furnaces, the classification temperature is 100-150 °C lower than the maximum temperature. There is one point to be paid attention to here. When the ceramic fiber is used at the highest temperature, it will shorten the life and give a certain safety factor to the maximum operating temperature in practical applications.
