The service life of the ceramic fiber module has a great relationship with the working environment and working atmosphere of the kiln--the environment is relatively stable, and the service life is generally 3-5 years; the environment is unstable, and the service life is only one or two years possible. Influencing factors generally include: high airflow scouring, frequent ultra-high temperature use, etc.; in addition, it has a certain relationship with the quality of the ceramic fiber module. So how to extend the service life of ceramic fiber modules?
1. The design of the thermal insulation scheme of the ceramic fiber module should be standardized, and the selected refractory material should be used at the correct temperature, and there will be no collision between the machine and the workpiece.
2. According to the use environment, temperature, atmosphere, wind speed, select suitable grade products, including classification temperature, density, surface treatment, size and so on. Reasonable selection of materials is the basis to ensure the service life of ceramic fiber modules.
3. The installation process and construction quality of ceramic fiber modules are important factors to ensure the service life of refractory fiber linings. Refractory fibers such as ceramic fiber modules are generally left pre-compressed during installation to supplement the linear shrinkage of the fibers when heated. Strictly follow the drawings during installation to ensure the firmness and tightness of the furnace lining.
