Factors affecting the service life of refractory castable lining of rotary kiln

refractory castable liningFactors affecting the service life of refractory castable lining of rotary kiln

The production practice proves that the main factors affecting the service life of the refractory castable lining are the quality of the castable itself, the construction quality of the lining, the health condition, the production operation, and the frequent shutdown of the kiln caused by the electromechanical failure of the calcination system.

First, the quality and management of refractory castables

Second, the construction quality of the lining

Third, the operation is unstable
1.Drying procedures
2.Daily operation

Fourth, electrical and mechanical failures cause frequent shutdown of the kiln

In short, in the production process, the main factors affecting the service life of the lining are: (1) the lining temperature fluctuates sharply or the temperature is too high; (2) the long-term impact and wear of the material on the lining.
