耐火纤维炉衬损坏机理

The damage cause for ceramic fibre linings

耐火纤维炉衬经长期高温使用后,易粉化脱落。作者通过对纤维微观组织的观察与分析,找出其损坏原因。因而提出在使用时应以纤维收缩率来衡量其寿命并确定使用温度。

The ceramic fibre linings are easy to effloresce and drop after used for a long time at high temperature. The causes for damage have been found after the observation and analysis of the fibre microstructure. The article advances that the shrinking rate of ceramic fibre should be taken into account when the longevity and working temperature considered.
