摘　　要：对屏式过热器管进行了宏观检查、金相显微组织观察和分析以及拉伸性能测试。结果表明,该屏式过热器管失效的主要原因是长时超温与短时超温共同作用的结果。The macro-examination of superheater tube,metallographic observation and microstructure analysis were carried out,and the mechanical properties were tested.The results show that： the main reasons for the platen superheater tube failure are the inter-action results of long-time over temperature and short-time over temperature.

关 键 词：长时超温 短时超温 过热器管 金相组织
