摘要

针对电站锅炉部件典型金属故障

如短期过热、长期过热、磨损、穿墙管拉裂、异种钢焊缝裂纹、热疲劳裂纹、奥氏体不锈钢弯头裂纹等进行了分析

并给出了相应防止故障的措施。

Abstract

The typical metallic parts fallures occurred on utility boilers

such as short-time overheat.long-time overheat

abrasion demage

tensile crack of wall entrance tube

cracking in weld joints of non-similar steels

cracking due to thermal fatigue

cracking on bends of austenitic stainless steel

etc.

have been analysed

and measures for preventing from above-mentiond failures being given out.
