摘要
通过对失效的高温过热器管的宏观检查、化学成分分析、力学性能试验和微观金相分析,认为该管爆管属长期超温导致。
This paper introduces the investigation of the super - heater tube burst, including macro - checking, analysis of chemical composition and mechanical properties and microscopy. The reason of the crack is that the tube had been running at overheat condition for the long-period.
