摘要
以运行了八年的三组过热蒸汽炉管为试验材料 ,通过化学成分分析、常温力学性能试验及金相显微组织的观察与宏观分析 ,对三组过热蒸汽炉管的使用安全性进行了全面的评估 。
Three groups of superheating steam furnace tubes that had operated for eight years were used for the analysis of the chemical composition, mechanical properties and microstructure. The testing results and the macro-analysis of the furnace tubes were combined to make safety evaluation. The conclusions obtained in the study will be used as a reference for relevant engineers.
