摘　　要：本文对某电厂1号锅炉高温再热器防震支撑板进行了宏观检查、化学成分分析、力学性能检测、金相组织分析、SEM/EDS分析。试验结果和综合分析表明,支撑板受到了渗碳腐蚀和硫腐蚀作用,随着腐蚀进行支撑板厚度不断减薄。In this paper,macroscopical examination,chemical composition analysis,mechanical property test,metallographic structure analysis,SEM/EDS analysis were carried out on the high temperature reheater support plate of No.1 Boiler in a power plant.The test results and comprehensive analysis showed that the support plate was subjected to carburizing corrosion and sulfur corrosion,and the thickness of the support plate is continuously thinned with corrosion.

关 键 词：支撑板 减薄 渗碳腐蚀 硫腐蚀
