| 摘 要： | 奥氏体不锈钢锅炉管在供货前应进行固溶处理,否则易造成部分锅炉受热面管的开裂泄漏。选取了3个电厂的奥氏体不锈钢过热器开裂弯管样进行试验分析,探讨固溶处理对该类锅炉管性能的影响。试验结果表明,奥氏体不锈钢高温过热器弯管开裂是因奥氏体不锈钢管未按标准进行固溶处理即供货,运行时在管子加工残余应力、弯管残余应力、热膨胀应力共同作用下造成了沿晶氧化腐蚀所致。对此,提出了相应的防止措施。

| Abstract: | The solid solution heat treatment should be carried out before furnishing austenite stainless steel boiler tubes,otherwise,it is easily to make partial tubes on heating surface of the boiler to be cracked and leaked.Tube samples of cracked bend tubes selected from the austenite stainless steel superheaters of three power plants have been tested and analysed,an approach to the influence of solid soluation heat treatment upon the performance of these boiler tubes being made.Results of test and study show that... |
