摘要
论述了对宝钢生产的T92高压锅炉管所做的成分、室温拉伸、高温拉伸、冲击性能、持久强度、金相检验等试验结果,并对挂炉1年后的T92管进行对比检验分析,讨论宝钢T92钢的组织、性能稳定性。试验表明,宝钢T92高压锅炉管各项技术指标和性能均符合GB 5310—2008及ASMESA213标准要求,挂炉1年后的T92管在650、625℃持久强度分别为78.8、98.7 MPa,高于GB 5310、EN10216对T92钢持久强度要求,适用于超(超)临界机组电站锅炉高温受热面管。
The paper expounded the test results of T92 high pressure boiler tube manufactured by Baosteel,including its chemical composition,tension property at room temperature and high temperature,impact property,creep-rupture strength,metallurgical observation,etc.A comparison between this tube after one year service and the original one was made by Baosteel,in order to discuss and evaluate its microstructure and property stabilities.The results indicated that each index and property of T92 high pressure boiler tube manufactured by Baosteel accorded with the requirement of GB 5310—2008 and ASME SA213.Its persistent strength was 78.8 MPa and 98.7 MPa at 650℃ and 625℃ after one year service,higher than the requirement by GB 5310 and EN10216.This tube was applicable to be used as high pressure boiler tube in USC units.
