摘要
对某电厂已经运行约1.68×105 h的亚临界机组低温过热器管进行材质性能试验研究,测定了该受热面管的拉伸强度和高温蠕变性能,最后采用基于连续损伤力学方法对其进行老化状态评估,评估结果表明,在规定温度和压力下,可继续运行73 000 h左右.
The experimental study of 12CrlMoV steel for the power plant was carried out by analyzing the tensilestrength, microhardness and high temperature creep performance test. Finally,the aging condition of the heating surface tube was assessed using the finite ele- ment method based on the continuous damage mechanics theory. The result indicates the su- perheater tube still serve about more than 73,000 hours, under the specified temperature and pressure
