摘要
对国产ＺＧ４Ｃｒ２５Ｎｉ３５ＷＮｂ离心铸管进行了高温持久性能试验和渗碳层厚度检测，并用Ｌａｒｓｏｎ－Ｍｉｌｌｅｒ法对炉管的剩余寿命进行了预测。结果表明，国产高离心铸管的剩余寿命超过了进口的ＫＨＲ３５ＣＷ离心铸管。
The high temperature endurance testing and carbonizedthickness detection of domestic ZG4Cr25Ni35WNb centrifugal casting pipe are carried on. The remainer life of furnace pipe are predicted with Larson-Miller mehtod.The results denote that the remainer lifeof dimesitc centrifugal casting pipe exceded that of imported KHR35-CWcentrifugal casting pipe.
