汽轮机汽缸用ZG22Mo铸钢件高温强度研究

Research on High Temperature Strength of ZG22Mo Casting Steel for Steam Turbine Cylinder

通过对汽轮机汽缸用ZG22Mo铸钢件的4个温度点各进行10组高温拉伸试验,采用正态分布原理对试验数据进行处理得出高温性能的保证值。

10 sets of high temperature tension tests have been carried out on four temperature points of ZG22Mocasting steel used for steam turbine cylinder, and test data have been processed with normal distribution principle towork out guaranteed values of high temperature property.
