| Abstract: | Aiming at the problem of the early diagnosis difficulty for the last stage blades of turbinelow -pressure rotor in coal -fired power plant,puts forward the method of using metal magneticmemory technology to detect turbine low-pressure rotor blades,and applies in the detection of theprimary and secondary grade blades at the bottom of the low-pressure rotor in a power plant ofNingxia. The result shows that metal magnetic memory technology,as a new way of non-destructivetest,has better effect for the early diagnosis of turbine blades. |
