| Abstract: | The main shaft upper flange forging for a large hydraulic turbine requires high mechanical properties and is difficult to forge.On the basis of the traditional forging process,combined with the forging method of mandrel drawing and step precision expansion,a large high ring forging with flange at the end has been successfully forged,which effectively reduced the gross-to-net ratio of the part. |
