REGULATING WHEEL FOR WELDING ON STEAM TURBINE'S HIGH-PRESSURE ROTOR AND METHOD OF ITS PRODUCTION |
| 摘要 |
A control wheel intended for welding onto the high-pressure rotor of a steam turbine is manufactured from a ring of individual blades welded together. For this purpose, all of the individual blades are provided with shrouds and root platforms having welding grooves formed therein. After being welded together into a ring, closed on all sides, the control wheel is annealed, machined and finally heat-treated. |
