Last-stage moving blade

The invention discloses a last-stage moving blade, relates to the technical field of steam turbine blades, and aims at solving the problem that last-stage blades for high-rotating-speed industrial steam turbines are insufficient and taking an industrial steam turbine set with the rotating speed and the power being over ten thousand as the target. The invention provides a final-stage moving blade which is independently researched and developed, has excellent variable working condition aerodynamic performance and strength vibration performance and is suitable for an industrial steam turbine with the back pressure being 5-25 KPa, the speed regulation range being 7500-11000 rpm and the steam exhaust flow being 70 t/h. The inclined four-tooth fir tree type blade root and half-section loose lacing wire whole-circle connecting structure is adopted, the blade has the excellent variable working condition aerodynamic performance, the strength is high, the damping characteristic is good, the combination of the blade and
