Research on Manufacturing Technologies of 600MW Steam Turbine Governing-stage Moving Blades

WU Han-fu

Abstract

By analyzing the structural characteristics of 600MW steam turbine governing-stage moving blades deeply and in detail,overall scheme and concrete operations or steps for manufacturing the moving blades of governing stages are made.To manufacture them,an entire moving blade of governing stage is divided into three sections,namely,blade root,blade body and blade tip.Based on the analyzation and comparison of manufacturing technologies,operations and cutting steps of each moving blade section,and machine tool,cutting tool,mesure.The concrete machining plan whicn is feasible and not let advanced is presented.
