摘　　要：对我国首台600MW超临界汽轮机低压转子末级叶片装配过程进行详细论述。在装配过程中,保证叶片围带的间隙、凸台拉筋间隙要求,使叶片的辐射线位置正确。保证机组通流间隙和运行的可靠性。This article detailed decript the assembly process of last stage blades for LP rotor of 600MW super-criticle steam turbine. During assembling, keep the clearance of shrouds and the clearance of lugging for blading and make the blades corrective positioning in radiation, which ensure the clearance of flow passage and the reliability of operation for unit.
