摘　　要：介绍了28CrMoNiV钢工业汽轮机转子锻件的生产工艺。通过严格控制化学成分,选择合理的锻造及热处理工艺,有效提高了转子锻件质量。同时,通过适当降低回火温度,成功将部分转子从550MPa强度等级提高至670MPa强度等级,满足了设计和生产的实际要求。The manufacturing process of 28CrMoNiV steeirotor forging for industrial steam turbine has been introduced. The quality of rotor forging has been efficiently improved through strict control of chemical composition and proper selection of forging and heat treatment process. Meanwhile, the strength grade of some rotors has been successfully improved from 550 MPa to 670 MPa by properly reducing the tempering temperature, which satisfies the requirement of the design and the production.
