首批国产AP1000汽轮机高压转子锻件的质量监造与评价

Quality Surveillance and Evaluation of First Lot Localized Turbine HP Rotor Forging for AP1000

针对首批国产AP1000汽轮机高压转子锻件的制造过程,分析转子锻件形成过程的技术重点和30Cr2Ni4Mo V材料的回火脆性、组织遗传的特性,以及从质量监造角度分析了主要工艺环节及其质量,并与进口转子锻件的指标进行了对比,对国产锻件的质量水平给出了结论。

Regarding manufacturing process of first lot localized turbine HP rotor for AP1000,the technical focuses to forging,temper embritlement and structural herdity of 30Cr2Ni4 Mov are analyzed. Main process and its quality are analyzed through surveillance aspects,comparison work on technical values between localized forging and imported forging is done and conclusion of the quality level for localized forging is proposed.
