摘要
在不改变25Cr2Ni4MoV化学成分设计的基础上,采取合适的冶炼、锻造工艺,并通过工艺性试验研究,摸索出适合该材质860 MPa高强度等级转子锻件的热处理工艺参数,成功试制出各项性能指标满足标准要求的转子锻件。
Based on maintaining the chemical composition design of 25Cr2Ni4MoV,by adopting the appropriate smelting and forging processes,and by means of technological test and study,the heat treatment parameters which are suitable for 860 MPa high strength grade rotor forgings of this kind of material have been searched out.Meanwhile,the rotor forgings with various qualified properties have been trial manufactured successfully.
