摘　　要：大型轴类锻件是大型锻件中的典型代表之一,其锻造工艺有其特殊性,锻造过程控制难度较大,容易导致锻件横向力学性能不合格、超声波探伤不合格及粗晶、混晶现象的发生从而导致废品。尽管很多学者对此进行了大量的研究,并提出了一些工艺方法,但在实际应用中的效果并不是太好,其中一个很大的问题是定性的原则多,缺少具有可执行性的定量标准。本文采用任猛提出的"有效压实工艺准则",使得轴类锻件的工艺编制有了定量标准,能够指导制定详细的、具有很强操作性的锻造工艺,用来指导生产,确保了锻件生产的高质量和稳定性。Large shaft forgings are one of the typical representatives of large forgings, its forging process has its particularity, Forging process control is more difficult. Easily lead to transverse mechanical properties of forgings failed, ultrasonic testing failed and coarse grains, mixed crystal phenomenon occurred in the resulting waste. Although many scholars have done a lot of research, and put forward some of the process, but in the practical application of the effect is not very good, One of the big problems is the principle of qualitative, lack of executable quantitative standards. In this paper, the use of REN MENG proposed “effective compaction process guidelines” that the process of shaft forging process has a quantitative standard. It’s able to guide the development of detailed, highly operational forging process, used to guide the production, to ensure that the forging production of high quality and stability.
