环件轧制过程中存在着运动学、动力学、金属塑性及缺陷等非线性约束。常规工艺制订方法很难同时满足这些非线性约束条件。本文提出了综合可轧区的概念，并对综合可轧区进行求解，最后将各种非线性约束用几条曲线统一起来。据此可方便地确定径、轴向压下量范围。它不仅可以保证轧制过程的顺利进行，还可避免鱼尾等缺陷的产生，对实际生产具有指导作用。 Ring rolling process there is kinematics, dynamics, metal plasticity and defects such as non-linear constraints. Conventional process development methods are difficult to satisfy these non-linear constraints at the same time. In this paper, the concept of integrated rollable zone is proposed, and the comprehensive rollable zone is solved. Finally, the various nonlinear constraints are unified by several curves. Based on this, the diameter and axial reduction range can be easily determined. It can not only ensure the smooth progress of the rolling process, but also to avoid the emergence of fish tail defects, the actual production has a guiding role.
