径向辗环过程尺寸控制的新方法

A new method to control ring-rolling deformation

分析了辗环过程及其变形，建立了径向环件和单阶梯孔件辗环变形过程的数学模型，提出了辗环尺寸控制的新方法，生产应用证明该方法是可行的。

Abstract In the paper, the course and deformation of ring rolling is analysed and the mathematical model of course of ring rolling is established. It is proved that the new method of controlling ring rolling deformation is feasible.
