1) ring with stepped cross sections
台阶截面环件
1.
By researching both the thickness deformation law of the ring with stepped cross sections rolled from the ring with rectangular cross sections and the shrinking-drawing between active and passive deforming parts of the ring, a new concept of compound shrinking-drawing coefficient is proposed and its calculation formula and scope of numeral value .
以此为基础研究了矩形截面环件轧制成形台阶截面环件的壁厚变化规律和环件主动变形部分对被动变形部分的拉缩作用，进一步提出了综合拉缩系数的概念，并给出了其数值的计算式和取值范围。
3) section of outer step
外台阶截面
5) profile ring rolling
异形截面环件
1.
However,the process of profile ring rolling is influenced by lots of factors which the control of ring forming becomes rather complicated.
环件轧制是当前广泛应用于生产无缝环件的一种特殊塑性成形方法,然而轧制异形截面环件影响因素众多,控制环件成形具有高度的复杂性,采用传统的试凑法很难满足产品研发的需要。
6) Circular section member
圆环截面构件
