摘　　要：介绍了张减机轧辊椭圆孔型的基本参数及其相互关系,通过实例对张减机椭圆孔型加工参数的计算过程进行了描述,得出了一种简便的孔型计算方法。该方法通过确定减径率、推算覆盖系数、计算椭圆度系数、计算长短轴数值和校核等5个步骤,可得出圆弧直径和偏移距离,从而实现圆弧加偏距的加工方法。经过实际计算和作图结果对比,验证了这种方法的可行性。In this article, it introduced the basic parameters of stretch-reducing mill oval groove and its mutual relation,described processing parameters calculation procedure by taking an example, and a simple calculation method for the groove was obtained. By five steps, including determining the diameter reducing rate, calculating covering coefficient, ovality coefficient calculation, numerical calculation of long axis and short axis, and check, the circular arc diameter and deviation distance were obtained, so as to realize circular arc offset processing method. Through comparison between actual calculation and drawing result, verify the feasibility of this method was verified.
