摘要
本文分析了矩形截面环件轧制尺寸变化规律和阶梯孔环件轧制变形特征。证明了阶梯孔环件轧制中存在轴向体积流动，并导出了体积流动量计算式。基于轴向体积流动规律导出了阶梯孔环件轧制尺寸变化的计算式。通过阶梯孔环件轧制实验，验证了理论尺寸计算式的正确性。
The axial volume flow for rolling ring with stepped hole is demonstrated based on its deformation characteristics and dimension variation law of ring with rectangular cross section, and the voltlme flow amount is calculated. The dimension calculation formulae for rolling ring with stepped hole are derived from the axial volume flow law and verified by rolling expel iment.
