摘　　要：斜轧穿孔机轧辊开度计算是轧机工具设计和调整参数计算的基础。文中分析了下压轧制条件下二辊斜轧穿孔机的轧辊开度，并讨论了轧辊开度的非对称性对穿孔过程及毛管壁厚均匀性的影响。The computation of the roll opening is the basis of tool design and parameters adjustment of skew rolling piercer.The roll opening of skew rolling piercer with a lower rolling line is analyzed,and the effects of non-symmetric roll opening on the process of piercing and the lateral evenness of the wall thickness of shell pierced are disscused.
