摘　　要：指出用道次压下系数法设计异型轧辊孔型比较繁琐,没有考虑管坯的纵向延伸及材料、工艺、操作等影响因素,所以实际生产达不到道次压下系数法的设计要求。公称尺寸设计异型轧辊孔型,不具体分配整形余量,而是直接将成品管公称尺寸作为设计每道、每段轧辊孔型曲线的依据,因此设计程序简单,工作效率高,实用效果好。It is pointed out that the design method involving pass screwdown factor for shaped roll groove is rather complicated. Due to the fact that with this method, such influencing elements as the longitudinal elongation of the billet, the material, the process and the rolling operation are totally out of consideration, the designed re- quirement as derived from the said pass screwdown factor method can not be met in actual rolling process. On the other hand, the nominal dimension design method for the shaped can groove not only requires much less compli- cated design program, but also brings about higher design effectiveness and better result, because with this method no specific distribution of the deformation allowance needs to be considered, and instead, the finished tube nominal dimensions are directly used as the basis for designing each individual pass and each zone of the roll groove profile.
