摘　　要：从理论计算的角度,给出了大变形、小变形矫直方案辊数确定流程图,并以5辊和7辊为例,从矫后残余曲率、达到的最大塑性变形率、矫后钢板厚度方向的残余应力、矫直力、功率等多方面深入分析辊数多少的区别,为板材辊式矫直机辊数选取时提供依据。From the theoretical perspective, the calculation flow charts of roller number are given for the large and small deformation straightening scheme. Take 5 rolls and 7 rolls for example, this paper has analyzed the differences of roller number from five aspects, including the residual curvature, the maximum plastic deforma- tion rate, the residual stress on the direction of plate thickness, straightening force and power, which paves the basis for plate roller number selection.
