摘　　要：通过建立森吉米尔二十辊轧机辊系变形模型,计算分析了第一中间辊轴向移动对板形的影响,得到随着第一中间辊横移量的增加,轧件边部减薄现象有明显改善;轧件边部单位宽度轧制力明显地减小,而轧件中部单位宽度轧制力微小的增加;轧件中部前张应力逐渐减小,边部前张应力逐渐增加。通过该模型的建立和分析,为森吉米尔二十辊轧机实际生产带钢提供了理论参考。The effect of the first intermediate roll traverse on strip shape is calculated and analyzed through establishing the deformation model of the roll system in Sendzimir twenty-roller mill. It is found that the strip edge thinning phenomenon is improved obviously as the first intermediate roll traverse quantity increases, the central unit rolling force has a small increase as the unit width rolling force on the strip edge is obviously reduced, the front tension on the edge of rolling piece increase gradually while the front tension on the middle decreases gradually. Through establishment and analysis of the model, a theoretical reference was provided for practical production of Sendzimir twenty-roller mill.
