摘要： 用影响函数法计算了六辊轧机的辊系变形和辊间压力分布,研究了单锥度中间辊对辊间压力分布和轧件横向厚度分布的影响·结果表明采用单锥度中间辊可改善辊间压力分布状态,明显降低辊间压力峰值,但轧件横向厚差稍有增加,最大值出现在轧件边部·计算了不同锥度时的辊间压力分布与轧件横向厚度分布,通过比较辊间压力峰值与轧件边部厚度,确定了最佳锥度范围为1/100～1/150,使HC轧机的辊间单位压力峰值降低15%～20%,轧件横向厚差仅在边部增加几微米,符合板形要求·

Abstract: Rolls' deformation and roll force distribution between rolls on a six-high mill are calculated by influence function method to study the influence of single-taper crowned intermediate rolls on the roll force distribution between rolls and transverse distribution of strip thickness. The results show that the intermediate rolls can improve the roll force distribution between rolls and decrease considerably the peak value of the roll force while the transverse thickness difference of strip increases slightly and attains its maximum value at strip edge. The roll force distribution and transverse distribution of strip thickness with intermediate rolls tapered differently are calculated, and the optimal range of taper is determined 1/100-1/150 by comparing strip edge thickness to the peak value of roll force. Thus, the peak value of roll force can be decreased by 15%-20%, and the transverse thickness difference of strip increased by just few microns. Due to such an improvement, the strip shape can meet the standard required.
