确定冷轧带钢轧制力时,必须考虑在变形区中因轧辊弹性压扁而使变形区长度增大这一因素。尤其是,当变形抗力超出50公斤/毫米~2时,在接触变形区中轧辊辊面产生的弹性压扁是不容忽视的,有时它能使接触变形区长度与不考虑压扁时的相比增长一倍以上。往往由于不能准确的决定出接触变形区长度,而得不到比较可靠的轧制力能参数,从而影响正确的进行设备设计和工艺制度的制定。早在三十年代,J.Hichcock[1]就提出了计算考虑轧辊弹性压扁时接触变形区长度和
When determining the rolling force of cold-rolled strip, the factor that the length of the deformation zone must be increased due to the elastic crushing of the roll in the deformation zone must be considered. In particular, when the deformation resistance exceeds 50 kg / mm 2, the elastic crushing of the roll surface in the contact deformation zone can not be neglected, and sometimes it makes the length of the contact deformation zone less than that in the case of not considering crushing More than doubled. Often can not accurately determine the length of the contact deformation zone, and can not get a more reliable parameters of the rolling force, thus affecting the correct design of equipment and process system. As early as the thirties, J.Hichcock [1] proposed to calculate the contact deformation zone length and
