一、前言欲充分发挥冷连轧机的高生产率,就须实现稳定的高速轧制。冷轧失稳现象中有这样一种情况:若用一组轧辊连续轧多个钢卷,则轧辊周速与板速相等的中性点位置就会移到轧辊变形区出口端,并最终移出轧辊变形区而引起轧辊颤震。八幡制铁所4号冷轧机是极薄板冷轧机,在该轧机上,为了防止这种中性点变动引起的轧制失稳现象,研究了一种前滑率控制系统,借助能高速响应并变 First, the foreword In order to give full play to the high productivity of tandem cold rolling mill, it is necessary to achieve stable high-speed rolling. Cold rolling instability phenomenon such a situation: If a group of rollers continuous rolling multiple coils, the roller speed and plate speed equal to the neutral point position will be moved to the exit of the deformation zone and eventually move out Roller deformation zone caused roll vibration. Hachimantai Iron Works No. 4 cold rolling mill is a very thin plate cold rolling mill, in the mill, in order to prevent this neutral point of change caused by the rolling instability, the study of a slip rate control system, with high-speed Respond and change
