Patent number: 6148653Abstract: The present invention aims to provide a rolling system and a rolling method capable of avoiding the occurrence of a pinch fold by effectively preventing the zigzag movement of a rear end portion of a material to be rolled. The rotational speeds (rolling speeds) of work rolls (2) of a rolling mill stand (F.sub.1) from which the rear end of a plate material (6) releases, and a succeeding rolling mill stand (F.sub.2) are controlled to the same value. Moreover, the tension between the rolling mill stand (F.sub.1) and the rolling mill stand (F.sub.2) is controlled to zero. The difference in tension between a work side and a drive side can be made null between the rolling mill stand (F.sub.1) and the rolling mill stand (F.sub.2). Similarly, the difference in tension between the work side and the drive side can be made null between the plurality of rolling mill stands (F.sub.2 to F.sub.n) during release of the rear end of the plate material (6).Type: GrantFiled: August 12, 1999Date of Patent: November 21, 2000Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Akira Sako, Toru Takeguchi, Syuji Maniwa, Masashi Yoshikawa
