Title: Method for preventing tail-end squeezing in continuous rolling of steel sheet
Inventor: TAKAHASHI HIDEMITSU
IPC: B21B37/72
Filed: 1984-02-13
Abstract: PURPOSE:To prevent effectively the tail-end squeezing of a rolling material by adjusting the rolling reduction at each side based on the tension difference between the operating and driving sides while an interstand tension is working and leveling the rolling reductions based on the rate of the difference of rolling load at each side at the time when the tail end of material runs out. CONSTITUTION:After the running condition of rolling material is stabilized after biting the front tip of material by an optional stand Sn in the 2nd and subsequent stands of a tandem mill; the tension difference of material between the driving and operating sides at the outlet side of stand Sn is fixed as a lock-on value, and a draft-leveling control is performed so as to make the deviation between the lock-on value and the tension difference of material at each side during running to be zero. Next, the rate of rolling-load difference between the driving and operating sides at the time just after the tail end runs out of a stand Sn-1, is used as a lock-on value; and the draft-leveling control is performed so as to make the deviation between the lock-on value till the tail end runs out of the stand Sn and the rate of rolling load difference during running, to be zero. In this way, the tail end squeezing is prevented.
