Method and mill train for improving slipping out of metal rolled strip which rolled strip end runs out at rolling speed

摘要

The invention relates to a method for improving the slipping out of a metal rolled strip (1) whose rolled strip end (1a) runs out at a rolling speed from the receptively last roll stand (2) of a multiple-stand mill train (3). During rolling, the strip tension (s) is set between two successive roll stands (F1, F2, F3...Fn) for stabilizing the strip run. The invention provides that shortly і before the rolled strip end (1a) leaves, the generated differential rolling forces are separately measured for each roll stand (F1, F2, F3...Fn), from which pivot value (16) and pivot direction are derived for forming a correction value for the adjustment of the rolls (10, 11) and the adjustment is corrected.
