摘要

A method of dynamic adjustment of the roll gap in a roll stand of a mill train having multiple stands for rolling a strip, with a strip stock, i.e., a loop, between two roll stands being adjusted or limited by a loop or a strip stock control, with the dynamics in adjustment of the roll gap being limited as a function of state variables of the mill train, in particular state variables of the loop or strip stock control.
