Abstract:
A method of rolling strip in a rolling train having a plurality of roll stands arranged one behind the other in a rolling direction, the method comprisingrolling the strip by introducing the strip into each of the roll stands with a desired entry thickness and providing each of the roll stands with a desired thickness value with which the strip is to exit from the respective roll stand,changing during rolling of a transition portion of the strip the desired thickness value of a selected roll stand from an initial desired value to a final desired value,changing in any of the roll stands following the selected roll stand during rolling of the transition portion of the strip also the desired thickness values of the roll stands following the selected roll stand from initial desired values to final desired values, andcarrying out the changes of the desired thickness values in the roll stands following the selected roll stand in such a way that for each of the roll stands following the selected roll stand a quotient of a temporary desired thickness value and an instantaneous desired inlet thickness is a constant.
