ROLL STAND, MILL TRAIN AND METHOD FOR ROLLING METAL STRIP

摘要

The invention relates to a rolling stand, a rolling train and a method of rolling a metal strip preprofiled in a stepped manner. In order to ensure that the metal strip is free from corrugations in the longitudinal direction of the metal strip even after a thickness reduction with respect to individual steps, it is proposed according to the invention that the thickness reduction be carried out with respect to specific steps while taking into account the following mathematical interrelationship: hj/hj = hi+i/hi+1 = I = constant, where hj represents the amount of thickness reduction in the region of the ith step and hS represents the size of the resulting thickness of the metal strip 200 after the rolling in the region of the ith step.
