Abstract
Abstract—Shape defects in coils of cold-rolled strip are analyzed. An algorithm for assessing the stability loss of coils is proposed, on the basis of a fundamentally new approach to calculating the stress–strain state in strip winding on the drum of the cold-rolling mill. Methods are recommended for preventing the following defects of coils of cold-rolled thin steel sheet: sagging, folded structure, mutual slip of the layers, and telescopic distortion.
