    By default, the strip width in a hot-strip mill is deter-mined by edging and rolling the strip in the roughing mill. The width deviation after the finishing mill arises from the width deviation in front of the finishing mill and from width-spread anomaly occurring inside the finish-ing mill. The behavior of width spread in a finishing mill depends on effects in roll bite and on the creep defor
