ABSTRACT:
This invention relates generically to an automatic strip width control method in a hot rolling mill. More specifically, the present invention relates to a method for controlling a strip width to a predetermined width in a rolling mill equipped with edging rolls which seeks the deviation of strip width by estimating the temperature of a roll material under the edging rolls and controls the roll gap of the edging mill by means of the deviation of strip width thus estimated in order to control the width of the strip to a predetermined level on the basis of the technical conception that there is a certain relation between the temperature of the roll material and the deviation of strip width.
