Production method of automatic correction control method and differential thickness steel plate of differential thickness steel plate

摘要

PROBLEM TO BE SOLVED: To provide a method of an automatically straightening a steel plate having different thickness, which allows automatic determination and automatic operation of the straightening work of the steel plate having different thickness with a roller leveler by the visual decision of an operator.;SOLUTION: The method of controlling automatic straightening of the steel plate having different thickness is provided with: a step where the flatness, the plate thickness and the traveling distance of the steel plate having the different thickness are calculated on the basis of information from a thickness measuring means and a measuring means of the traveling distance of the steel plate; a step where the boundary of the different thickness is decided from the calculated results; and a step where the rolling reduction for straightening is changed from the decided results.;COPYRIGHT: (C)2010,JPO&INPIT
