Development of thermal profile control and high accurate mill setting technology in plate rolling

A new shape control technology with the variable roll cooling of a work roll in plate mill has been proposed by authors. In this study, to realize this technology in the actual plate mill with the roll-cooling header divided into roll barrel direction, an integral approach has employed combing the following aspects: development of accurate plate crown and gauge meter models, construction of these models to the pass schedule and mill setting method, installing the fuzzy control of roll cooling on rolling campaign. Results of actual operation of this technology have shown remarkable improvement in plate crown and shape.
