Development of Thermal Profile Control and High Accurate Mill Setting Technology in Plate Rolling

摘要

A new shape control technology with the variableroll cooling of a work roll in plate mill has been proposed by authors.In this study, to realize this technology in the actual plate millwith the roll-cooling header divided into roll barrel direction, anintegral 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 shownremarkable improvement in plate crown and shape.
