Abstract
In cold rolling, sectional profile must be able to be controlled within the limited region where edge drop grows by rolling. The characteristics of profile control are qualified by the experiments in an experimental mill and a real tandem mill installing a work-roll-shift device with tapered work rolls. Studying stress and strain conditions near width edge in a roll gap introduces some infomations concerning to edge drop formation. And the printing ratio of work roll profile, the ratio between change of work roll profile and change of strip profile is introduced as theoretical equations. By this expression, the tendencies of change of edge drop by the change of rolling conditions and work roll shift coditions are able to be estimated. Further the plasticity curve involving the effect of tension feed back near width edge is expressed, and simulations of control of edge drop are performed by introducing the curve into the roll deformation model. By those studies, it is clarified that the range where the plane stress condition affects is a key factor for formation and control of edge drop.
