Method for influencing strip profile in the edge region of a rolled strip

摘要

The method concerns control of the contour of edge zones of a rolled strip, which compensates for the deliterious side effect of a roll with one-ended taper on the body zone of the roll gap. The method involves superposition of a conventional CVC (continuously variable crown) roll grind. The method uses special CVC rolls whose crown is determined by an offline calculation which are used as working rolls (1, 2).
