How to calibrate the warpage of steel strip in electroplating line

摘要

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method for manufacturing an electroplated steel sheet, wherein in a lateral electroplating line, a roll for applying at least one back up roll to face a warpage caused by a rolled through roll and a back up roll. Forming a smaller diameter and at the same time according to the operating conditions provides a method for arranging the back-up roll relative to the energizing roll in the advancing direction of the steel strip by a predetermined value, the offset amount is 5 to It is more preferable to set it as the range of 35 mm.
