Title:
熱間圧延機におけるストリップ形状制御方法及び装置
Document Type and Number:
Japanese Patent JP4918500
Kind Code:
B2
Abstract:
A hot rolling mill and method for operating the hot rolling mill where the shape of the strip is controlled by localized cooling devices positioned at intervals along work rolls in at least three lateral zones, a central and two edge zones, and capable of separately cooling each zone to control the shape of the work rolls in that zone and inhibit the formation of shape defects occurring in the strip being rolled. Five zones may be provided across the work surface of the work rolls so that two intermediate zones can control for quarter buckles. The hot rolling mill has particular application in continuously casting thin strip. The method can be made automatic by sensing downstream of the hot mill the shape of the strip in each zone.
