Title:
圧延スタンドのロール摩耗分散方法および圧延システム
Document Type and Number:
Japanese Patent JP6813101
Kind Code:
B2
Abstract:
When an opposite direction shift for obtaining a required equivalent roll crown and a same direction shift for wear dispersion are used in combination, a difference occurs in the roll gap at both edge portions in the width direction of a rolling target material. Therefore, the difference between a work-side screw down position and a drive-side screw down position is changed so that the roll gap difference between both the edge portions in the width direction of the rolling target material is made close to zero. As a result, the distance between the work roll shafts on a work side and a drive side is changed, so that the roll gap difference at both ends in the width direction of the rolling target material approaches zero. Therefore, the wear of the work rolls can be dispersed while maintaining the equivalent roll crown.
