Title:
板圧延方法および板圧延機
Document Type and Number:
Japanese Patent JP3701981
Kind Code:
B2
Abstract:
The invention provides a strip rolling method applied to a multi-roll strip rolling mill of not less than four rolls including at least a top and a bottom backup roll (24,36) and a top and a bottom work roll (28,32), comprising the steps of:
measuring thrust counterforces in the axial direction of the rolls acting on all the rolls except for the backup rolls in one of the top and the bottom roll assembly or preferably in both the top and the bottom roll assembly;
measuring roll forces of the backup roll acting in the vertical direction on the backup roll chocks of the backup roll in the top and the bottom backup roll on the side of measuring the thrust counterforces;
calculating a target increments of roll positioning devices of the strip rolling mill according to the measured values of the thrust counterforces and the roll forces of the backup roll; and
controlling roll positions according to the target increments of roll positioning devices of the strip rolling mill.
