Title:
SHEET WIDTH CONTROL DEVICE FOR REVERSING ROLLING MILL
Document Type and Number:
WIPO Patent Application WO/2024/034020
Kind Code:
A1
Abstract:
This sheet width control device is applicable to a reversing rolling mill that comprises: an edger that has a pair of edger rolls that perform edge rolling on a material being rolled; and a horizontal rolling mill that is disposed downstream of the edger and has a pair of horizontal rolls that perform horizontal rolling on the material being rolled. The sheet width control device comprises a reduction control device, a reduction position detector, a tracking device, and a sheet width actual value calculation device. The reduction control device is configured to cause the edger to operate such that the pair of edger rolls make contact with the material being rolled during reverse pass rolling. The reduction position detector is configured to detect the reduction position of the edger when the pair of edger rolls are in contact with the material being rolled during reverse pass rolling. The tracking device is configured to track the position in the longitudinal direction of the material being rolled during reverse pass rolling. The sheet width actual value calculation device is configured to calculate a sheet width actual value for the material being rolled at a plurality of positions in the longitudinal direction on the basis of the output of the reduction position detector and the output of the tracking device.
