Title:
ROLLING EQUIPMENT AND ROLLING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/152868
Kind Code:
A1
Abstract:
Rolling equipment includes a strip wedge controller that obtains the distribution in the strip width direction of a strip load applied to a rolled material 5 from a work side load PW and a drive side load PD, that calculates the strip wedge after the rolling based on the distribution in the strip width direction of the strip load obtained and the position in the strip width direction of the rolled material 5 set by a rolled material position setting device, that computes a working roll gap difference between the work side and the drive side of a vertical pair of an upper working roll 21 and a lower working roll 31 for making the strip wedge after the rolling calculated a predetermined value, and that controls the drive side hydraulic cylinder 11D and the work side hydraulic cylinder 11W such that the working roll gap difference computed is attained.
