Document Type and Number:
WIPO Patent Application WO/2024/042936
Kind Code:
A1
Abstract:
This cold-rolling method includes a calculation step for calculating the levelling amount of a rolling machine using the out-of-plane deformation amount of a steel sheet measured on the upstream side of the rolling machine, a control step for controlling the levelling of the rolling machine on the basis of the levelling amount calculated in the calculation step, and a cold rolling step for cold-rolling the steel sheet using the rolling machine controlled in the control step.
