Document Type and Number:
WIPO Patent Application WO/2023/228466
Kind Code:
A1
Abstract:
A meandering control method for a steel sheet according to the present invention comprises: a measurement step for measuring the amount of out-of-plane deformation of the steel sheet on the upstream side of a steering apparatus for changing the transport direction of the steel sheet; a calculation step for calculating the mean curvature of the steel sheet by using the amount of out-of-plane deformation of the steel sheet as measured in the measurement step; and a control step for calculating an off-center amount of the steel sheet in the steering apparatus by using the mean curvature of the steel sheet as calculated in the calculation step, and controlling the wrapping position of the steel sheet relative to the steering apparatus on the basis of the calculated off-center amount.
