Title:
DETERMINATION METHOD FOR TENSION PATTERN AND ROLL-UP METHOD FOR STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2021/235498
Kind Code:
A1
Abstract:
The present invention presents a method that can, regardless of the properties of a steel sheet, prevent the kinking and/or crushing of the steel sheet which has been rolled up in a coil shape. The method is for determining the pattern for tension which is to be applied as a load to the steel sheet in order to roll up the steel sheet in a coil shape, wherein the method is characterized in that the tension pattern is calculated using the apparent modulus of elasticity in the radial direction of the coil.
