Title:
WARPED METAL BELT SHAPE ESTIMATION METHOD, METAL BELT ACCEPTANCE DETERMINATION METHOD, METAL BELT MANUFACTURING METHOD, AND WARPED METAL BELT SHAPE ESTIMATION FACILITY
Document Type and Number:
WIPO Patent Application WO/2024/062767
Kind Code:
A1
Abstract:
Provided are a warped metal belt shape estimation method, a metal belt acceptance determination method, and a warped metal belt shape estimation device which can estimate a warped shape in a plate width direction in a state where the tension is unloaded, from the warped shape in the plate width direction in a state where the tension in a longitudinal direction is loaded onto the warped shape in the plate width direction generated by rapid cooling of the metal belt. This warped metal belt shape estimation method estimates the warped shape in the plate width direction of the metal belt in an un-tensioned state where the tension is unloaded, from the shape in the plate width direction of the metal belt in a tensioned state where the tension in the longitudinal direction is loaded, wherein the method comprises: a plate width direction shape measurement step for measuring a plate width direction shape distribution of the metal belt in the tensioned state; an approximate curve calculation step for calculating the plate width direction shape distribution, which is measured in the plate width direction shape measurement step, as an approximate curve approximated by a quadratic curve or a circular arc; and a warped shape estimation step for using the plate width direction shape distribution and the approximate curve to estimate the warped shape in the plate width direction of the metal belt in the unloaded state.
