Document Type and Number:
WIPO Patent Application WO/2024/062766
Kind Code:
A1
Abstract:
Provided, for metal-strip continuous-annealing lines that include a cooling zone where metal-strip cooling is carried out and a temper mill in which post-cooling metal-strip form rectification is carried out, is a method of predicting metal-strip warping form, in which the form of metal-strip warping on the entry-side is taken into consideration to enable quick prediction of the form of warping on the exit side. This method of predicting metal-strip warping form is for predicting an exit-side warping form, which is the form of warping in metal strip 1 along the downstream side of a temper mill 40 in a metal-strip continuous-annealing line that includes: heating equipment for heating metal strip; cooling equipment 30 for cooling metal strip 1 that has been heated in a heating zone; the temper mill 40 for rectifying the form of the metal strip 1 that has been cooled with the cooling equipment; and an entry-side warping form measuring device 16 for measuring, between the cooling equipment 30 and the temper mill 40, an entry-side warping form, which is the form of warping in the metal strip along the upstream side of the temper mill. The form of warping on the exit side is predicted on the basis of: the form of warping on the entry side; and at least one among parameters of operation of the temper mill 40.
