Title:
COLD-ROLLED STEEL SHEET MANUFACTURING METHOD AND COLD-ROLLED STEEL SHEET MANUFACTURING FACILITY
Document Type and Number:
WIPO Patent Application WO/2022/230229
Kind Code:
A1
Abstract:
The present invention provides a cold-rolled steel sheet manufacturing method using: a full-width heating device that heats a steel sheet over the entire area thereof in the width direction; an edge-section heating device that heats edge sections of the steel sheet in the width direction; and a cold rolling machine that is disposed downstream in the rolling direction with respect to the full-width heating device and the edge-section heating device and that rolls the steel sheet. The method includes a step for heating the steel sheet by using the full-width heating device and the edge-section heating device such that the temperatures of the edge sections of the steel sheet in the width direction become higher than the temperature of a center section of the steel sheet in the width direction at an entry side of the cold rolling machine.
