Title:
METHOD FOR PRODUCING STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2014/087516
Kind Code:
A1
Abstract:
This method for producing a steel sheet comprises: a hot rolling step for obtaining a hot-rolled steel sheet by subjecting a steel material to hot rolling with a finishing roller; and a cooling step for cooling the hot-rolled steel sheet. The hot rolling step comprises: a target steepness setting step for setting a target steepness of the edge-waved shape of the hot-rolled steel sheet on the basis of first correlation data which indicates the correlation between the steepness of the edge-waved shape of the hot-rolled steel sheet and the temperature standard deviation Y; and a shape control step for controlling an operation parameter of the finishing roller such that the steepness of the edge-waved shape matches the target steepness.
