Title:
METHOD FOR MANUFACTURING GRAIN-ORIENTED ELECTRICAL STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2023/157938
Kind Code:
A1
Abstract:
Proposed is a manufacturing method for obtaining a grain-oriented electrical steel sheet that achieves an improvement in magnetic flux density in materials using an inhibitor. With respect to a steel slab having a predetermined composition, a predetermined relationship between the temperature at the end of rough rolling by hot rolling and the time from the end of rough rolling to the start of finish rolling is satisfied, and the time taken for the temperature to reach 900 °C from 600 °C is set to be at most 50 seconds.
