Title:
ORIENTED ELECTROMAGNETIC STEEL SHEET AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/051535
Kind Code:
A1
Abstract:
An oriented electromagnetic steel sheet with a coating on the surface, wherein the coating satisfies composite elastic modulus: 60-95 GPa; film thickness: at least 1.0 µm; and tension applied on said oriented electromagnetic steel sheet: at least 6.0 MPa. The magnitude of core loss deterioration after roll reduction as ∆W17/50 when the oriented electromagnetic steel sheet is subjected to roll reduction at linear pressure: 68.6 N/cm is 0.010 W/kg or less.
