Title:
METHOD FOR FORMING INSULATION FILM SUPERIOR IN ADHESIVENESS ON SURFACE OF GRAIN-ORIENTED ELECTRICAL STEEL SHEET, AND METHOD FOR MANUFACTURING GRAIN- ORIENTED ELECTRICAL STEEL SHEET
Document Type and Number:
Japanese Patent JP2003034880
Kind Code:
A
Abstract:
To provide a method for forming an insulation film superior in adhesion to the surface of a grain-oriented electrical steel sheet.
The method for forming an insulation film by applying a predetermined coating liquid, on the surface of a grain-oriented electrical steel in which forsterite is inhibited to generate or is removed, is characterized by the surface and the coating liquid, which have such properties that the contact angle of the droplet of the coating liquid against the surface is 0-25 degree, when the droplet is dropped on the surface.
