Abstract

See full text

The method for manufacturing a grain-oriented electrical steel sheet is a method for manufacturing a grain-oriented electrical steel sheet including a strain region forming process of irradiating the grain-oriented electrical steel sheet having a base steel sheet (1), an intermediate layer (4) disposed to be in contact with the base steel sheet (1), and an insulation coating (3) disposed to be in contact with the intermediate layer (4) with an electron beam and forming a strain region (D) which extends in a direction intersecting a rolling direction of the base steel sheet (1) on a surface of the base steel sheet (1), wherein, in the strain region forming process, a temperature of a central portion of the strain region (D) in the rolling direction of the base steel sheet (1) and an extension direction of the strain region (D) is heated to 800° C. or higher and 2000° C. or lower.
