Document Type and Number:
WIPO Patent Application WO/2019/188976
Kind Code:
A1
Abstract:
Provided is a method for producing a grain-oriented electrical steel sheet with which it is possible to obtain a grain-oriented electrical steel sheet exhibiting excellent magnetic properties. This method for producing a grain-oriented electrical steel sheet involves subjecting a surface of a grain-oriented electrical steel sheet which does not have a forsterite film thereon to a film formation treatment, and performing the film formation treatment while imparting tension to the grain-oriented electrical steel sheet which does not have a forsterite film thereon.
