方向性電磁鋼板およびその製造方法

Document Type and Number:

Japanese Patent JP5884165

Kind Code:

B2

Abstract:

Provided is a grain-oriented electrical steel sheet that allows for manufacture of a transformer that exhibits, when the steel sheet is applied to an iron core thereof, extremely low iron loss and extremely low noise properties, makes highly efficient use of energy, and can be used in various environments. The grain-oriented electrical steel sheet according to the present invention has a strain distribution in regions where closure domains are formed, when observed in a cross section in the rolling direction, with a maximum tensile strain in a sheet thickness direction being 0.45 % or less, and with a maximum tensile strain t (%) and a maximum compressive strain c (%) in the rolling direction satisfying the following Expression (1): t + 0.06 ¤ t + c ¤ 0.35
