ORIENTED ELECTROMAGNETIC STEEL PLATE AND MANUFACTURING METHOD THEREFOR |
摘要 |
The present invention addresses the problem of providing an oriented electromagnetic steel plate that, when used for a transformer core or the like, produces an extremely low amount of noise and iron loss, exhibits high energy utilization efficiency, and enables the manufacture of a transformer that can be used in a variety of environments. The present invention pertains to a strain distribution in a rolling-direction cross section in a region in which closure domains are formed, said strain distribution being characterized in that the maximum tensile strain in the thickness direction is at most 0.45% and the maximum tensile strain (t) (%) and maximum compressive strain (c) (%) in the rolling direction satisfy relation (1). (1) t + 0.06 <= t + c <= 0.35 |
