Abstract
A grain oriented silicon steel strip and method are provided for producing the same wherein a chevron pattern of scribe lines mechanically refines the magnetic domain wall spacings. Multiple chevron patterns are formed to extend always transversely across the strip width.
Claims18
A grain oriented silicon steel strip having mechanically refined magnetic domain wall spacings formed by mechanically scribing a face surface of the strip, said mechanical scribing consisting of a multiplicity of closely spaced scribe lines extending generally across the width of the strip intersecting magnetic domain walls extending parallel to the rolling direction, said scribe lines being interrupted by at least one directional change across the width of the strip and defining a chevron pattern with the apexes of multiple patterns oriented in the rolling direction.
