Title:
GRAIN ORIENTED MAGNETIC STEEL SHEET AND PRODUCTION METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2012057232
Kind Code:
A
Abstract:
To provide a grain oriented magnetic steel sheet which exhibits excellent low core loss characteristic when a transformer is manufactured by laminating the grain oriented magnetic steel sheet having core loss reduced by being given strain by irradiation with electron beam.
The grain oriented magnetic steel sheet is characterized in that the irradiated trace of electron beam has sine-wave shape and relation between an amplitude D and a wavelength L of the sine-wave shape satisfies expression (1): 3π≥L/D≥π.
