ORIENTED ELECTROMAGNETIC STEEL PLATE AND PRODUCTION METHOD FOR SAME. |
摘要 |
The present invention can obtain an oriented electromagnetic steel plate with magnetic domain refinement by electron beam irradiation and which achieves excellent low-noise characteristics when assembled on an existing transformer, as a result of: the ratio (Wa/Wb) between a film thickness (Wa) of a fosterite coating on a distortion introduction side of a steel plate and a film thickness (Wb) of the fosterite coating on a distortion non-introduction side being 0.5 or greater; the average width of a discontinuous section in a magnetic domain in the steel plate surface on the distortion introduction side being 150-300 µm; and the average width of the discontinuous section in the magnetic domain in the steel plate surface on the distortion non-introduction side being 250-500 µm. |
