HIGH FLUX DENSITY GRAIN-ORIENTED ELECTRICAL STEEL SHEET EXCELLENT IN HIGH MAGNETIC FIELD CORE LOSS PROPERTY AND METHOD OF PRODUCING THE SAME

摘要

The present invention and configured as a percentage by weight, 0.005% or less of C, 2.0 ~ one or both of 7.0% of Si, the Mn, S and Se in a total amount of 0.005% or less than 0.2%, Fe and parts of inevitable impurities in glass , optionally containing as a percentage by weight, Al, N, and 0.003 ~ 0.3% Sb, Sn, Cu, Mo, Ge, B, Te, as, Cr and one or more of Bi, each of not more than 0.005% of less than 0.065% and relates to a magnetic core loss characteristics are superior flux density grain-oriented electrical steel sheet work, said steel plate has a direction deviating from the {110} 001 orientation than to average over 5 °, 0.30mm or less, preferably 0.26mm or less, or 0.26mm or more and has an area ratio of magnetic domains having an average 180 ° magnetic domain width of less than 0.30mm, and more than 3% and less than 20% of 0.4mm width.
