High flux density grain-oriented electrical steel sheet excellent in high magnetic field core loss property and method of producing the same

摘要: A high flux density grain-oriented electrical steel sheet excellent in magnetic field core loss property containing, percentage by weight, not greater than 0.005% of C, 2.0-7.0% Si, 0.2% Mn, one or both S and Se a total amount 0.005%, the balance being Fe unavoidable impurities, optionally 0.065% Al, N 0.003-0.3% each more Sb, Sn, Cu, Mo, Ge, B, Te, As, Cr Bi, having grain orientation deviating from an ideal {110} average 5°, 180° domain width 0.30 mm, preferably 0.26 mm area ratio domains 0.4 3% 20%.
