The steel sheet contains up to 0.005% of C, 2.0 to 7.0& Si in terms of weight % and the balance iron and unavoidable impurities. An oxide film which mainly contains forsterite is formed on the surface and an insulating coating is formed on the oxide film. The peak intensity of Si obtained by glow discharge spectral analysis (GDS analysis) from the oxide film surface is at least ½ of that of Al, and the depth of the peak position of Si from the oxide film surface us up to {fraction (1/10)} of the depth of that of Al. The sheet satisfies the formulas for a ratio y(%) with which peeling of the oxide film does not take place when subjected to a bending test with a curvature of 20 mm and for core loss characteristic W (W/kg): y(%)≧−122.45t+112.55 W (W/kg)≦2.37t+0.280 wherein t represents a sheet thickness in terms of mm.

摘要： A quench solidification method, wherein a steel cast strip having a mean grain size 50 μm or more is prepared and then the steel cast strip is rolled to produce a non-oriented electrical steel sheet having high magnetic flux density in both L and C directions. However the magnetic flux density reduces when the cold reduction rate exceeds 70%. To avoid this problem the non-oriented electrical steel sheet is manufactured with a ratio of at least 4 of the integrated intensity of the {100} plane for a given sample of steel to the integrated intensity of {100} plane for a “random” sample in which crystal grains have random orientations; and a cold reduction rate of the cold-rolling is between 70% and 85%. The superheating degree of the molten steel can be 70° C. or more.
