摘要： A soft magnetic steel sheet is manufactured by mixing an amount of molten scrap iron, an amount of substantially pure molten iron and an amount of substantially pure molten silicon so as to produce a molten alloy containing Fe as a base material, 1.0 to 7.0 wt % of Si, and 0.1 to 1.0 wt % of Cu, forming a soft magnetic steel sheet by subjecting the molten alloy to a liquid rapid cooling single roller process, and heat treating the soft magnetic steel sheet in an inert atmosphere at 600 to 1,200° C.
