Zusammenfassung:	Method for the production of a single oriented silicon steel sheet having excellent magnetic property which comprises providing a silicon steel slab containing 0.010 SIMILAR 0.10% C, 2.5 SIMILAR 4.5% Si, 0.02 SIMILAR 0.15% Mn, and a total of 0.008 SIMILAR 0.080% of one or two of S and Se, hot rolling the silicon steel slabing to sheet, and subjecting the hot rolled sheet to a two-step annealing procedure wherein the first half-step is at a temperature of 1000 DEG SIMILAR 1200 DEG C and the latter half-step at 750 DEG SIMILAR 980 DEG C, and to at least two cold rolling steps.
