ABSTRACT:
Single-oriented electrical steel sheets having a high magnetic induction can be produced by hot rolling a silicon steel raw material containing less than 0.06% of C and less than 4% of Si, subjecting to annealing step and cold rolling step conveniently repeatedly to form a cold rolled steel sheet having a final gauge and subjecting to a decarburization annealing and a final annealing to develop secondary recrystallized grains having (110)[001] orientation, said silicon steel raw material being characterized in containing 0.005-0.200% of Sb and less than 0.10% of at least one of Se and S.
Said final annealing for secondary recrystallization at a temperature of 800.degree.-920.degree.C gives a preferable result.
