Abstract: Single-oriented electrical steel sheets having a high magnetic induction are produced by combining specifically limited conditions in the composition of raw material, the final cold rolling reduction rate and in the secondary recrystallizing annealing.

Abstract: Electrical steel sheets having a very high magnetic induction are produced by a method in which an electrical steel raw material is hot rolled and annealed and subjected to at least one cold rolling and to a decarburizing annealing and a final annealing to develop the secondary recrystallized grains of (110) [001] orientation characterized in that the raw material contains less than 4.5% of Si, less than 0.06% of C, 0.005-0.100% of Sb and 0.01-0.05% of Al in the electrical steel raw material prior to the hot rolling, annealing at a temperature of 750.degree. - 1,200.degree.C depending upon the Si content before the final cold rolling, final cold rolling at a reduction rate of 40 - 89% and fully developing the secondary recrystallized grains at a temperature range of 800.degree. - 950.degree.C in the final annealing, are carried out in the above described order.

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.
