ABSTRACT:
A method for producing high magnetic flux density grain oriented electrical steel sheets or strips having a B.sub.8 characteristic in the rolling direction of not less than 1.9 Wb/m.sup.2 by hot rolling, continuous annealing for precipitation of the AlN, cold rolling into the final thickness, decarburization annealing, and finishing annealing. The cold rolling includes a final rolling at a strong reduction between 81 and 95%.
