METHOD FOR PRODUCING GRAIN ORIENTED ELECTRICAL STEEL SHEET

A method for producing a grain oriented electrical steel sheet includes a decarburization annealing process where an oxidation degree PH2O/PH2 is controlled, an annealing separator applying process where a mass ratio of MgO and Al2O3 in an annealing separator is controlled, a final annealing process...
