Abstract

The present invention relates to grain-oriented electrical steel sheet and provides a method for producing grain-oriented electrical steel sheet in which a silicon steel slab having a high carbon content is subjected to heating and hot rolling, and then hot band annealing and cold rolling are carried out, which is followed by decarburization and nitride annealing, and then secondary recrystallization annealing; wherein the decarburization is effected simultaneously with the hot band annealing.
