Abstract

Provided is a method of producing a grain-oriented electrical steel sheet that can improve magnetic flux density. In the present disclosure, when a steel material having a predetermined chemical composition is sequentially subjected to hot rolling, cold rolling, decarburization annealing, application of an annealing separator, and final annealing, the storage conditions between the final cold rolling and decarburization annealing of a cold-rolled sheet coil and the temperature fluctuation control conditions set during the heating process of decarburization annealing are controlled.
