ORIENTED ELECTRICAL STEEL SHEET AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to an oriented electrical steel sheet and a method for manufacturing the oriented electrical steel sheet. The method for manufacturing the oriented electrical steel sheet includes final high temperature annealing through decarburization and nitriding annealing after cold rolling by performing or omitting hot-rolled sheet annealing after manufacturing a hot rolled plate by hot rolling a steel slab. A decarburization and nitriding annealing process is performed at 35-55°C of a dew point and applies a glassless additive containing MgO in the final high temperature annealing process.
