摘要： A method for producing grain-oriented electrical steel sheet having metallic luster and excellent punching property comprises the steps of decarbonization annealing a grain-oriented electrical steel sheet which has been cold rolled to a final thickness, coating the decarbonization-annealed sheet with an annealing separator consisting of magnesium blended with one or more salts of alkali metal or alkaline-earth metal, and finish annealing the coated sheet.
