After removing the gas and water vapor, cooling water is applied to the anode surface to cool the anode surface at a time when the anode in the mold is peeled from the mold to a temperature of 650 ° C. to 750 ° C. to solidify the anode surface. A method for preventing swelling of the characteristic anode surface.
