Abstract: A method for continuously producing foamed metals is disclosed. The method comprises the steps of (i) adding a previously dissolved molten metal to a viscosity-enhancing furnace and agitating the molten metal so as to uniformly maintain the viscosity of the molten metal; (ii) conveying the molten metal to an electronic agitating type foaming furnace; (iii) injecting gas into the conveyed molten metal while agitating to obtain a foamed molten metal; and (iv) drawing the obtained foamed molten metal using a roller and cooling the drawn foamed metal.
