Abstract: PURPOSE:To enable tapping without using sand and to prevent intrusion of foreign matter into a molten metal in a storage vessel having a bottom running nozzle by heating the metal in an upper nozzle by Joule heat when said metal solidifies. CONSTITUTION:A molten metal is charged into a ladle 1 and is subjected to the treatment necessary for charging to a prescribed mold, etc. When the molten metal in an opening 2 solidifies during this time, electric power is supplied between an electrode 9 and an open/shut plate 4 from an AC power source 12. Then the electric current flows through the molten metal A, the solidified metal in the opening 2 and the plate 4. The metal in the opening 2 of an upper nozzle 3 is melted by the Joule heat which said electric current generates, thus enabling tapping. The plate 4 is thereupon moved to bring the hole 5 opposite to the opening 2 thereby tapping the molten metal.
