PROBLEM TO BE SOLVED: To provide an apparatus and method for feeding molten metal or alloy into a mold or other container from a furnace in which the metal or alloy is melted. SOLUTION: The apparatus is intended for feeding molten or semi-molten metal or alloy (hereinafter called "molten metal") from the furnace into the mold or other container. The apparatus includes (1) a U pipe of which one end is connected to a molten metal driving means which drives the molten metal under a pressure of 0.2 MPa or lower and which is immersed in the molten metal in the furnace, and (2) an opening for the inflow of the molten metal in the furnace and a member for opening or closing the opening, which are mounted at the lowermost part of the U pipe. The molten metal driving means is (a) a plunger or (b) a pressurized gas supply unit. The opening is mounted (a) directly onto the U pipe or (b) onto a bypass line set on the U pipe. The invented method for feeding the molten metal uses the apparatus. COPYRIGHT: (C)2011,JPO&INPIT
