<p><P>PROBLEM TO BE SOLVED: To provide a molten nonferrous metal feeding device which is a feeding device that can feed a fixed quantity of molten metal, e.g., from a molten metal hand furnace to a die casting machine, from a melting furnace to the molten metal hand furnace or the like, and in which the precision of the feeding quantity of molten metal is improved. <P>SOLUTION: The molten nonferrous metal feeding device includes: a freely elevatable molten metal taking-in cylinder in which the upper part is provided with a plurality of molten metal inflow holes, and at least the part including the molten metal inflow holes is immersed into the molten metal of a molten metal furnace; a piston inserted into the molten metal taking-in cylinder and fitted and attached to the lower edge of a tubular piston axis connected with a molten metal outflow tube in a T-shape at the upper part; and a driving means of elevating the molten metal cylinder. Further, the upper part of the cylinder is provided with a laser ranging apparatus performing irradiation against the upper face part of the piston at the inside of the molten metal taking-in cylinder. Further, the upper part of the tubular piston axis is provided with a laser ranging apparatus performing irradiation to the axial direction at the inside of the tubular piston axis. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
