PCT No. PCT/FR90/00033 Sec. 371 Date Sep. 10, 1991 Sec. 102(e) Date Sep. 10, 1991 PCT Filed Jan. 16, 1990 PCT Pub. No. WO90/08002 PCT Pub. Date Jul. 26, 1990.Device and method for feeding molten metal for the pressure casting of metal products. The device for feeding molten metal to a mould 1 of a continuous pressure-casting installation comprises a vessel 2 equipped with a cover 7 carrying a spout 3, the said vessel resting on a frame 4 and comprising a framework 9 for supporting a ladle 10 of molten metal, means for weighing the said ladle and means 20 for raising the said framework. The casting method implementing this device is characterized in that, during the cast, when the quantity of metal in the ladle 10 is greater than a specific quantity, the ladle is held in a low position (position according to reference 32) and, when the quantity of metal becomes less than the said specific quantity, the ladle is raised (position 32') so as to hold the lower end 31 of the spout below the level of the metal contained in the ladle. |
