Abstract (en)
[origin: EP0799661A2] A method and an apparatus for supplying molten metal to a casting machine wherein the amount of molten metal supplied can be controlled precisely and defective castings caused by slag in the molten metal can be prevented. Material supply means (2) supplies a ladle (1) with a suitable amount of a casting material for one shot of casting in a solid state. After the solid casting material (14) is melted into molten metal, the molten metal is supplied from the ladle to the casting machine. By controlling the amount of molten metal supplied by means of the casting material in the solid state, the precision of quantity control of molten metal can be enhanced. In addition, because the molten metal is supplied from the ladle to the casting machine soon after the casting material is melted, the time for molten metal to be exposed to the air can be shortened, and slag generation due to molten metal oxidization can be suppressed.
