ABSTRACT:
A pouring apparatus for molten metal includes a stirrer installed in a reservoir. The stirrer is rotated by a rotational drive mechanism installed on the reservoir. Molten solder is placed into the reservoir, high melting point metal particles are charged into the molten solder, stirring is performed with the stirrer to uniformly disperse the metal particles in the molten solder, and then the molten solder and dispersed metal particles are cast into a mold. Casting can be performed quickly after charging the metal particles into the molten solder, so the metal particles do not significantly melt into the molten solder.
