Method and apparatus for introducing additives into a casting mold

摘要

An apparatus for introducing additives into molten metal being poured through a flow path and into a casting cavity of a casting mold includes a wire feed mechanism for feeding a wire of additive material into the molten metal in the flow path for erodibly mixing with the molten metal prior to its entry into the casting cavity. A device is provided for moving the wire feed mechanism relative to the casting mold between a feed position in which the end of the wire of additive material is disposed in the flow path and a second position in which the end of the wire is removed therefrom.
