Abstract
Metal filament forming apparatus including a casting crucible having a tapping orifice and a casting nozzle for ejecting molten metal from the crucible are described. The casting nozzle is characterized by having an externally replaceable orifice member. The casting nozzle comprises three parts: (1) a nozzle body providing a conduit for the molten metal in association with the tapping orifice; (2) a replaceable orifice member positioned at the lower end of the nozzle body; and (3) retaining means for holding the replaceable orifice member in sealing engagement with the nozzle body. The crucible is preferably provided with a stopper rod to permit discontinuation of metal flow through the nozzle, while holding molten metal in the crucible.
