Abstract
A melt spinning apparatus for casting a stream of rare earth element alloy against a quench wheel includes a tundish heated by a first induction heater; a flow nozzle of boron nitride material for directing molten metal through the outlet of the tundish for distribution against the quench wheel; the nozzle includes a jet forming orifice with a flow transition entrance configured to receive a moving charge of molten metal from the inlet of the nozzle through a large longitudinal bore in the nozzle so as to reduce erosion of the nozzle orifice and to smooth flow so as to produce a uniform casting stream.
