ABSTRACT:
A melt tube assembly comprising a melt delivery tube and a supporting and insulating shield providing mechanical protection to the melt tube tip and a thermal barrier between the flowing melt and the gas atomization nozzle and the gas jets issuing therefrom during confined gas atomization. In a preferred embodiment, the melt tube tip is a separate element, easily replaceable or interchangeable without removing the melt delivery tube from the crucible.
