A tubular thermal sprayed melt containment component for transient containment of molten metal or alloy wherein the tubular member includes a thermal sprayed inner melt-contacting layer for contacting molten metal or alloy to be processed, a thermal sprayed heat-generating layer deposited on the inner layer, and an optional thermal sprayed outer thermal insulating layer. The thermal sprayed heat-generating layer is inductively heated as a susceptor of an induction field or electrical resistively heated by passing electrical current therethrough. The tubular thermal sprayed melt containment component can comprise an elongated melt pour tube of a gas atomization apparatus where the melt pour tube supplies molten material from a crucible to an underlying melt atomization nozzle.
The combination of a tubular melt containment member for containment of molten material and including an inner thermal sprayed melt-contacting layer, a thermal sprayed heat-generating layer deposited on said inner layer, a thermally sprayed outer thermal insulating layer deposited on said heat-generating layer, and means for causing said heat-generating layer to generate heat.
A tubular melt containment member for containment of molten material including an inner thermal sprayed melt-contacting layer for contacting molten material to be processed, a thermal sprayed heat-generating layer deposited on said inner layer, and a thermally sprayed outer thermal insulating layer deposited on said heat-generating layer.
Gas atomization apparatus comprising a crucible for containing molten material to be atomized, an atomizing nozzle and a melt supply tube between said crucible and said nozzle, said supply tube comprising a thermal sprayed inner melt-contacting layer for contacting molten material to be processed and a thermal sprayed heat-generating layer deposited on said inner layer, and means for heating said heat-generating layer by induction or electrical resistance.
Method containing a molten material, comprising contacting said molten material with a tubular containment member having an inner thermal sprayed melt-contacting layer for contacting said molten material and a thermal sprayed heat-generating layer deposited on the inner layer, and generating heat from said heat-generating layer.
