ABSTRACT:
Method and apparatus for making a Cu-Cr melt involves melting Cu-bearing alloy component in a melting vessel disposed in ambient air atmosphere, retaining Cr-bearing alloy component in an inverted ceramic crucible held submerged in the melted Cu-bearing alloy component, introducing inert gas into the melted Cu-bearing alloy component, and flowing the melted Cu-bearing alloy component in the melting vessel through openings in the submerged crucible to contact the Cr-bearing alloy component.
