Abstract
In an aspect, a method of manufacturing a high purity copper-based alloy comprises providing in a melting furnace a feedstock and melting the feedstock. The method additionally includes bubbling an inert gas into the molten copper-based alloy to form the high purity copper-based alloy. Aspects are also directed to an apparatus and a method of fabricating an apparatus for manufacturing the high purity copper-based alloy.
Claims20
An apparatus for manufacturing a copper-based alloy, the apparatus comprising:
- a melting furnace configured to form a molten copper-based alloy comprising at least 50 weight % copper and to bubble-an inert gas through the molten copper-based alloy using a diffusive lining comprising an aluminum-silicate to contact the molten copper-based alloy;
- and
- a transfer ladle configured to receive the molten copper-based alloy and to transfer the molten copper-based alloy into one or more molds or a shot pit configured to solidify the molten copper-based alloy.
