Abstract (en)
[origin: EP0717119A2] When a copper alloy containing a metal more reactive with oxygen than copper is melted and cast, a feedstock is vacuum melted with an induction melting furnace (4) within an airtight container (5) which has been vacuum evacuated, and thereafter positive pressure is applied (via pipe 26) to the airtight container (5), and the molten metal is discharged from the furnace through a pouring siphon (32) for continuously casting in a mold (51). Said positive pressure is exerted using an inert gas. <IMAGE>
