Process and equipment for producing copper alloy material

Abstract

A process for producing a copper alloy material from a copper alloy of a precipitation reinforced type, which contains a process to perform individually a dissolution of a pure copper and a dissolution of an additional element or a mother alloy containing the same, comprises the steps of: melting an element and/or a mother alloy at a same time, that is selected from a Ni, a Co, an Si, a Ni—Cu mother alloy, a Co—Cu mother alloy, an Si—Cu mother alloy, a Ni—Si—Cu mother alloy, and a Co—Si—Cu mother alloy with combining therebetween, and melting thereof with an assistance of a generation of a heat of mixing, in a case of forming a high density melt containing at least either one of the Ni or the Co, and the Si, as high density thereof; forming the high density melt as a content of the Ni to be 80 mass % at maximum; and forming an alloy molten metal having a predetermined component and concentration, by adding the melt into a pure copper molten metal to be supplied from another melting furnace.
