PROBLEM TO BE SOLVED: To provide a method for producing a copper-iron alloy, by which intrusion of air bubbles is reduced, and an ingot of high quality can be obtained.SOLUTION: A method for producing a copper-iron alloy includes: a charging step S11 of charging electrolytic copper and the particle pieces of pure iron into a melting furnace; a degassing step S12 of melting the electrolytic copper and degassing a gas in the copper molten metal; a reaction step S13 of melting the pure iron and subjecting the copper and iron to crystallization reaction; and a pouring step S14 of pouring the reacted molten metal subjected to the crystallization reaction into a mold. Thus, the gas in the molten metal can be sufficiently degassed before the crystallization reaction between the Cu and Fe in which the viscosity of the molten metal is made high, to obtain an ingot of high quality in which the intrusion of air bubbles is greatly reduced. |
