Patent ID: 10094001

Abstract:
Method for producing eutectic copper-iron alloy in which crystal grain fragments containing iron are dispersed in a copper matrix, includes: a charging step charging a first melting furnace (MF) and second MF respectively with electrolytic-copper and pure iron grain fragments; molten copper (MC) deoxidizing step heating electrolytic-copper to at least melting-point in the first MF, melting and deoxidizing the electrolytic-copper; molten iron (MI) deoxidizing step heating pure iron to at least melting-point in the second MF, melting and deoxidizing pure iron; MI transfer step increasing the MI temperature generated in the second MF; transferring the MI to a primary reaction furnace; MC transfer step increasing the MC temperature in the first MF to at least the iron melting-point; transferring the MC to the primary reaction furnace; and a reaction step causing a crystallization reaction between copper in the MC and iron in the MI in the primary reaction furnace.
