Method for producing eutectic copper-iron alloy

A method for producing an eutectic copper-iron alloy including CFA (Cu—Fe Alloy) that is a copper-iron new ceramic in which crystal grain fragments containing iron are dispersed in a copper matrix, the method comprising:

• a charging step of charging a first melting furnace with electrolytic copper, and a second melting furnace with pure iron grain fragments, in which the second melting furnace is separated from the first melting furnace;
• a molten copper deoxidizing step of heating and thus melting the electrolytic copper to 1400° C. in the first melting furnace, thus deoxidizing an oxygen-containing gas in the molten copper;
• a molten iron deoxidizing step of heating and thus melting the pure iron to 1600° C. in the second melting furnace, thus deoxidizing an oxygen-containing gas in the molten iron;
• a molten iron transfer step of further increasing a temperature of the molten iron generated in the second melting furnace to 1650° C., and then transferring the molten iron to a primary reaction furnace which is separated from the first melting furnace and the second melting furnace;
• a molten copper transfer step of increasing a temperature of the molten copper generated in the first melting furnace to 1550° C. after the molten iron transfer step, and then transferring the molten copper to the primary reaction furnace;
• a reaction step of heating the primary reaction furnace to 1600° C. and causing a crystallization reaction between copper contained in the molten copper and iron contained in the molten iron in the primary reaction furnace;
• a molten mixture transfer step of transferring a molten mixture generated in the primary reaction furnace into a mold;
• a cooling step of cooling the molten mixture transferred into the mold;
• and
• a processing step of processing a cast product generated in the mold.
