    摘要: An object of the invention is to make it possible to produce a copper alloy in which the S content is reduced with no contamination with Al, which has a good casting surface and good internal properties and in which eutectic compounds are refined. The invention relates to a slag for electroslag remelting for copper alloy, including CaF 2 : 20 to 45% by mass, CaO: 10 to 30% by mass, SiO 2 : 10 to 30% by mass, LiF: 10 to 20% by mass, and ZrO 2 : 5 to 15% by mass with other impurities: at most 1% by mass, and satisfying a formula:

            17.0 (LiF content + ZrO 2 content) - 556 ≤ CaF 2 content ≤ 4.1 (LiF content + ZrO 2 content) - 80.9.

    and the invention relates to a method for producing a copper alloy with the slag.
