Abstract
Provided is a method for producing a zinc alloy capable of obtaining a Zn—Si alloy having a uniform composition. Metal Zn is melted in a crucible (2) provided in a heating furnace (1) to obtain a Zn molten metal (4). Floating of a metal Si powder (6) added to the Zn molten metal (4) is suppressed by a floating suppressing member (5). Heating is performed while a liquid surface of the Zn molten metal (4) is coated with a carbonaceous material (9), thereby melting the metal Si powder (6). The suppression of the floating of the metal Si powder (6) is released to allow the melted Si to be dispersed in the Zn molten metal (4), thereby obtaining a Zn—Si alloy molten metal (11). A copper casting mold (12) is filled with the Zn—Si alloy molten metal (11), and is rapidly cooled down to obtain a billet.
