Zusammenfassung:	PURPOSE:To provide a device to efficiently refine scrap such as aluminum brazing sheet to high purity. CONSTITUTION:In a fractional crystallizing device of aluminum scrap the liquid phase metal of high concentration is efficiently separated from primarily crystallized particles by satisfying the inequality: 0.95A>=S>=0.75A, where S is the sectional area of a pressing part of a pressing stamp 7, and A is the sectional area inside a molten metal holding container 1. The rest of the molten metal is easily discharged outside from a discharging passage 4 by satisfying the inequality: L>=H-(h), where L is the height of the pressing part of the pressing stamp 7, H is the height inside the molten metal holding container 1, and (h) is the height of the primarily crystallized particles which are pressed, and forming the discharging passage 4 to the upper part of the container 1 to dip the pressing stamp 7 in the molten metal.
