Abstract

An alloy flake production apparatus () includes a crystallinity control device () for controlling an alloy crystal structure of fed alloy flakes to a desired state, a cooling device () for cooling the alloy flakes discharged from the crystallinity control device (), and a chamber for keeping these devices under reduced pressure or under an inert gas atmosphere. The crystallinity control device () has a rotary heating drum () in a cylindrical shape for heating the fed alloy flakes, and a switching device () for switching between storage and discharge of the alloy flakes fed to an inner wall side of the heating drum (), so that long-time heat treatment is uniformly applied to the alloy flakes immediately after being made by ingot crushing. The heating drum () preferably has a scooping blade plate () for scooping up alloy flakes fed to the inner wall side with its rotation.
