ABSTRACT:
Disclosed is a method and an apparatus for producing rapidly-solidified flake particles, which combines centrifugal atomization with metal substrate cooling. A stream of molten metal is disintegrated centrifugally into droplets by a rotating disk. Then the molten droplets are solidified as flake particles as soon as impinging upon the annular planar surface of a cooled rotating concave disk. The solidified flake particles are subsequently departed from the annular planar surface by the centrifugal force and collected in a chamber.
