Abstract
An improved apparatus is set forth wherein powder is produced by melting metal in a crucible where it is then poured into a tundish which directs the molten metal onto a spinning disc means. A nozzle plate has a central opening through which the metal is directed from the tundish to the disc means. An efficient annular nozzle means directs a cooling fluid around the disc means. The crucible has means for tilting it which keeps the molten metal entering the tundish properly as the metal is poured therefrom.
Claims4
An apparatus for producing metal powder comprising a housing, a disc means mounted for rotation, a nozzle plate means in said housing for directing an annular curtain of cooling fluid therefrom around said disc means, said nozzle plate means including three annular manifolds, a first annular inner manifold, a second annular middle manifold, and a third annular outer manifold, said first annular manifold having an annular nozzle, said second manifold having an annular baffle to properly distribute the flow therein, said third annular manifold having an annular distribution box therein for properly distributing the flow therein.
