  • Patent number: 6423113
    Abstract: Fine powders are made from molten metals and alloys on a continuous basis. A rapidly spinning shallow cup has an atomizing fluid such as water, oil or any other hydrocarbon supplied to the cup to form a thin sheet or layer which is distributed on the inner surface of the cup. Within the cup a stream or spray of molten metal is propelled into this thin sheet of atomizing fluid. The metal interacts with the atomizing fluid film and is fragmented or broken down into many small droplets which are quenched by the atomizing fluid and solidified into fine powder. These powders in the form of a slurry with the atomizing fluid can be continuously removed as the slurry discharges up over the lip of the cup by centrifugal force and the powders can be recovered. In a preferred embodiment a preatomizer is positioned between the incoming stream of molten metal and the spinning cup.
