Abstract
A device and method for producing metal slugs, in which: a movable support has a plurality of cavities separated by partition walls, such that the cavities travel over a path, a feeding means is positioned above a location on said path and is capable of forming a stream of molten metal, flowing under the effect of gravity, such that, during the continuous movement of the movable support, the continuous stream of molten metal from the feeding means is divided or fragmented into slugs formed successively in said cavities, under the effect of said partition walls.
Claims13
A device for producing metal slugs, comprising:
- a movable support having a plurality of cavities separated by partition walls, such that the cavities travel over a path, the movable support comprising a rotating plate, said cavities being formed on an annular zone of the rotating plate, and
- a feeding element positioned above a location of said path and capable of forming a stream of molten metal, flowing under the effect of gravity, such that during the continuous movement of the movable support, the continuous stream of molten metal from the feeding element is divided or fragmented into slugs formed successively in said cavities, under the effect of said partition walls;
- wherein the feeding element comprises a melting pot capable of receiving the metal material and provided with at least one lower extrusion orifice, a heating element configured to heat the metal material contained in the melting pot and a pressure element configured to act on the surface of the metal contained in the melting pot, and
- wherein the rotating plate comprises at least one peripheral annular collar having an upper face capable of receiving the slugs extracted from the cavities.
A method for producing metal slugs comprising:
- forming a continuous stream of molten metal material, through at least one lower extrusion orifice of a melting pot containing the metal material and under the effect of a pressure element acting on the surface of the metal contained in the melting pot;
- and
- letting the stream of molten metal flow, under the effect of gravity, above a path over which cavities of a movable support continuously travel, separated by partition walls, such that the stream of molten metal is divided or segmented in slugs formed successively in said cavities, under the effect of said partition walls;
- and
- extracting the slugs from the cavities in an extraction location situated before the slugs reach the location where the continuous stream of molten metal material is formed, for the slugs to be positioned on at least one peripheral annular collar having an upper face capable of receiving the slugs extracted from the cavities.
