摘要： A method for the recovery of free aluminum metal from its dross is disclosed. The dross is charged into a receptacle having at least one inclined sidewall and at least one passageway extending through the receptacle's bottom. The passageway is sized and configured to permit the passage of free aluminum metal but inhibit the passage of the dross' network of solid particles. Dross having been charged into the receptacle is then mechanically compacted by applying compressive forces on the dross towards the inclined sidewall. Such compression causes the free aluminum in the dross to coalesce and pass through the passageway in the receptacle's bottom. Steps are also taken during the aforesaid charging and compaction steps to prevent or inhibit the dross from cooling. Free aluminum passing through the receptacle's bottom passageway is then collected. Compacted dross remaining in the receptacle can be subjected to conventional reprocessing techniques for recovering remaining aluminum contained therein.

摘要： A power driven press for recovering aluminum from aluminum dross is disclosed. The press has a receptacle for containing dross. The receptacle has at least one inclined sidewall and at least one passageway extending through its bottom. The passageway is sized and configured to permit the passage of free aluminum but inhibit the passage of a network of solid particles contained within the dross. Ram means for mechanically compacting the dross is also provided. The ram means applies a compressive force on the dross towards the inclined sidewall of the receptacle to force coalescence and separate a substantial portion of the free aluminum from the dross and pass it through the passageway provided in the receptacle's bottom. The ram means is provided with a ramming surface which faces the inclined sidewall surface of the receptacle. The ramming surface is inclined at an angle which is slightly less than that of the sidewall surface. As such, these surfaces cooperate during compaction to inhibit upward displacement of the dross around the ram means but enhance downward movement of the free aluminum in the dross towards and through the bottom passageway. A power source for reciprocally driving the ram into and out of the receptacle is also provided, as is means for collecting the free aluminum passing through the bottom passageway.

摘要： A method of removing skim from molten metal comprises providing a body of molten metal and passing a fluxing gas therethrough to carry skim to the surface of the metal. The skim on the surface is treated to substantially reduce the amount of molten metal contained therein and to provide the skim in a substantially powdery form. A portion of the treated skim in finely divided form is removed to a collector.

摘要： An improved system for melting metal scrap in a molten melting media includes a housing generally cylindrical in cross section and having upper and lower portions. Metal scrap is introduced to a body of molten melting media contained in the upper portion of the housing. A supply of molten melting media is added to the upper portion of the housing through a volute located in the lower portion. The molten melting media is supplied or added by action of an impeller located in the lower portion and mounted on a drive shaft extending through the upper portion. Vanes are mounted on the drive shaft to control the flow motion of the body of molten melting media and metal scrap in the upper portion of the housing by creating a vortex in this body for purposes of mixing the melting media and metal scrap. An opening is provided in the upper portion to remove melted scrap and melting media at a rate substantially commensurate with their rate of introduction.

摘要： A continuous salt-based process is provided for melting and reclaiming aluminum from aluminum scrap containing impurities including heating a molten salt in a heat bay, mixing the heated salt with aluminum scrap or skim in a charge bay to form a molten charge mixture, separating aluminum from impurities in the charge bay by coalescing aluminum to form a molten aluminum metal pad, chlorinating a portion of the charge mixture from the charge bay to form a chlorinated salt mixture and metal chlorides, removing metal chlorides from the salt mixture, and feeding the salt mixture back to the heat bay. In one aspect, the chlorinating step of the present invention includes introducing carbon monoxide or, preferably, solid carbon to control oxide concentration. The process further comprises adding fluorides and removing metal chlorides from the salt to maintain a preferred salt composition. The metal chlorides can be removed by withdrawing volatile metal chloride gases and electrolytically reducing metal chlorides in the molten salt. A further aspect of the invention permits direct reduction of oxide impurities in the salt by electrolysis. In another aspect of the invention, the scrap itself is used as a consumable heating electrode (i.e., disappearing as the scrap melts) for heating the molten salt. An additional aspect of the invention provides that the molten salt is pumped past heating electrodes, which reduces hot spots that otherwise would lead to fuming and cause instability in the molten bath composition. Yet another aspect of the invention permits removal of carbon impurities, which can be introduced to the molten salt when melting of the scrap causes pyrolysis of organic material associated with the scrap, for example, the lacquer coating on beverage cans.

摘要： Apparatus for melting relatively large floating units of metal scrap in a molten melting media or medium, the units having oxide films and solid, liquid and gaseous inclusions. After the units are charged into a melting medium, layers of freshly melted metal are presented to the molten media. The apparatus includes a bay for heating the molten media and means for pumping the media from the heating bay to a circular bay for receiving the large units of metal scrap. Located in the circular bay is a rotor means for moving the media therein at a velocity sufficient to sweep away the surface and insulating layers of the floating units in a rapid manner such that new metal is rapidly and continuously exposed to the melting media without the floating units being submerged in the media. A third bay is included for collecting skim material from the molten media leaving the circular bay. Inlet and outlet troughs extend tangentially to and from the circular bay for directing molten media respectively to the charging bay from the pumping means and from the charging bay to the skim collecting bay. A combustion chamber is located adjacent the charging bay for burning organic material vaporized in the charging bay.

摘要： An improved method and apparatus for ingesting and melting metal scrap that otherwise tends to float on the surface of a molten melting media. The method includes the steps of providing a supply of the melting media and directing the media from the supply to an upper portion of a receptacle having an outlet opening in the lower portion thereof. The flow of the melting media entering the receptacle produces a free vortex of the media in the receptacle, as the media flows out the lower opening. The amount of the flow of the melting media to the receptacle and the size of the lower opening are such that a predetermined level of the media is maintained in the receptacle. The symmetry and continuity of the flow pattern of the vortex are disturbed in such a manner that floating metal solids (and any associated skim material) entering the vortex from the upper portion of the receptacle are rapidly ingested into the melting media. Such ingestion is much more effective than the limited ingestion capability of an undisturbed vortex.
