摘要： A metal melting closed furnace which includes a main chamber, a circulation well connected to the main chamber by a communications passageway and a vortex well having a exit outlet for molten metal into the main chamber. A cover is emplaced over the vortex well. An inert gas bubble activated molten metal pump is provided in which there is an entry port in the circulation well and exit port into the vortex well. The exit port is positioned to lie at least partially or entirely above the maximum level of molten metal in the vortex well. This exit port will typically be at or near the top of the vortex well. In order to reduce oxidation, inert gas bubbles are captured from this molten metal pump and creating an inert gas atmosphere or blanket above the molten metal vortex.

摘要： An inert gas bubble-actuated molten metal pump is located between one section of a metal-melting furnace and a second section to pump molten metal from the one section, wherein the molten metal is at a higher temperature, into the second section, wherein the molten metal is at a lower temperature, and its effluent is directed into contact with metal chips being charged into the second section, thereby assisting in the more rapid melting of the chips into the molten metal mass in the second section. The inert gas employed to actuate the molten metal pump is captured beneath a heat-resistant and flame-resistant cover located above the exit port of the pump and over a substantial portion of the molten metal mass in the second section, thereby providing a non-oxidizing atmosphere at the surface of the molten metal mass or pool beneath said cover. In this manner the inert gas is employed not only to actuate the inert gas bubble-actuated molten metal pump, but also to assist in the rapid melting of metal chips being charged, as well as to provide a non-oxidizing atmosphere at the surface of the molten metal.

摘要： In a device for separating a liquid, as a cutting oil, from a mixture of metal chips and larger pieces of metal, such as bar ends and scrap, there is provided structure for preliminarily separating larger pieces of metal from the entire mass prior to the separation of the oil from the chips. A centrifuge is provided having a drum with an intermediate perforated segment to permit the escape of oil therefrom while the chips move to the upper edge of the drum and thence outwardly to a receiving structure. A chute is provided for feeding the mixture to be separated into the central portion of the drum and a strong stream of air is caused to flow therethrough into the centrifuge. An opening is provided in the bottom of the chute intermediate its ends. Thus, bar ends, and other large pieces of metal which may be included in said mixture, will drop through the opening while air being drawn into the chute through the opening by the centrifuge will entrain the metal chips to prevent their dropping out of the opening and continue onward through the chute into the centrifuge.

摘要： The charge well of a metal melting furnace is provided with an internal cavity having a circular cross section when viewed from the top, preferably a cavity of cylindrical or conical configuration, and with a peripheral exit port located tangentially with respect to said cavity at a lower level thereof for exit of molten metal into the main chamber of the furnace. An inert gas bubble-actuated molten metal pump brings molten metal from a hotter section of the furnace, advantageously directly from the main chamber, and has its exit port located tangentially to the periphery of the cavity at an upper level thereof, thereby creating vortical flow of molten metal within the charge well for the more rapid and efficient melting of metal chips and scraps into the molten metal therein and for circulation of hotter molten metal throughout the furnace. A head of molten metal can be created in the charge well, which advantageously has an exit port of restricted internal cross-sectional area, to assist with attainment of these objectives. A heat and flame-resistant cover may be located above the cavity and advantageously has an aperture therein for the loading of metal chips or scrap thereinto. A gravity-feed chip charger may surmount the aperture for the discharge of new metal chips or scrap into the cavity through the said aperture.

摘要： Utilization of metal chips, especially scrap metal chips, particularly brass and aluminum, by introduction of the metal chips into a pool of molten metal of which they are formed or an alloy thereof, with minimization of fuel cost, heat loss, and minimal conversion of the metal at the surface of the molten metal pool to metal oxide, as well as an increase in the yield of utilizable metal from the remelting or recycling operation, by maintaining a non-oxidizing atmosphere at the surface of the molten metal pool and optionally utilizing vaporized residual impurities from chips being recycled such as oil, lacquer, or similar vaporizable impurity to assist in maintaining the non-oxidizing atmosphere, thereby permitting elimination of impurity-removal steps previously required for preparation of the chips for recycling by introduction into such a molten metal pool, and thereby also conveniently and simultaneously substantially reducing environmental pollution from vaporizable contaminants, fumes, and decomposition products of combustion thereof. Apparatus for use in the process, including a furnace charge-well cover and associated hood, is also disclosed.
