  • Patent number: 11408062
    Abstract: A method for heat treating cast aluminum alloy components that includes obtaining a casting formed from an aluminum alloy having a silicon constituent and at least one metal alloying constituent, and heating the casting to a first casting temperature that is below but within 10° C. of a predetermined silicon solution temperature at which the silicon constituent rapidly enters into solid solution. The method also includes increasing the rate of heat input into the casting to raise the temperature of the casting to a second casting temperature that is above but within 10° C. of a predetermined alloying metal solution temperature at which the at least one metal alloying constituent rapidly enters into solid solution, maintaining the casting at the second casting temperature for a period of time that is less than about 20 minutes, and then quenching the casting to a temperature less than or about 250° C.

  • Patent number: 11035016
    Abstract: A quench system for applying cooling air to one or more hot metallic components that are supported on a component support having a substantially open construction. The quench system includes a housing having sidewalls that define a cooling chamber with peripheral portions proximate the sidewalls and a center portion spaced inwardly from the sidewalls. The quench system also includes a conveyance system that is configured to carry the component support into the center portion of the cooling chamber, as well as a forced air fan that generates a bulk flow of cooling air through the cooling chamber. The quench system further includes a plurality of nozzle baffles extending inwardly from the plurality of sidewalls to define a narrowing region within the housing between the forced air fan and the conveyance system, whereby, during operation of the fan, cooling air flowing through the peripheral portions of the cooling chamber is redirected into the center portion of the cooling chamber.

  • Publication number: 20140261904
    Abstract: A system and method for formation and processing of pressurized die cast metal articles or components includes an injection or casting station in which a series of cast metal articles are formed within a series of dies by the introduction of a metal material into the dies. The dies are then moved to a retention area where the metal material is permitted to solidify to form the castings, after which the dies are opened and the castings removed therefrom, and subsequently are transferred to a short cycle solution heat treatment station. The castings are conveyed through the short cycle solution heat treatment station with the castings maintained within a series of fixtures to dimensionally support and stabilize the castings during solution heat treatment thereof.

  • Patent number: 8066053
    Abstract: Disclosed is a method for dislodging a mold from a casting formed within the mold. The mold may be removed from the casting by scoring the mold and applying a force sufficient to cause the mold to fracture and break into pieces. Additionally, the mold may be fractured by either explosive charges placed in the mold pack or by high energy pulsations directed at the mold. Once the mold is fractured and broken into various pieces it may then be dislodged from the casting.

  • Patent number: 7273015
    Abstract: A system for combustion and removal of residual carbon within fly ash particles in which the fly ash particles are fed into an array of process units for combustion. The fly ash particles are subjected to heat and motive air such that as the fly ash particles pass through the particulate bed, they are heated to a sufficient temperature to cause the combustion of the residual carbon within the particles. The fly ash particles thereafter are conveyed in a dilute phase for further combustion through the reactor chamber away from the particulate bed and exhausted to an ash capture. The fly ash is then separated from the exhaust air that conveys the ash in its dilute phase with the air being further exhausted and the captured fly ash particles being fed to a feed accumulator for re-injection to the reactor chamber or discharge for further processing.
