  • Patent number: 9163302
    Abstract: The present invention relates to a castable heat resistant aluminum alloy for high temperature applications such as components in combustion engines, in particular for the manufacturing of highly loaded cylinder heads, the alloy comprises the following composition: .Si: 6.5-10 wt %.Mg: 0.25-0.35 wt %.Cu: 0.3-0.7 wt %.Hf: 0.025-0.55 wt % Optionally with the addition of: .Ti: 0-0.2 wt %.Zr: 0-0.3 wt %, the balance being made of Al and unavoidable impurities including Fe.
    Type: Grant

  • Patent number: 8561669
    Abstract: Equipment for the semi-continuous direct chill (DC) casting of sheet ingot or slabs of different dimensions, in particular for rolling purposes, including a mold frame (2) with a pair of facing long side walls (3) and a pair of facing short end walls (4). The walls of the mold define an upwardly open inlet for the supply of metal and a downwardly facing outlet provided with a starter block (5) on a movable support which prior to each casting closes the opening. The equipment includes a device for changing the mold dimensions where at least one end wall can be displaced to enable casting of ingots with different sizes, and it further includes a device for indirect and direct cooling of the metal during casting. The equipment also includes apparatus for flexing the long side walls (3) of the mold, thereby enabling adjustment of the flexible middle part of the long side walls (3) inwardly or outwardly to adapt to the desired sheet ingot size, the desired casting speed and/or alloy composition.

  • Patent number: 8413711
    Abstract: A device in connection with equipment for continuous or semi-continuous casting of metal, in particular direct mold (DC) casting of aluminum in the form of a billet or wire billet. The device includes a mold with a cavity or a mold (3) that is provided with an inlet connected, via supply channels (6, 18) and a distribution chamber (5), to a metal reservoir (13) and an outlet arranged in the mold with a support and devices for cooling the metal. In connection with the supply channels (6, 18) between the metal reservoir (13) and the molds (3), a metal lifting container (15) is arranged at an inlet (16) to the metal reservoir (13) via a channel (18) and to the distribution chamber (5) and the molds (3) via an outlet (17) via another channel (6).
