20150139852 | PROCESS AND APPARATUS FOR DIRECT CHILL CASTING - A system comprising at least one furnace including a melt containing vessel; an intermediate casting product station coupled to the at least one furnace and operable to receive a molten metal from the at least one furnace, the intermediate casting product station including a casting pit, at least one moveable platen disposed in the casting pit, an array of exhaust ports about at least a top periphery of the casting pit, and an array of gas introduction ports about at least the top periphery of the casting pit; and an inert gas source operable to supply an inert gas to the array of gas introduction ports. | 05-21-2015 |
20150078959 | PROCESS AND APPARATUS FOR MINIMIZING THE POTENTIAL FOR EXPLOSIONS IN THE DIRECT CHILL CASTING OF ALUMINUM LITHIUM ALLOYS - Steam exhaust ports are located around a perimeter of a direct chill casting pit, at various locations from below the top of the pit to the pit bottom to rapidly remove steam from the casting pit with addition of dry excess air. Gas introduction ports are also located around a perimeter of the casting pit and configured to introduce an inert gas into the casting pit interior. | 03-19-2015 |
20140238197 | SIMULTANEOUS MULTI-MODE GAS ACTIVATION DEGASSING DEVICE FOR CASTING ULTRACLEAN HIGH-PURITY METALS AND ALLOYS - An “in-line” device to continuously remove dissolved gasses from liquid metal is described. The device described herein may contain an apparatus to create a partial vacuum, one or more ultrasonic vibrators below the surface of the liquid metal to evolve gas bubbles within the metal, and a high-frequency vibrating metal plate which the fluid must pass over at a low depth. The device may be used to create high quality metals, including aluminum and aluminum alloy for a number of demanding applications such as pharmaceutical, semiconductor, foil, and aerospace applications including Aluminum-Lithium alloys. | 08-28-2014 |
