Patent number: 8312916Abstract: Method and apparatus employing a casting mould including a liquid feed end for supplying the casting mould with molten second alloy and an exit end with an outlet for casting molten second alloy downwardly. While continuously moving the mould and an elongated solid first alloy substrate relative to one another, casting molten second alloy passes downwardly through at least one outlet of the mould onto an upper surface of the substrate at a temperature wherein the substrate locally at least partly remelts beginning at a reference point of a remelting zone and mixes at least partly with molten second alloy to form an alloy pool. After remelting the molten alloy pool continuously cools and solidifies at a location away from the reference point and joins the substrate to form composite ingot including at least two separately formed layers of one or more alloys before discharging from the mould.Type: GrantFiled: June 3, 2009Date of Patent: November 20, 2012Assignee: Aleris Aluminum Koblenz GmbHInventors: Joost Christiaan Storm, Andreas Ten Cate, Ingo Günther Kröpfl, Achim Bürger

Patent number: 8152943Abstract: Manufacturing heat-treatable wrought metal plate having length, width and thickness directions and an engineering properties gradient along at least one plate dimension. Rolled, extruded or forged wrought metal plate is solution heat treated and rapidly cooled. The cooled plate is aged by heat treatment for time to arrive at different tempers across at least one plate dimension (length or width). Controlled heat-input into the plate along its length direction raises plate temperature above ambient temperature to temperature T1, and a temperature gradient is applied between temperature T2 and T3, wherein T2>T3, across at least one direction of the plate by controlled heat-input into the plate from one side (width or thickness) of the plate to temperature T2 and controlled cooling to temperature T3 from the plate at the opposite side of the controlled heat-input, and ageing the plate while applying the temperature gradient between T2 and T3.Type: GrantFiled: September 20, 2008Date of Patent: April 10, 2012Assignee: Aleris Aluminum Koblenz GmbHInventors: Andreas ten Cate, Sunil Khosla, Achim Büerger, Sabine Maria Spangel

Patent number: 7955414Abstract: A method and device for the purification and separation of purified metal from a metal mother liquid having a specific density and comprising one or more foreign element(s). The method includes: providing in a column device a starting material including metal crystals and a metal mother liquid including at least one foreign element; applying a temperature difference between a relatively hot zone at the upper end of the column and a relatively cool zone at the lower end of the column; a separation step wherein at least a part of the metal crystals is separated from the metal mother liquid by rising of the metal crystals to the upper surface of the metal mother liquid; and a further separation step wherein purified metal floating on the upper surface of the metal mother liquid is discharged from the column device.Type: GrantFiled: July 5, 2007Date of Patent: June 7, 2011Assignee: Aleris Switzerland GmbHInventors: Huibrecht Adriaan Wouters, Andreas Ten Cate, Elisabeth Maria Beunder, Willem Boender, Marcellus Albertus Hogenboom, René Kieft, Joost Christiaan Storm

Patent number: 7892318Abstract: Method for purifying molten metal having a specific density and including one or more foreign elements to be removed, by (a) cooling the molten metal to a eutectic temperature to simultaneously form purified metal crystals and crystals including at least one foreign element, and (b) separating at least some of the purified metal crystals from the crystals including at least one foreign element by adjusting the molten metal specific density within a range delimited by a lower value being specific density of the purified metal crystals and an upper limit being specific density of the crystals including the at least one foreign element. The molten metal specific density is adjusted to this range by addition of a metal to alter the molten metal specific density and maintained within this range during separation. The method is advantageously applicable for purification of aluminium melts from recycle aluminium and aluminium scraps.Type: GrantFiled: June 8, 2007Date of Patent: February 22, 2011Assignee: Aleris Switzerland GmbH c/o K+P TreuhandgesellschaftInventors: Huibrecht Adriaan Wouters, Andreas Ten Cate, Elisabeth Maria Beunder, Willem Boender, Marcellus Albertus Hogenboom, René Kieft, Joost Christiaan Storm
