Patent number: 8051893Abstract: A liquid-cooled permanent chill mold for the continuous casting of metals, including a permanent chill mold plate (2) made of copper or a copper alloy and an adapter plate (3), on which the permanent chill mold plates (2) are fastened via fastening bolts (12). The permanent chill mold plates (3) are coupled to the adapter plates (3) via sheet metal holders (19) situated in their top regions and base regions (20, 21), in addition to via the fastening bolts (12).Type: GrantFiled: October 31, 2008Date of Patent: November 8, 2011Assignee: KME Germany AG & Co. KGInventors: Hans-Günter Wobker, Gerhard Hugenschütt, Thomas Rolf

Patent number: 8039097Abstract: A method for the temporary protection of patinated surfaces of copper products, in which an aqueous polymer dispersion is applied to the patinated surface, so that the polymer dispersion penetrates regions of the porous patina that are close to the surface, and in which the aqueous polymer dispersion is subsequently dried, so that it forms a composite with the patina that is permeable to water vapor diffusion. The polymer dispersion binds loose dust located on prepatinated copper products and simplifies the handling of the copper products. It behaves in a hydrophobic manner, but on the other hand it permits the required access of air moisture and water to the patina layer for further weathering.Type: GrantFiled: November 8, 2007Date of Patent: October 18, 2011Assignee: KME Germany AGInventor: Stefan Hoveling

Publication number: 20110206946Abstract: A method for producing a carbon nanotube-, fullerene- and/or graphene-containing coating on a substrate includes the steps of applying carbon nanotubes, fullerenes and/or graphenes onto a tin-containing coating and introducing carbon nanotubes, fullerenes and/or graphenes into the coating by mechanical and/or thermal treatment. A coated substrate produced by this method and the use of the coated substrate as an electromechanical component or lead frame are also described.Type: ApplicationFiled: September 3, 2009Publication date: August 25, 2011Applicants: KME GERMANY AG & CO. KG, TYCO ELECTRONICS AMP GMBH, WIELAND-WERKE AKTIENGESELLSCHAFTInventors: Helge Schmidt, Isabell Buresch, Udo Adler, Dirk Rode, Sonja Priggemeyer

METHOD FOR PRODUCING CAST MOLDED PARTS AS WELL AS CAST MOLDED PARTS PRODUCED ACCORDING TO THE METHOD
Publication number: 20110056646Abstract: The invention relates to a method for the production of castings made of a copper alloy comprising silicon, nickel, chromium, and zirconium, and also inter-metal primary phases, wherein an ingot is drawn by means of hot forming in only one direction at a ratio of at least 4:1, wherein a casting surface of a casting produced from the drawn ingot, said surface coming into contact with a metal melt, is substantially selected perpendicular to the drawing direction of the ingot. A casting produced in this manner is characterized by high wear resistance and increased service life, particularly when used as a block of a side bank of a double strip casting system.Type: ApplicationFiled: March 19, 2009Publication date: March 10, 2011Applicant: KME GERMANY AG & CO. KGInventors: Thomas Helmenkamp, Dirk Rode, Markus Niemann -
Patent number: 7510615Abstract: An age-hardening copper alloy made of—as expressed in each case in weight %—0.4% to a maximum of 2% cobalt which is partially replaceable by nickel, 0.1% through 0.5% beryllium, optionally 0.03% through 0.5% zirconium, 0.005% through 0.1% magnesium and possibly a maximum of 0.15% of at least one element from the group including niobium, manganese, tantalum, vanadium, titanium, chromium, cerium and hafnium. The remainder is copper inclusive of production-conditioned impurities and usual processing additives. This copper alloy is used as the material for producing casting molds, in particular for the sleeves of continuous casting rolls as components of a two-roll casting installation.Type: GrantFiled: November 13, 2002Date of Patent: March 31, 2009Assignee: KME Germany AG & Co. KGInventors: Dirk Rode, Thomas Helmenkamp, Fred Riechert

Patent number: 7467656Abstract: A liquid-cooled permanent mold for the continuous casting of metals, comprising mold plates (1) made of copper or a copper alloy, which are connected respectively to an adapter plate or a water-cooling tank by clamping bolts, the clamping bolts being fastened to plateau pedestals (3) that protrude in an insular fashion from the coolant side (2), which at least partially extend into a coolant gap formed between the mold plate (1) and the adapter plate or the cooling-water tank, and have a streamlined form adjusted to the flow direction of the coolant. The coolant side (2) has cooling ribs (4, 5, 6, 7) that extend into the coolant gap and are situated from place to place between two adjacent plateau pedestals (3).Type: GrantFiled: June 6, 2006Date of Patent: December 23, 2008Assignee: KME Germany AG & Co. KGInventors: Hans-Günter Wobker, Gerhard Hugenschütt, Thomas Rolf

Patent number: 7455098Abstract: A permanent chill mold for the continuous casting of metal, having a mold cavity (2) which has a pouring slot (3), an exit opening (4) and a casting cone (6). At least one concave bulging (7) is provided that extends in the casting direction (G), which begins at a distance (A) below a predetermined casting bath level position (5) and extends up to the exit opening (4).Type: GrantFiled: November 29, 2006Date of Patent: November 25, 2008Assignee: KME Germany AG & Co. KGInventors: Hans-Günter Wober, Gerhard Hugenschütt, Dietmar Kolbeck, Raimund Boldt, Frank Maiwald, Daniel Reinelt, Hans-Dirk Piwowar, Dirk Rode
