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.

Patent number: 6602461Abstract: An arrangement for pouring a pourable melt made up of a copper alloy, which comprises a melting furnace, pivotable about a horizontal pivot axis, having a pouring tube which discharges pourable melt and through which the pourable melt can be conveyed under a shielding gas atmosphere to a filling end of a launder and can be conveyed through an outlet of the launder to a mold. The filling end of the launder is coverable by a hood that seals off the pourable melt from the atmosphere, the pouring tube engaging, with interposition of a seal arrangement, in pivotably movable fashion into the hood. As a result, the pourable melt can be transferred into the launder under a shielding gas atmosphere upon pivoting of the melting furnace and the pouring tub.Type: GrantFiled: March 14, 2002Date of Patent: August 5, 2003Assignee: KM Europa Metal AGInventors: Andreas Krause, Dirk Rode, Meinhard Hecht, Thomas Helmenkamp, Uwe Quadfasel, Ralph Frankenberg, Hubertus Brüning
