Patent number: 11953424Abstract: A method for the surface treatment of flat products made of aluminium alloys. The method includes pickling the flat product, in particular for degreasing the flat product. The method includes carrying out a colour measurement on the surface of the flat product to determine at least one measured colour value after pickling the flat product. The method includes generating output information on the basis of the at least one measured colour value. The output information is indicative of compliance with at least one rule for the measured colour value and outputting or triggering the output of the output information. The invention further relates to a device for the surface treatment of flat products made of aluminium alloys and to a use of a colorimeter which is configured to determine at least one measured colour value in a surface treatment of flat products made of aluminium alloys.Type: GrantFiled: October 22, 2021Date of Patent: April 9, 2024Assignee: SPEIRA GMBHInventors: Dirk Zentzis, Gernot Nitzsche, Kathrin Eckhard

Patent number: 11807027Abstract: The present disclosure provides an aluminium alloy strip for lithographic printing plate supports, which has a rolled-in surface topography on one strip surface. Further, a method is disclosed for manufacturing the aluminium alloy strip and a printing plate for lithographic printing, with a printing plate support made of aluminium alloy. The object of proposing an aluminium alloy strip for lithographic printing plate supports is that it provides a long service life in the printing process and is roughened with less charge support entry. This is achieved in that the surface of the aluminium alloy strip has a mean peak number measured perpendicular to the rolling direction of the aluminium alloy strip.Type: GrantFiled: September 14, 2022Date of Patent: November 7, 2023Assignee: Speira GmbHInventors: Oliver Bauer, Gernot Nitzsche, Volkan Barisik, Vera Bartosinski, Jasmin Dahmen, Klaus Weichbrodt, Jan Hendrik Holtz

Patent number: 11673184Abstract: A strip casting system for aluminium and/or aluminium alloys comprising a casting furnace and a revolving chill mould having a casting gap. The revolving chill mould is designed as a roll pair, roller pair, caterpillar pair or belt pair. The strip casting system has an active means for transporting metal melt from the casting furnace to the casting gap and a casting region arranged in front of the casting gap. The casting region is delimited on one side by the revolving chill mould. A melt pool is formed in the casting region, from which metal melt flows or is drawn into the casting gap. The casting furnace is connected to the casting region by a pipe system with means for feeding the metal melt into the casting region, which can feed the metal melt to the casting region below the surface of the melt pool formed in the casting region.Type: GrantFiled: December 28, 2021Date of Patent: June 13, 2023Assignee: Speira GmbHInventors: Kai-Friedrich Karhausen, Ralph Bock, Manfred Langen, Wolfgang Müller, Mark Badowski

Publication number: 20230078028Abstract: The present disclosure provides an aluminium material for the manufacture of high-strength, soldered components, including an aluminium alloy. After soldering, the aluminium material is in materially-bonded contact with at least one solder layer. The object of providing an aluminium material is to provide not only good soldering properties and formability, but also high strength. This is achieved because the aluminium alloy of the aluminium material has a solidus temperature, and the aluminium material has an increase in yield strength compared to the state after soldering and cooling.Type: ApplicationFiled: September 15, 2022Publication date: March 16, 2023Applicant: Speira GmbHInventors: Martin Christoph Lentz, Nico Eigen, Volker Sass
