Patent number: 11945008Abstract: A method for cleaning rollers used for metal strip processing. According to said method, the roller surface is cleaned by an aqueous alkali metal hydroxide or alkaline earth metal hydroxide washing liquid or an acidic washing liquid, the washing liquid is removed and the roller surface is dried. A machine for cleaning rollers includes a washing frame designed for positioning a roller to be cleaned, and at least one means for applying at least one washing solution to the roller surface of the roller to be cleaned.Type: GrantFiled: September 25, 2020Date of Patent: April 2, 2024Assignee: Hydro Aluminum Rolled Products GmbHInventors: Kathrin Eckhard, Olaf Güßgen, Frank Hirschmann

Patent number: 11260439Abstract: The invention relates to an aluminum alloy strip with improved surface optics, which is fabricated via hot and/or cold rolling, and consists of a type AA 3xxx, AA 5xxx, AA 6xxx or AA 8xxx aluminum alloy. The object of proposing an aluminum alloy strip that is suitable for attractive and precious surface optics despite the elevated percentage of alloy constituents is achieved in that, after degreasing, the finish-rolled aluminum alloy strip exhibits an increase in the luminance value L*(?L) in relation to the rolled-greasy state of more than 5 while measuring the color of the surface in the CIE L*a*b* color space using a standard illuminant D65 and a normal observation angle of 10°, excluding direct reflection in 45°/0° geometry.Type: GrantFiled: July 31, 2014Date of Patent: March 1, 2022Assignee: Hydro Aluminium Rolled Products GmbHInventors: Dieter Bögershausen, Jochen Schwarz, Bernhard Kernig, Kathrin Eckhard, Axel Blecher, Olaf Güßgen

Patent number: 10773325Abstract: Use of an aluminium composite material in a thermal joining method, said material consisting of at least one aluminium core alloy and at least one external brazing layer consisting of an aluminium brazing alloy provided on one or both sides of the aluminium core alloy, wherein the aluminium brazing layer has a pickled surface. Reduced costs and a lower environmental impact is achieved by using an aluminium composite material in which the pickled surface of the aluminium brazing layer had been pickled by pickling with an acid, aqueous pickling solution containing at least one mineral acid and at least one complex-forming agent or a complexing mineral acid, wherein the removal of material in the pickling is between 0.05 g/m2 and 6 g/m2, the aluminium composite material is used in a flux-free, thermal joining method, and the joining method is carried out in the presence of a protective gas.Type: GrantFiled: June 9, 2016Date of Patent: September 15, 2020Assignee: Hydro Aluminium Rolled Products GmbHInventors: Kathrin Eckhard, Olaf Güßgen, Hartmut Janssen

Publication number: 20200238195Abstract: Disclosed is a method for the recovery of filtering agents and rolling oil from a mixture containing used rolling oil and filtering agents coated with used rolling oil in which the mixture containing rolling oil and filtering agents is subjected to vacuum distillation under agitation in a reactor equipped with an agitator and vapour precipitator. The vacuum during distillation is regulated with an inert gas flow, the rolling oil is condensed and collected, and a rolling oil which can be reused for rolling and a powder filtering agent which can be reused are obtained.Type: ApplicationFiled: April 17, 2020Publication date: July 30, 2020Applicant: Hydro Aluminium Rolled Products GmbHInventors: Stephan Draese, Olaf Güßgen, Oliver Seiferth
