摘要： The invention relates to a hot reversing mill equipped with one or more cooling systems consisting of bars of nozzles spraying an aluminum blank. It also relates to the hot rolling process associated with this hot reversing mill wherein the cooling system serves at least once making it possible to produce aluminum sheets advantageously. It also relates to the process for rolling an AA6xxx series aluminum alloy wherein a blank is cooled during the hot rolling and a sheet obtained with this process. The invention makes it possible to enhance the productivity of reversing mills by enhancing the metallurgical quality and/or the productivity of the other fabrication steps. The invention is particularly useful for providing superior quality 6xxx alloy sheets intended for the automotive industry.

摘要： The present invention is directed to a bottom part of a battery box for electric or hybrid motor vehicles made from an aluminium alloy sheet having a thickness between 2 and 6 mm, wherein said aluminum alloy comprises 2.5 to 4.0 wt. % of Mg, 0.1 to 0.8 wt. % of Mn, 0.4 wt. % or less of Si, 0.5 wt. % or less of Fe, 0.5 wt. % or less of Cu, 0.1 wt. % or less of Cr, 0.1 wt. % or less of Zn, 0.1 wt. % or less of Ti, rest aluminium and unavoidable impurities up to 0.05 wt. % each and 0.15 wt. % total. Another object of the invention is a method to make a bottom part of battery box according to the invention comprising casting said aluminium alloy into a rolling ingot; homogenizing and/or reheating said rolling ingot; hot rolling and optionally cold rolling said rolling ingot to obtain a sheet with a thickness between 2 mm and 6 mm. The bottom part of battery box of the invention is simultaneously light, resistant against intrusion, sufficiently formable and leak tight, corrosion resistant, able to accommodate temperature variations and sufficiently stiff and strong.

摘要： A method of manufacturing a textured-smooth hybrid metal closure cap, and a closing caps produced by the method. The method includes a) the supply of a strip or sheet, made of aluminum alloy known as a “textured” strip or sheet, typically coated on at least one of its faces by a stampable lacquer, b) a first operation for cutting discs, called blanks, c) a step for stamping, in one or more passes, of said blank metal, typically using a stamping lubricant, so as to form a stamped blank, comprising a head and a skirt, typically axially symmetric in the axial direction, d) a step for degreasing said stamped blank, typically intended to eliminate the remaining lubricant, to form a degreased blank that can be lacquered, and e) an optional step of protective lacquering and decoration. After the stamping step, and before the lacquering step, at least one drawing step consisting in passing the stamped blank through drawing rings in order to stretch and thin the metal.
