Title (EN) METHOD FOR MAKING ALUMINIUM ALLOY STRIPS BY CONTINUOUS THIN GAUGE TWIN-ROLL CASTING
(FR) PROCEDE DE FABRICATION DE BANDES EN ALLIAGES D'ALUMINIUM PAR COULEE CONTINUE MINCE ENTRE CYLINDRES
Abstract:
(EN) The invention concerns a method for making aluminium alloy strips containing (by weight) at least 0.15 to 1.5 % Fe and/or 0.35 to 1.9 % Mn, with Fe + Mn < 2.5 % and optionally Si < 0.8 %, Mg < 0.2 %, Cu < 0.2 %, Cr < 0.2 %, Zn < 0.2 %, and other elements each < 0.1 % and < 0.3 % in all, by continuous casting between two cylinders cooled and wire bound to a thickness ranging between 1 and 5 mm, the force applied to the cylinders during casting, expressed in tons par meter of strip width, being less than 300 + 2000/e, e being the cast strip thickness in mm. The invention also concerns strips in alloy of the same composition twin-roll cast between 1 and 5 mm thick and having a product R0.2 (MPa) x A (%) greater than 2500, and preferably than 3000.
(FR) L'invention concerne un procédé de fabrication de bandes en alliage d'aluminium contenant (en poids) de 0,15 à 1,5 % Fe et/ou de 0,35 à 1,9 % Mn avec Fe + Mn < 2,5 %, et éventuellement Si < 0,8 %, Mg < 0,2 %, Cu < 0,2 %, Cr < 0,2 %, Zn < 0,2 %, autres éléments < 0,1 % chacun et < 0,3 % au total, par coulée continue entre deux cylindres refroidis et frettés à une épaisseur comprise entre 1 et 5 mm, l'effort appliqué aux cylindres pendant la coulée, exprimé en tonnes par mètre de largeur de bande, étant inférieur à 300 + 2000/e, e étant l'épaisseur de la bande coulée en mm. Elle concerne également des bandes en alliage de même composition coulées en continu entre 1 et 5 mm d'épaisseur et présentant un produit R0,2 (en MPa) x A (en %) supérieur à 2500, et de préférence à 3000.
