METHOD FOR MAKING ALUMINIUM ALLOY STRIPS BY CONTINUOUS THIN GAUGE TWIN-ROLL CASTING AND ALUMINIUM STRIP

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....

Beschreibung
Zusammenfassung:	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.
