The method comprises cast rolling bars (1) from an aluminum-magnesium-silicon (AlMgSi) alloy, where during rolling, the rolling bars are subjected to homogenization, are hot-rolled to a hot-rolling temperature and are optionally cold-rolled to a final thickness. The finished rolled tape is solution-annealed and deterred. The hot-rolled strip has, according to the discharge from the last hot-rolling stitch, a temperature of more than 230[deg] C. The hot-rolled strip is deterred using a circuit board radiator and an emulsion-subjected hot-rolling stitch on a discharge temperature.

The finished rolled tape is solution-annealed and deterred. The hot-rolled strip has, according to the discharge from the last hot-rolling stitch, a temperature of more than 230[deg] C. The hot-rolled strip is deterred using a circuit board radiator and an emulsion-subjected hot-rolling stitch on a discharge temperature. The temperature of the hot-rolled strip: before starting the cooling process is more than 400[deg] C; during the last rolling stitch is more than 250[deg] C; and during the last rolling stitch and before recoiling is 200-230[deg] C. A thickness of the finished hot-rolled strip is 5-8 mm. The finished rolled aluminum strip is subjected to heat treatment, with which the aluminum strip is heated to more than 100[deg] C according to solutionizing and deterring and subsequently rolled up and outsourced with a temperature of more than 85[deg] C. |
