Embodiment 1
[0032] A technical scheme of high-strength aluminum foil alloy for fresh air system produced by a new casting and rolling method, the composition and mass percentage of the alloy are:
[0033] Si 0.20-0.30%, Fe 0.40-0.60%, Cu 0.05-0.25%, Mn 1.4-1.8%, Zn 1.4-1.6%, Ti≤0.03%, and the balance is Al.
[0034] A method for manufacturing a high-strength aluminum foil material for a fresh air system, the steps of the method are as follows:
[0035] (1) Smelting, casting and rolling: DS309 alloy is used internally for smelting and casting and rolling into 6.5-7.5mm cast-rolled aluminum coils; the melting temperature is smelted in the range of 720-760°C, and poured at 720-760°C after melt refining treatment Put it into a static furnace to keep it warm, and the temperature of the static furnace is 720~750°C.
[0036] (2) Rough rolling: rough rolling the billet, rolling the cast-rolled aluminum coil to a thickness of 3.0-5.0mm through 1-3 passes, and then performing intermediate annealin...
Embodiment 2
[0052] The steps of preparing the high-strength aluminum foil material for the fresh air system according to the embodiment of the present invention are as follows:
[0053] 1. Melting Si 0.25%, Fe 0.50%, Cu 0.15%, Mn 1.7%, Zn 1.5% and the rest are aluminum as the basic composition by weight percentage to prepare alloy raw materials;
[0054] 2. Melt the raw materials, the melting temperature is in the range of 720-760 °C, after the melt refining treatment, pour it into the static furnace at 720-760 °C to keep it warm, and the temperature of the static furnace is 720-750 °C; after that, it is obtained by casting and rolling 7.0mm cast and rolled coil;
[0055] 3. After rough rolling, the cast-rolled parent coil is rolled at 7.0mm-5.4mm-4.0mm to a thickness of 4.0mm for intermediate annealing, the temperature is raised to 240°C for 2h and kept for 3h, and the temperature is continued to be raised to 520°C for 4h to cool out of the furnace;
[0056] 4. After the intermediate an...
