Embodiment 1

[0053] For the transverse vibration rolling process of AA5052 alloy material, the chemical composition mass fraction of AA5052 alloy is 0.09% Si, 0.24% Fe, 0.02% Cu, 0.06% Mn, 2.3% Mg, 0.19% Cr and 0.1% Zn, and the balance is Al , cut it into a sample with a shearing machine, and the rolling process is as follows:

[0054] (1) Put the AA5052 alloy sample into the heating furnace, raise the temperature to 350°C, heat preservation annealing treatment for 1 hour, and then cool to room temperature with the furnace to eliminate the residual stress of the sheet metal and facilitate subsequent transverse vibration rolling;

[0055] (2) Implement transverse vibration rolling on the annealed plate, the rolling temperature is set to 100 °C, the reduction rate of each rolling pass is 40%, rolling 4 times, the transverse vibration frequency of the lower roll is 5Hz , 4-pass rolling amplitude is selected as 1mm, and the total thickness of transverse vibration rolling is reduced by 87%;
