Embodiment 1
[0025] The rolling method of the ultra-high-strength aluminum alloy plate of the present invention comprises the following steps:
[0026] A. Homogenize and anneal the Al-Cu-Mg alloy billet after refining at 450°C for 24 hours;
[0027] B. Control the temperature of the Al-Cu-Mg alloy billet after annealing at 360°C. After the temperature inside and outside of the Al-Cu-Mg alloy billet is uniform, perform a single-pass 2% hot rolling pre-deformation, roll rolling The line speed is 0.4m / min, continue to control the temperature of the Al-Cu-Mg alloy billet to 360°C, and then carry out a single-pass 60% large-reduction rolling deformation, and the rolling line speed is 0.4m / min. min, the thick slab is obtained by rolling, and the thick slab is water-cooled or air-cooled;
[0028] C. The cooled thick slab is subjected to solution treatment at 450°C for 0.5h, and then water quenched;
[0029] D. Pre-aging the thick slab after water quenching at 150°C for 6 hours, and then air coo...
