In order to investigate the influence law of homogenization process of hot-rolled 1xxx aluminum alloy on the microstructure and properties, the microstructure of the alloy was characterized by metallographic microscope and scanning microscope. It was found that under the homogenization condition of 580 °C×12 h, with the extension of the holding time, the grain size of 1xxx aluminum alloy continuously grew and the second phase gradually dissolved. The hardness reaches its peak at 12 h. By comparing the microstructure and properties of the finished aluminum foil produced by the two homogenization processes of 580 °C×12 h and 580 °C×6 h, it was found that extending the holding time had a relatively small effect on the grain size of the finished aluminum foil, but it was beneficial to reduce the size and area proportion of the second phase, thereby improving the elongation of the finished aluminum foil.

In order to further investigate the melt flow and solidification heat transfer law in the molten pool during casting and rolling, reveal the generation mechanism of cracks and other defects of cast-rolled 6061 aluminum alloy, and provide reliable theoretical guidance for improving the cast-rolled 6061 sheet, a coupling model of casting roll-cooling water-molten pool was established by using three-dimensional modeling software SolidWorks. The heat transfer and cooling between molten pool, cooling water and casting roll are described, and the heat transfer equations and boundary conditions required for simulating each physical site are determined. The periodic distribution of temperature field and flow field in molten pool is reflected in the form of cloud diagram and flow diagram. The influence principle of casting billet quality is discussed, and the accuracy of calculation is proved by experiments. The results show that the surface eddy current makes the height of Kiss point different in the direction of the width of the molten pool, the exit temperature of the edge is 239.6 ℃, and the exit temperature of the central part is 301 ℃. The center and edge Kiss points are low, and these parts are prone to cracks. The maximum speed of the flow line at the rod sleeve is 16.94 m/s, and due to the difference in the inflow Angle of the cooling water, under the rotation of the casting roll, the flow rate of the cooling water changes alternately in the direction of the circumference of the casting roll according to 1/4 cycle, and the cooling temperature difference between the two adjacent cycles is about 30 ℃.
