This invention belongs to the field of aluminum-based composite material preparation technology, and relates to a continuous casting and rolling method for preparing aluminum-based composite material strips. The method involves preparing a reinforcing preform with a thickness not exceeding the roll gap distance in the aluminum-based composite material strip. Before preparing the aluminum-based composite material strip, the casting rolls are water-cooled and run at a set speed. Molten aluminum is injected into the molten pool, and the liquid level is controlled to a set value. Throughout the preparation process, the molten pool liquid level is maintained at the set value. The molten aluminum cools and solidifies upon contact with the roll surface of the casting rolls. Under the casting action of the two casting rolls, an aluminum alloy strip is formed and continuously output from the lower end of the roll gap. During the preparation process, the reinforcing preform moves from top to bottom at a set speed and is immersed in the molten aluminum pool. The molten aluminum penetrates into and fills the interior of the reinforcing preform. The reinforced preform, filled with molten aluminum, gradually solidifies as it moves to the roll gap until it is completely solidified. Then, under the casting force of the two casting rolls, it undergoes rolling deformation to form the aluminum-based composite material strip.
