[0002] Rare earth aluminum alloy strip is an aluminum alloy strip containing rare earth elements. It possesses high strength, hardness, and corrosion resistance, while also exhibiting good plasticity and machinability. The addition of rare earth elements improves the thermal stability and oxidation resistance of the aluminum alloy, allowing it to maintain good performance even at high temperatures.

[0003] Chinese Patent CN116479273A discloses an aluminum alloy containing lanthanum and cerium mixed rare earth elements and its production method. The production method includes the following steps: 1) preparing raw materials; 2) melting aluminum ingots in a smelting device to obtain molten aluminum; 3) sequentially adding rare earth alloy, titanium-boron alloy, and aluminum-lanthanum-cerium intermediate alloy to the molten aluminum and stirring until melting; 4) adding a slag remover; 5) adding an Al-Ti-B refining agent, stirring until melting, and casting to obtain a rare earth alloy ingot; 6) homogenizing the rare earth alloy ingot; 7) solution treating the homogenized rare earth alloy ingot at 520-550℃ for 2-5 hours, followed by direct water quenching; 8) extruding the water-quenched rare earth alloy ingot according to the set shape and size, and then aging it to obtain an aluminum alloy strip containing lanthanum and cerium mixed rare earth elements.

[0051] S6 and motor c36 operate, pushing the billet into the heat treatment furnace 38 through pusher plate 35.

A production method of the rare earth aluminum alloy strip production apparatus according to claim 6, characterized by, The method comprises the following steps: S1, a certain amount of aluminum powder and a certain amount of rare earth powder are put into the barrel b (10) together, and then the electric control door (11) is closed; S2, the motor a (6) is started to drive the barrel a (9) to rotate, the barrel b (10) is self-rotated through the meshing of the bevel gear a (15) and the bevel gear b (16), that is, the barrel b (10) is self-rotated while being turned over, and the aluminum powder and the rare earth are quickly and uniformly mixed; S3, after the barrel a (9) is rotated to the state that the opening faces downward and then stopped, the electric control door (11) is opened, the vibration motor a (20) and the motor b (32) work, the mixed powder falls on the elastic material guiding plate (19), and then falls on the transition material guiding plate (34) in the inclined state through the discharging groove (22) and finally slides into the strong pressure groove in the lower die (26), the vibration motor a (20) stops working, and the transition material guiding plate (34) is restored to the vertical state again; S4, the vibration motor b (29) starts, through the up and down vibration will strong pressure groove inside the mixed powder evenly flat, vibration motor b (29) stop working; S5, the hydraulic lifting device (3) drives the box body (2) and the upper die (23) to descend, the upper die (23) and the lower die (26) are closed to press the mixed powder into a dense plate-shaped blank, the upper die (23) moves away upwardly, and the stretchable device (28) lifts the blank; S6, the motor c (36) works, through the push plate (35) to push the blank into the heat treatment furnace (38), heat to a certain temperature for a period of time, and then continue to heat to the solid solution temperature, take out the blank for rapid cooling, improve the hardness and strength of the rare earth aluminum alloy, and then put back into the heat treatment furnace (38) for annealing treatment, eliminate stress concentration and improve the structure of grain boundary.
