[0015] Example 1
[0016] A method for preparing an aluminum alloy aluminum ingot rich in zinc and zirconium elements includes the following steps:
[0017] a. Put the aluminum ingot into the melting furnace, the temperature of the melting furnace is increased to 740~760℃, and the aluminum ingot is completely melted to form a molten pool and carry out slag extraction;
[0018] b. After slagging, add Mn agent to the furnace; after the Mn agent in the furnace is completely melted, add Si agent, Fe agent and Cu agent to the furnace at the same time; Wait for the Si agent, Fe agent and Cu agent in the furnace to melt completely Then, add Zn ingot and Zr agent to the furnace; after the Zn ingot and Zr agent in the furnace are completely melted, an aluminum alloy mixed melt is obtained;
[0019] c. The temperature of the aluminum alloy mixed melt is controlled at 705~710℃ and then poured into the cavity of the casting mold moving forward at a constant speed for semi-continuous casting. The cas
