Problems solved by technology

[0002] At present, the aluminum-silicon alloys on the market have high impurity content, serious composition segregation, poor mechanical and processing properties, poor raw material sorting ability, high preparation cost and low efficiency.
[0003] In addition, the preparation method adopted by the high-purity stable aluminum alloy ingots currently on the market is to use pure aluminum ingots as the base, add the required alloying elements according to the composition ratio requirements, and smelt the aluminum alloy ingots of the required grades. However, the cost of this preparation method is very high; another preparation method is to use waste aluminum materials to prepare, use recycled waste aluminum parts or scraps and waste aluminum wires in the process of producing aluminum products as the main raw materials, and produce them through smelting and preparation. To produce secondary aluminum ingots that meet the standard requirements, this production method has the following problems:
[0008] At present, the high-temperature smelting method is generally adopted in the industry, and the temperature is controlled at about 800°C during the smelting process. This kind of smelting causes a lot of burning damage to raw...
