Embodiment 1
[0027] In this embodiment, a production process of an aluminum alloy ingot is characterized in that it includes the following steps:
[0028] a. Ingredients: mix according to the ratio requirements of each element of the product;
[0029] b. Melting: When the hearth of the smelting furnace is dark red, put the proportioned raw materials into the smelting furnace for smelting, and when the temperature of the molten aluminum in the smelting furnace rises to 650°C-750°C, use a permanent magnet aluminum water mixer to stir;
[0030] c. Adding silicon: when the temperature of the molten aluminum reaches 720°C to 740°C, take samples for testing, add a certain amount of metal silicon according to the testing results, and fully stir it with a permanent magnet aluminum water mixer to melt it;
[0031] d. Cooling: When the temperature of the molten aluminum after adding silicon rises to 780°C-820°C, add a cooling material, the cooling material is pure aluminum, so that the temperature o...
