[0023] in figure 2 , image 3 Medium: A method for preparing an alloy ingot containing magnesium and cerium, which mainly includes the following steps:
[0024] Step ①, ingredients:
[0025] A magnesium-cerium-containing alloy ingot. The alloying elements are proportioned according to weight percentages: aluminum 20% to 25%, silicon 0.2% to 0.3%, magnesium 1.1% to 1.9%, rare earth cerium 0.5% to 0.6%, The balance is zinc;
[0026] Step ②, smelting:
[0027] Put the proportioned metal into the smelting furnace, heat it up to 650 degrees, combine magnetic stirring and manual stirring to make the components uniformly alloyed to avoid aluminum segregation, remove the scum from the inner surface of the furnace, and then sample at the furnace mouth , Laboratory tests whether the ingredients are uniform;
[0028] Step ③, pouring: the pouring time should not be too fast, otherwise it is easy to produce bubbles, slag inclusions, and cracks. The pouring is 3 minutes. After pouring, the surfac...
