Example Embodiment
[0039] Example 1
[0040] Step 1, remove scale and impurities on the surface of raw materials: use grinding wheels and sandpaper to grind scale and impurities on the surface of raw materials for pure magnesium ingots and master alloy ingots to obtain pure raw material blocks;
[0041] Step 2, weighing: according to weight percentage: Ag 0.1%, La 6%, Ca 0.4%, unavoidable impurity elements <0.01%, magnesium balance. Accurately weigh the raw materials for the preparation of the above-mentioned magnesium alloys. A hole is machined on the pure magnesium ingot, and its size is determined according to the size of the silver ingot particles. It is advisable to cover the hole with a machined piece of magnesium ingot to prevent the pure silver particles from falling;
[0042] Step 3, smelting and casting: place the weighed raw materials in the order of pure magnesium ingot, Mg-25% La master alloy ingot, Mg-25% Ca master alloy ingot and pure magnesium ingot with built-in pure silver parti...
