Embodiment Construction

[0007] In order to make the purpose of the present invention, technical solutions and advantages clearer, the present invention will be described in further detail below,

[0008] The embodiment of the present invention provides a performance optimization process for casting Al-10Mg alloy, the raw materials of the casting Al-10Mg alloy include: industrial pure Al, industrial pure Mg and Al-RE master alloy containing 15% Re, Al-RE Mixed rare earths are added to the master alloy, and the components of the mixed rare earths are 55% Ce, 30% La, 10% Y, and 5% Sc.

[0009] The process of adding mixed rare earths to the Al-RE master alloy is as follows. The Al-RE master alloy is smelted in a well-type electric furnace with a graphite crucible. The melting temperature is controlled at 780°C. For a good mixed rare earth, stir it well and keep it warm for 2 hours, then remove the slag and cast it.
