Magnetic stirring stops；4th step of cycle：Source emission head is put into smelting furnace, sound duration t2 takes out source emission
Head；Then the first step of cycle is entered back into, the sound that the inside of the source emission head is sent out is the recording that the cicada cried, the sound
Volume energy density be 500 watts to 1000 watts every cubic metre, the computational methods of the volume energy density of the sound are sound
The volume of total metal fluid in the general power divided by smelting furnace of source emitting head.
As a preferred embodiment of the above technical solution, the working cycles are repeated 2 times above, complete stirring；The sound source
The horizontal position that emitting head is placed is the symmetrical centre of smelting furnace, is put into 12 centimetres of vertical positions below below metal fluid liquid level
It sets；The angular frequency w is that 60-100 circles are per minute；The mixing time is that t1 is 5 to 10 minutes；The sound go
Time is that t2 is 5 to 10 minutes.
As a preferred embodiment of the above technical solution, the gas that the rotation degasification described in step 2 uses can be nitrogen or argon
Gas.
The beneficial effects of the present invention are：By the composition design to alloy, multicomponent mutually acts synergistically, and significantly carries
The high intensity of alloy, and maintain certain plasticity and excellent casting character.Such as：The present invention Si constituent contents be
8.0%~9.0%, belong to hypoeutectic cast aluminium alloy gold, there is preferable mobility and casting character；Mg has strongly in Al
Solution strengthening effect, while Mg can with Si formed intermetallic compound Mg2Si has the function of dispersion-strengtherning, hence it is evident that improves
The yield strength of material；Mobility can be improved in Zn, improves mechanical property, improves yield strength；Fe elements under certain condition can
Coarse Fe-riched phase is formed, the plasticity of material is damaged, but Fe can reduce the sticking to mould tendency of alloy in press casting procedure, so die casting aluminium
Alloy all contains a certain amount of Fe mostly, and Fe contents are limited within 0.7%~0.8% by the present invention, slightly below traditional
ADC12 pack alloys；Mn can improve corrosion resistance and intensity, and it is fine and closely woven that suitable Mn can make acicular Fe-Al that can be changed into
Fe-Mn-Al, reduces adverse effect of the iron to mechanical property, and Mn can also reduce sticking to mould tendency when aluminium alloy compression casting；Cu elements
With apparent solution strengthening effect, Cu and Al can form intermetallic compound Al2Cu plays the role of dispersion-strengtherning；Ti exists
Heterogeneous forming core base, crystal grain thinning can be used as to play the role of refined crystalline strengthening in aluminium alloy.
The alloy of the present invention has reached good reinforcing effect using multicomponent cooperative reinforcing, also avoids each constituent element and contains
It is adversely affected caused by amount is excessive.This alloy has obvious ageing strengthening effect, since die casting cooling velocity is fast, Al matrixes
In can be dissolved a large amount of solute atoms, such as Si, Mg, Cu, in the storage and transportational process of structural member, it may occur that when natural
