Studying carefully the stage, its Technology need to improve.Present stage semi-solid forming development bottleneck is mainly: 1) prepare semi solid slurry work
Skill poor stability, preparation cost is higher；2) semi solid slurry transfer difficulty is bigger, it is impossible to make semi solid slurry transfer to smoothly
Mould is processed molding.
Summary of the invention
For the deficiencies in the prior art, a kind of method that it is an object of the invention to provide aluminium alloy semi-solid extrusion casint
And system.The method is with aluminium alloy as raw material, through preparing at vacuum melting furnace melting, slurry, extruded, closes improving aluminum
The mechanical property of gold copper-base alloy.The present invention proposes preparation method of semisolid state slurry thereof and the system of a kind of simplicity, the most also realizes half solid
State slurry automatic casting, quantitative pouring, solve slurry transport difficulties during semi-solid forming, reduce semisolid simultaneously
Slurry preparation cost.
For achieving the above object, the present invention is by the following technical solutions:
A kind of method of aluminium alloy semi-solid extrusion casint, comprises the steps:
Step one, aluminium alloy pretreatment: be coated with aluminium foil respectively after first aluminium alloy block is cut into aluminium alloy small blocks,

Compression mould, carries out extruded process；
Step 5, the demoulding cools down: continues pressure after described extruded process completes, ejects foundry goods afterwards, air cooling,
Obtain aluminium alloy semi-solid squeeze casting eventually.
The know-why of the present invention is: 1) using bending channel or inverted-cone shape passage, be preferably as the criterion serpentine channel legal system
Standby metal semi-solid slurry, technique is simple, and preparation cost is relatively low, utilize quasi-serpentine channel from stirring action, smash dendrite；With
Time quasi-serpentine channel cast gate temperature relatively low, aluminium alloy obtains bigger degree of supercooling, a large amount of forming cores, crystal grain thinning, finally gives half
Solid size；2) using electromagnetic pump cast, semi solid slurry, under the effect of Lorentz force, is poured into extrusion die profile；More
Preferably, controlled by programmable logic controller (PLC) (PLC), it is achieved automatic casting and quantitative pouring.
In the method for above-mentioned aluminium alloy semi-solid extrusion casint, as a kind of preferred implementation, in step one, described pre-
The temperature of heat be 180-220 DEG C (such as 182 DEG C, 185 DEG C, 188 DEG C, 195 DEG C, 200 DEG C, 205 DEG C, 210 DEG C, 215 DEG C, 218
DEG C), more preferably 195 DEG C-205 DEG C, the time of described preheating be 10-25min (such as 11min, 13min, 15min, 18min,

In the method for above-mentioned aluminium alloy semi-solid extrusion casint, as a kind of preferred implementation, in step 2, described molten
Refining is carried out in medium frequency induction melting furnace, and complete during Frequency Induction Heating, evacuation, argon bottom blowing.
In the method for above-mentioned aluminium alloy semi-solid extrusion casint, as a kind of preferred implementation, the melting bag of step 2
Include the first sub-step and the second sub-step successively carried out, in described first sub-step, be evacuated to described Medium frequency induction melting
Pressure≤10Pa in stove；Heating-up temperature be 580-620 DEG C (such as 582 DEG C, 585 DEG C, 590 DEG C, 595 DEG C, 600 DEG C, 605 DEG C,
610 DEG C, 615 DEG C, 618 DEG C), more preferably 595-605 DEG C；Heat time heating time be 30-45min (such as 31min, 33min,
35min, 38min, 41min, 43min, 44min), more preferably 40min；In described second sub-step, carry out argon bottom blowing, argon
Gas speed is 800-1200C3/ min (such as 810C3/min、830C3/min、850C3/min、900C3/min、950C3/min、
1000C3/min、1150C3/min、1170C3/min、1190C3/min、1200C3/ min), argon speed is preferably 1000C3/
Min, in making medium frequency induction melting furnace, pressure is maintained at 0.045Mpa, now continues to be heated to 680-750 DEG C and carries out melting
(such as 685 DEG C, 690 DEG C, 695 DEG C, 700 DEG C, 710 DEG C, 720 DEG C, 730 DEG C, 735 DEG C, 740 DEG C, 745 DEG C), more preferably heat
