It is set to 700 DEG C；
（3）Magnetic valve 29 is opened using control cabinet 21, melt is enabled aluminum alloy to and is injected by mozzle 18 in insulating tube 4, screw rod is lived
Cooling water is connected with inside plug 25, melt composition chilling action, buncher 5 can be driven screw-plunger 25 to rotate, seen to melt
Shear action is formed, melt forms that primary phase is tiny and the storage of uniform semi solid slurry under the Quench of screw-plunger 25 and shearing
Exist in insulating tube 4；
（4）After semi solid slurry preparation is finished, hydraulic cylinder 11 is opened, promotes piston screw 25 descending, makes the interior of semi solid slurry
Portion's pressure increase, when pressure increases to the arranges value of pressure valve 30, pressure valve 30 is pressed off, and semi solid slurry uniformly flows out,
It is coated in workpiece surface；
（5）After slurry extrusion completely, the temperature of adjustment insulating tube 4 is 680 DEG C, increases the speed of cooling water, repeats the above steps
1-4, due to shear temperature reduction and the increase of cooling velocity, increases the primary Si particles in semi solid slurry, i.e. hard
Grain increases, and material is thus formed tissue from center portion to the part of surface gradually transition, part is had preferable center portion toughness plasticity
And surface abrasion resistance, the position of servomotor I1, servomotor III20 then adjustment work platform 19 is adjusted by control cabinet 21,
Servomotor II adjusts the position of movable beam 6, reaches the requirement on coating different shape surface.
The rotating speed of buncher 5 is adjusted at 125-1230 revs/min, make the rotating speed of piston screw 25 turn in 125-1230/
Minute, it can also reach and prepare effect well.
