As a example by hub：About 2.5g/cm2, the density of water is：1g/cm2, that is to say, that water can rise 10mm under 1 millibar of pressure, by
This can show that aluminium liquid can rise the height of 4mm under 1 millibar of pressure.By taking wheel hub as an example, pressure process is generally divided into 4
Step：
A) the liquid stage is risen：Aluminium liquid rises to stalk top from original position, and speed is slowly steady beneficial to flowing, speed one
As control in 16-18Mbar/S.
B) the type stage is filled：, from stalk top to mould an actor's rendering of an operatic tune top, speed general control is in 6-10Mbar/S. for aluminium liquid

D) packing stage：The maximum pressure being pressurized is setting value, according to attention the time required to product setting：Low pressure keeps
Stove highest bears pressure for 2000 millibars, when more than this value, equipment alarm and releasing pressure automatically；
1. liter liquid stage：The height (900mm) of stalk, the total height (380mm) in depletion face and stalk bottom are to protecting
The distance (80mm) of furnace bottom is held, then divided by 4mm/mbar=150, it is considered to the reason such as resistance, 1.1 coefficients are taken, therefore rise the liquid stage
Pressure：150*1.1=165mbar；Time：Pressure is equal to divided by the S of speed 165/16 (18)=10 (9)
2. the type stage is filled：Pressure：(removed to the total height of distance (adding) product of mould gate bottom on stalk top
With) 4mm/mbar, then the coefficient 1.2 (1.3) of (×) resistance factor can just draw pressure value.；Time：Pressure ÷ speed (6-
10)=time

Experience, comparatively, in the case where condition is met, the pressure is the bigger the better.
4. packing stage：This section of pressure can set the time according to the size of product and experience.Pressure value is exactly to be pressurized
The peak in stage.
How compensation pressure is set：Each workpiece is often made, the liquid level in holding furnace will decline, because of the theory that we calculate
When, designed when according to liquid level highest, therefore before pressurizeing must the height of first liquid level rise to theoretical calculation starting point；
Calculate (citing)：Holding furnace can be regarded as approximate cylinder by we, be 800KG to highest liquid level gross weight, can obtain every milli
The aluminium liquid weight of the height of rice：800KG ÷ 380MM ≈ 2.1KG/MM, it is assumed that product blank weight 10KG, a wheel hub liquid is often done in side
Face declines：The ≈ 4.76MM of 10KG ÷ 2.1, then need compensation pressure be：4.76MM÷4MM/mbar≈1.19mbar.
How basic pressure is calculated：If aluminium liquid not filled it up with when aluminium liquid is added, from the height H of highest liquid level, to make
Liquid level can be risen to theoretical calculation starting point before pressurization, it is necessary to which add up a basic pressure in liter hydraulic coupling in advance；Calculate and (lift
Example)：Assuming that plus aluminium liquid thing liquid level 100mm is differed with a distance from highest, then the basic pressure that should be set is：100mm÷4mm/mbar
≈ 25mbar, basic pressure is if filling it up with：0.
How often bag casting number is set：After often bag casting number is provided with, then equipment can be automatically reminded to need to add aluminium
Liquid.Calculate (citing)：Because furnace bottom has the aluminium slag and impurity of many, therefore aluminium liquid can be crossed bottom by step, in case impurity enters producing
Product cause defective products.Stalk is 80mm with a distance from furnace bottom, typically should not just be used in below furnace bottom 150mm, therefore can use
The weight of efflux (it is that cylinder is calculated to regard furnace chamber) calculating：800KG-150mm × 2.1KG/MM=485KG, it is assumed that product
Weight be 10KG, then can do the quantity of product per alclad liquid is：485 ÷, 10 ≈ 48.
Use the automatic business processing and air inflow and furnace pressure that smelting temperature on the one hand can be realized with upper type
Automatically control, while also greatly improving the oxygen of the security, stability and raw material of whole antigravity digitlization casting system
Change degree, while whole antigravity digitlization casting system all realizes automation for the control after charging and the mode of discharging
Control, it is only necessary to artificial to be preset to raw material and casting requirement, can directly be automatically performed melting, the temperature to raw material
The regulation of degree, pressure and discharge method and load, greatly improve automation integrated level and production security and
The applicability of product.
