Background technology
Semi-solid forming technology, abbreviation SSM was the M.C.Flemings by Massachusetts Institute Technology 70 years 20th century
What in generation, proposed.The technology is in process of setting, and it is stirred vigorously, changes its forming core growth process, obtains a kind of gold
Belong to the solid-liquid mixed slurry that certain solid phase is carried in melt.It is low due to forming temperature, and resistance of deformation is small, the spy such as steady that fills type
Point, in automobile, the field such as aviation has a extensive future.
The preparation of semi solid slurry is the key of semi-solid-state shaping, and its preparation method mainly has two kinds：One kind is in external force
Or formed dendrite is crushed in the presence of outfield, mainly including mechanical mixing method, electromagnetic stirring method, Isothermal treatment method,
Hang plate cooling method, ultrasonic vibration method etc.；Second is that control process of setting carrys out dendrite inhibition shaping, mainly there is additive method.
Both of which has its advantage and disadvantage, and some is applied in actual production.Up to the present, semi-solid-state metal
Forming technique is generally used in aluminium alloy and magnesium alloy.
Hang plate is to be used within 1996 manufacture aluminium alloy and magnesium alloy semisolid slurry by Japanese UBE companies utility model
New technology.Forming process is：The alloy melt that will be above a certain temperature of aluminium alloy phase line is cast in graphite or steel alloy is made
Hang plate on, by the chilling action of hang plate, the quick forming core of alloy melt is grown up, and the process trickled on hang plate
In, melt internal grain constantly rubs, collides and finally gives uniform, tiny spheroidal structure.
The oxidative phenomena of metal bath is extremely serious when conventional bevel plate prepares semi solid slurry, shows to improve this
As the utility model uses thin seam hang plate, and metal bath empties channel interior air when flowing through thin seam passage, makes metal
Melt flow through hang plate it is thin seam passage during hardly with air contact, can preferably prevent molten metal oxidization.And tilt
Two are connected with cooling water above and below plate, it is ensured that thin seam passage contacts the lower temperature needed for surface is kept with metal bath, it is to avoid logical
Road internal surface temperature is persistently raised.The thin seam each surface in passage upper and lower, left and right has shearing and chilling action to metal bath,
Enhance treatment effect of the hang plate to metal bath.
The content of the invention

Length）, the width of passage is 100-200mm, is highly 5-10mm, and angle is 10 ° -70 °（Have below hang plate two can more than
The support of lower regulation, the size of angle is adjusted by the height of adjusting bracket）.
The use process of device described in the utility model：Alloy is placed in melting in smelting apparatus metal bath is made, made
Metal bath, is then cast on hang plate, melt by metal bath temperature 10 DEG C of -50 DEG C of insulation 30min more than liquidus curve
Flowed into along hang plate and hold blank device, obtain semi solid slurry.
Principle of the present utility model is：Metal bath is flowed through into an inside for thin seam passage and with temperature-controlled cooling device
Hang plate, metal bath passes through the chilling action of hang plate, the quick forming core of crystal grain in metal bath, and due to the mistake in trickling
Constantly mutually shearing, collision, friction between metal bath internal grain, finally gives tiny, uniform spheroidal structure in journey.Thin seam
Channel interior narrow space, metal bath flow through it is thin seam passage when by passage air all empty, metal bath hardly with
Air contact, preferably prevents molten metal oxidization.Two are connected with cooling water above and below hang plate, can be to thin seam passage surface
Temperature is controlled, and is prevented in casting process, and thin seam passage surface is persistently overheating, it is ensured that the thin seam passage in casting process
Surface is to the lasting chilling action of metal bath, and the thin seam each surface in passage upper and lower, left and right is to flowing through the metal of thin seam passage
Melt has shearing, chilling action, enhances treatment effect of the hang plate to metal bath, in continuous casting process constantly
Acquisition even tissue, tiny semi solid slurry.
The utility model patent compared with prior art, this have the advantage that：
（1）Device described in the utility model is simple to operate, cost is low, flow is short, can be connected with follow-up former,
Directly process casting；Temperature control is carried out to hang plate by the cooling water of hang plate top and the bottom, prevents hang plate in casting process
It is persistently overheating, it is ensured that lasting chilling action of the hang plate to metal bath.
（2）In use, the thin seam each surface in passage upper and lower, left and right is to flowing through thin seam for device described in the utility model
The metal bath of passage has shearing, chilling action, enhances treatment effect of the hang plate to metal bath；Thin seam channel space
It is narrow and small, metal bath flow through it is thin seam passage when by passage air all empty so that metal bath not with contacting external air,
It is effectively prevented the oxidation of the metal bath in casting process.
