Description
Technical fieldThe invention belongs to the metal material liquid state and shape technology, particularly the high-performance semisolid Accurate Shaping technology of each metalloid material.
Background technologyThe development of modern science and technology has proposed more and more higher requirement to all kinds of high-performance abnormity component performances, such as engine crankshaft, aircraft worm gear dish, roll etc.Semi-solid processing can make the grain refinement of metal material, obtains tiny, subsphaeroidal, non-dendritic structure, thereby greatly improves the mechanical property of workpiece.Modern Accurate Shaping technology can make surface of the work bright and clean, and appearance and size is accurate, thereby greatly reduces manufacturing cost.The present invention is to promoting the compound of multinomial advanced technology and use, particularly improve all kinds of high-performance abnormity components performance, cut down finished cost significant.
1. semi-solid processing
The semi-solid processing of metal material is the guardian technique in all kinds of high-performance member Accurate Shaping technology, it directly affects the quality of all kinds of high-performance abnormity component performances, " semi-solid metal slurry new preparation process and New Machining Technology " (Jiang Yunxi, thanks to aquatic, Li Xinggang work, " forging technology " 2003 28.6) in, disclose the at present development of semi-solid processing technology both at home and abroad, its main method is:
(1)
New MIT technique" new MIT technique " method be 2000 by Massachusetts Institute of Technology's propositions such as Flemings of (Massachusetts Institute of Technology is called for short MIT), Idraprince Co., Ltd obtains this technical patent.Its principle be alloy melt under liquidus temperature owing to stirring acting in conjunction with cooling, caused the cold forming core of mistake of alloy grain in the solution volume, rapid cooled alloy solution just can obtain comparatively ideal semi solid slurry, and then the injection die cavity is shaped again.
(2)
The cooling chute methodThe cooling chute ratio juris is: will be poured on a little more than the motlten metal of liquidus temperature on the cooling chute, because the cooling effect of skewed slot, there is tiny grain nucleation to grow up in chute wall, the impact of metal fluid and the Gravitative Loads of material make crystal grain come off and overturn from chute wall, to reach mixing effect.Metal paste by cooling chute falls into container, the control vessel temp, and namely Slow cooling is cooled to be incubated after certain semi-solid temperature, meets the requirements of solid volume fraction, can carry out rheological molding and thixotropic forming subsequently.
(3)
Double helix semi-solid state metal rheological injection molding methodThe operation principle of the method is that motlten metal is melting in crucible, reaches than liquidus temperature to exceed approximately 50 ℃ predetermined temperature, with motlten metal insulation 15 minutes, obtains uniform chemical composition.When motlten metal was magnesium alloy, crucible adopted argon shield.Molten metal enters the double helix shear with certain speed, adjusts its temperature, is subject to simultaneously the shear action of twin-screw, obtains the desirable semi solid slurry of certain solid phase percentage.
(4)
Shearing-cooling-rollingThe operation principle of the method is: the motlten metal that will be heated to uniform temperature injects the gathering sill of roll gap top through nozzle, leave certain gap between roll and the boot-shaped seat, and roller surface has certain roughness simultaneously, water flowing cooling in the roll.Because the cooling effect of roll and boot-shaped seat, aluminium alloy solidifies, the roll that rotates produces the shear agitation effect to the alloy of partial coagulation, make aluminium alloy be converted into semi solid slurry, and by the frictional force that roll applies semi solid slurry is hauled out from roll and boot-shaped seat gap, flow by the stripper guiding semi solid slurry that is installed in discharging opening.Can directly carry out rheological molding, also can be made into the semi-solid blank of required size, then carry out thixotropic forming.
(5)
NRC techniqueThe production process of NRC method is: 1. motlten metal is controlled in the above several years scope of liquidus temperature; 2. motlten metal is poured in the heat-insulated container, because the cooling effect of container produces a large amount of primary phase crystal grain in molten metal; 3. cover with pottery up and down at container, prevented cold; 4. utilize the air-cooled semi-solid temperature that metal is cooled to set; 5. adjust the temperature of slurry by the high frequency induction heater of heat-insulated container outside, adjust the solid volume fraction of metal paste, form spherical slurry, satisfy the shaping needs, this process need 3 to 5 minutes; 6. the heat-insulated container that overturns is poured semi solid slurry into sleeve.Simultaneously, the oxide layer of upper surface sinks to the sleeve bottom, can prevent that oxide layer from entering product; 7. slurry is directly poured in the die cavity, and be shaped.
(6)
The different liquids mixing methodThe different liquids mixing method is the motlten metal mixing with two or three hypoeutectic composition, or the motlten metal of hypoeutectic and hypereutectic composition is mixed, and the motlten metal that will mix all remains on more than the liquidus curve, does not have nucleus or nucleus in the motlten metal seldom.Mixing is to carry out in thermally insulated container, and perhaps mixing channel is wanted preheating by carrying out in the static mixing channel of the Coating graphite of thermally insulated container at one, and when guaranteeing that melt-flow is crossed mixing channel, its temperature remains on more than the liquidus temperature.Melt flows in the turbulent flow mode on mixing channel, makes its mixability good.The mixing of two kinds of melts causes spontaneous heat conduction (heat discharges), hypoeutectic absorbs hypereutectic heat, and the new alloy temperature that obtains after the mixing contains a large amount of nucleus about liquidus temperature, further heat treatment can form have tiny, the semi solid slurry of spheroidal structure.
(7)
The Near-liquidus Casting methodThe Near-liquidus Casting method mainly adopts the factors such as temperature, time of repose, casting speed and intensity of cooling of control casting, with melt temperature more than the liquidus temperature or close to liquidus temperature after insulation is left standstill, and under certain cooling rate, pour into a mould, thereby obtain tiny, subsphaeroidal, non-dendrite microstructure of semisolid.
The above new technology of introducing is the semi-solid rheological molding technology, present semi-solid processing technique can be divided into two kinds of semi-solid rheological molding and semi-solid die castings, their common feature is to make semi solid slurry first outside casting mold, implements rheology or thixotropic forming technique again.Rheological molding technique is will be first the direct casting of semi solid slurry of preparation be become strip blank, thixotropic forming technique be will preparation semi solid slurry be cast as billet after, post bake again, the technical process of thixotropic forming after the remelting.The subject matter of semi-solid rheological technology is to need a semisolid cooling and pulping process before cast at present, needs strict temperature control to establish and puts forth energy and certain pulping equipment, has therefore greatly improved the complexity of manufacturing cost and technique.
