Description
Technical field
The present invention relates to it is a kind of inhibit ZCuSn10P1 alloy tin element segregation continuously prepare semi solid slurry device and
Method belongs to material science and technology field.
Background technique
The research of semisolid metal processing technology (semi-solid metal forming processes, abbreviation SSM)
Originate in the early 1970s, its principle be metal freezing temperature range by change primary phase forming core growth process,
Including being vigorously stirred, being added grain refiner, quickly solidification etc., to obtain the liquid-solid mixed of certain nearly spherical primary phase particle
Slurry is closed, this semi solid slurry temperature is lower than liquid metal, but has good mobility, is conducive to carry out further
It shapes.
Semi-Solid Metals Forming method includes rheological molding and two kinds of thixotropic forming.The pulping process of rheological molding is:
In cooling procedure, strong stirring or other processing are carried out to metal bath, obtaining has partially solidified semi solid slurry, and
Make the nascent solid phase in slurry in subsphaeroidal particle；Then directly resulting semi-solid-state metal slurries are formed, as die casting,
It squeezes or rolls, normally referred to as rheological molding technique.Thixotropic forming is that molten metal is cooled to solid phase from liquid phase, cooled
Strong stirring or other processing are carried out in journey, obtaining has partially solidified semi solid slurry, and the primary phase in slurry is in close
Spherical shape, it is further cooling to obtain the ingot with non-dendritic structure structure.Then, by obtained blank formation of parts as needed
Quality be split, then again by every piece of ingot be heated to need partial remelting degree, cast, forged, being rolled or
Extrusion molding, to produce the part with non-dendritic structure structure.
Semi-solid Metal Thixoforming is compared with liquid metal forming technology, comprising: it is steady to fill type, no turbulent flow and splash, thus
The defects of cast-internal dense structure, internal porosity, segregation, is few；Product tissue has non-dendrite structure, while dense structure, system
The high mechanical properties of product can be close to or up to the performance of press forging；Since metal stock is partially solidified, thus solidification shrinkage
Small, formation of parts dimensional accuracy is high, and surfacing is bright and clean, is able to achieve near-net forming, therefore the part machinery of semi-solid-state shaping adds
Work amount is small, can accomplish less or without machining；Forming temperature is low, and when semi-solid alloy shapes, it is latent to have released partially crystallizable
Heat, thus the thermal shock to mold is alleviated, increase substantially die life；Setting time shortens, and can be shortened the life of product
The period is produced, is conducive to improve production efficiency.
Due to having the above advantages, each scholar has carried out extensive research to semisolid metal processing technology in recent years, at present
The method for preparing semi solid slurry mainly includes mechanical mixing method, electromagnetic stirring method, near liquidus temperature method, strain-induced fusing
Activation method, spray deposition, hang plate cooling method etc..But there are still some disadvantages, such as thixotroping for semisolid metal processing technology
Shape the disadvantages of there are high production cost, production cycle length, nonuniform organization, oxidizable process；Although rheological molding is raw
Cost is relatively low for production, but the preservation conveying difficulty of slurries is big, and temperature is difficult to control.
Hang plate cooling method principle be when be in the above certain temperature of liquidus curve liquid metal contacts hang plate when, due to
It is subcooled and quick and a large amount of forming cores, and since the percussion during trickling makes intercrystalline mutually collide, rub, ultimately forms
Tiny, uniform spherical proeutectic tissue.This method equipment is simple, easy to operate, occupied area is small, save the cost and can be used for
The preparation of refractory metal semi solid slurry.
Tin bronze becomes because of the advantages that intensity is high, elasticity modulus is big, coefficient of friction is low, wear resistance and corrosion resistance is good after Kufil
The preferred material of high-speed rail contact line after gold.High tin content casting copper-tin alloy high rigidity characteristic is able to satisfy heavy duty, high speed and high temperature
And by strong friction working condition requirement, it is widely used in bushing, axle sleeve, bearing block, gear, the worm gear of the industries such as high-speed rail, ship, aviation
Deng.By taking China railways as an example, to reach 120,000 kilometers to the year two thousand twenty operating mileage, electrization rate will reach 60%, copper-tin alloy city
Field demand is huge.
But copper-tin alloy is referred to as one of solidifying segregation alloy the most typical, segregation comes across containing 4.7- extensively
In the series alloy continuous casting billet of 15% tin, the solidified structure of ingot casting.Alloy Theil indices are higher, and segregation tendency is bigger.Segregation can also be to
Casting billet surface migrates (inverse segregation) and forms " tin exudation ".Documents and materials show the cooling with gypsum mould, shell mould, sand mold, metal mold
Speed is sequentially increased, and the inverse segregation degree of casting sample successively becomes serious, it is seen that the control of tin segregation is to restrict copper and tin to close
An important factor for gold application.
Since primary phase is equiax crystal in tissue obtained by semi-solid casting, the presence of trident crystal boundary has obstructed tin element
Diffusion admittance has certain inhibiting effect to tin element segregation, therefore can be to a certain degree using the method for semi-solid processing
Upper inhibition tin element segregation, makes tin element content in primary phase reach 5 ~ 7%, in order to further be controlled tin element segregation,
The present invention carries out inhibiting tin segregation processing for the pulp stage in Foundry Production, and it is cold to carry out stage control to main process of setting
But.
Summary of the invention
For the above-mentioned problems of the prior art and deficiency, the present invention provides a kind of inhibition ZCuSn10P1 alloy tin member
The device and method for continuously preparing semi solid slurry of element segregation.The present invention is controlled by the first stage and is cooled down: liquid
ZCuSn10P1 alloy promotes molten metal moment to generate uniformly by hang plate cooling duct, using the chilling action of hang plate
Big supercooling, bulk temperature rapidly enter solid-liquid temperature range, and while promoting melt quick forming core, tin atom is retained in primary phase
Inside obtains the alloy pulp of the spherical primary phase comprising certain volume score；Second-order class constant temperature process, it is fast using primary phase
Fast forming core grow up the area Gao Fuxi around the equiax crystal to be formed, tin atom the copper-tin alloys peritectic reaction such as quick diffusion heating power
Characteristic is learned, is grown up the latent heat of generation in conjunction with primary phase forming core, metatectic transformation dynamic conditions is created, further promotes tin former
Son is to spreading inside primary phase, to reduce the Theil indices in liquid phase as far as possible, obtains few intercrystalline segregation and temperature is in solid-liquid section
Metal bath；The shaft-like solid phase such as interconnected is obtained in class constant temperature process, most of raffinate is mutually located at the three of equiax crystal
Boundary is pitched, so that the intergranular migrating channels of low melting point liquid phase are truncated or become complicated, effectively contains the generation of inverse segregation process, is
Post forming process effectively prevents the formation of inverse segregation (tin exudation) from creating conditions.The invention is realized by the following technical scheme.
