Description
Technical field
The invention belongs to the metal semi-solid slurry preparing technical field, be specifically related to a kind of electromagnetic agitation and vibration set composite of ferrous metal semi-solid pulp preparation.
Background technology
Semi-solid metal forming is the novel forming technique of a kind of metal, and the advantage that it combines casting and forges only needs a small amount of operation just can be shaped than complicated shape and high performance workpiece.Compare with conventional cast, this technology has that forming temperature is low, die life significant prolongation, can improve the precision and the mechanical property of workpiece simultaneously.And compare with traditional forge hot, semi-solid state forming technique has that plastic force is low, good fluidity, can realize near-net-shape, especially only need a procedure can be shaped than the workpiece of complicated shape.Up to the present, in low melting point non-ferrous metal metal field, this technology has obtained to use widely, especially in industry such as automobile, Aero-Space, electrical equipment.But to the high-melting-point ferrous material, semi-solid-state shaping is also still in conceptual phase.
In the semi-solid-state shaping process, the semi solid slurry preparation is a very crucial technical step, the success or not of decision semi-solid-state shaping, and its purpose is for having obtained the tiny spherical or torulose microstructure of axle that waits of non-dendrite.Up to the present, people have developed the new technology and the new technology of many preparation metal semi-solid slurries, activate (SIMA method), heat treating process, interpolation powder alterant method etc. as electromagnetic stirring method, mechanical mixing method, vibratory drilling method, strain-induced fusing.But, successfully be applied to have only electromagnetic stirring method on the industrial production, and the preparation alloy be mainly non-ferrous metal, as aluminium alloy, magnesium alloy etc.Compare with non-ferrous metal, the research of ferrous material semi-solid state forming technique is less, reason mainly is ferrous metal fusing point height (1300-1500 ℃), doubles with the fusing point (500-700 ℃) of aluminium alloy, brings very big difficulty for ferrous metal semi-solid pulp preparation and semi-solid-state shaping.
Mechanical mixing method is that the metal semi-solid slurry preparation is used the earliest.This method utilizes rotating vane or the stirring rod nascent solid phase in will solidifying to smash, and obtains the semi solid slurry of spherical or nearly spherical nascent solid phase, and its advantage is that equipment is simple, be of value to and form tiny microstructure; But shortcoming is, ferrous metal melt temperature height during pulp preparation, is lacked, easily causes the burn into metal paste to be vulnerable to pollution etc. the service life of rotating vane or stirring rod, therefore prepares this method at metal semi-solid slurry and uses less.
The electromagnetic agitation ratio juris is to utilize rotary electromagnetic field to produce induction field in molten metal, and molten metal produces motion under the effect of Lorentz force, thereby realizes the purpose to the molten metal stirring.The outstanding advantage of this method is contactless paddling process, has effectively overcome the problem that is similar to churned mechanically blade or stirring rod corrosion contamination, has in addition that mixing parametric control is flexible, an easy adjusting etc.At present, in the preparation of non-ferrous metal semi solid slurry, electromagnetic stirring method is most widely used general, is applied on the industrial production.But to ferrous material, this method also is in initial stage, reason is, ferrous metal fusing point height, melt conductance are low, thereby bring very big difficulty to semi solid slurry preparation, power of agitator is big as required, mixing time long and heating, insulation, cooling procedure in need good measure etc.
The advantage of mechanical oscillation semi solid slurry preparation method is simple, the easy realization of equipment, small investment etc.In recent years, the Central China University of Science and Technology adopted low-frequency mechanical vibrations that A390, ZL 101 alloy etc. is carried out the semi solid slurry preparation, had obtained the more tiny non-dendritic structure that waits axle.But during vibration, thermocouple and the control assembly thereof of measuring temperature are subjected to violent exciting force, cause reducing their job stabilitys, the lost of life.
Control degree of superheat cast semi solid slurry preparation method is to prepare semi-solid metal slurry or blank by control alloy pouring temperature and solidification cooling, and this technical method does not generally adopt any stirring, so preparation technology is simple.Its shortcoming is that efficient is low, and structural homogenity is relatively poor, especially ferrous metal fusing point height, be difficult to temperature control, therefore lower, the difficult realization to this method side's efficient of ferrous metal.
Above-mentioned several preparation metal semi-solid slurries are effects separately, and its efficient is lower, power requirement is bigger, and preparation is difficult to obtain good effect to the ferrous material semi solid slurry.In recent years, had the scholar that low melting point non-ferrous metal semi solid slurry is combined above-mentioned both or many persons and obtained better effects, microstructure is tiny, uniformly spherical or closely spherical, preparation time is short, required power is little etc.
On the other hand, in the semi-solid rheological molding technology, quantitatively cast is a crucial step.Conventional method generally adopts the stopper rod formula, and its advantage is that structure is simpler, and when still pouring into a mould, semi solid slurry is by gravity or pressing mode discharging, instability of flow, so quantitative error is bigger, does not still also have good solution at present.
