Description
Technical field
The utility model is related to semi-solid metal slurrg preparing technical field, is specially that one kind is used for metal semi-solid slurrying
Permanent magnetism agitating apparatus.
Background technology
The performance of metal material is heavily dependent in its tissue signature, material preparation process to tissue morphology control
It is that primary phase is grown in dendrite mode, when solid rate reaches 20% or so during putting forward high performance important means, conventional cast
When, then continuous dendrite grid structure is formed, alloy is lost macroscopical mobility, and cause cast properties to decline.20 generation
Record the semi-solid casting technology grown up at the beginning of the 70's, conventional cast mode is there occurs profound change, using semi-solid casting
The product that forming technique is produced is made, because pouring temperature is in solid-liquid two-phase region, subtracts casting amount of contraction in process of setting
Few, casting dimension accuracy is improved, and formability is good, suitable for production Complex Parts, it is possible to reach near net-shaped production, and organizationally
Eliminate column crystal and thick dendrite, make cast structure fine and closely woven uniform, defect and gross segregation are significantly reduced, in addition to type
The reduction of chamber thermal shock, accordingly improves die-casting die and the service life of injection chamber, improves yield rate and the performance of product.Half
Solid cast forming technique combines the advantage of liquid cast shaping and excellent suitability for press forming, and the performance of portioned product can be close to even
The performance of forging product is reached, is one of current most promising rapid metallic prototyping technique.

Low advantage；But exist one of the semisolid slurry permanent magnetism agitating apparatus being currently known has the disadvantage slurry can not be made uniformly to mix
Close, this shortcoming greatly reduces its practicality.
The patent No.：201410378936.8 a kind of semi-solid alloy solution permanent magnetic stirring that can be used for experiment is disclosed to fill
Put, be assembled by several permanent magnets and servomotor and control system, rotating cylinder is done simultaneously using the soft magnetic materials of high permeability
With reference to eight grades to inside enclosed gradual change system, the fixed steel construction of design, it is ensured that air gap is smaller, and adds temperature measurement system.
Rotating excitation field be by motor drive permanent magnet produce rotating excitation field so that semi-solid alloy solution produce induced-current so that
Alloy solution rotates；It uses the method that the heart adds center heating rod in the melt, melts core, in making up
The deficiency of heart mixing power, to expect to reach the purpose stirred；But this method is unworkable, because the method can not still be avoided
Heavier solid granulates are assembled by the effect of rotary centrifugal force to the inwall of container in slurry, so that the slurry mixing of generation is not
Uniformly.
The patent No.：201320722729.0 the equipment that low overheat permanent magnetic stirring prepares semi-solid metal slurry is disclosed,
Including protective cover and the elevating mechanism being located in protective cover, Stirring mechanism, cooling body and controlling organization, described liter
Descending mechanism, Stirring mechanism and cooling body are controlled by described controlling organization；Described Stirring mechanism includes
Stirring container, motor, turntable and permanent-magnet steel, described cooling body include cooling jacket and for measuring metal bath
The temperature sensor of temperature, described temperature sensor is connected with described controlling organization.The method at all can not using process
Solid granulates heavier in slurry are avoided to be assembled by the effect of rotary centrifugal force to the inwall of container, so that the slurry of generation is mixed
Close uneven, have a strong impact on its practicality.
