Description
Technical field
The present invention relates to aluminum alloy smelting technical fields, are in particular a kind of swell type permanent magnetism agitating apparatus.
Background technology
Aluminium alloy is common lightweight metal material, it is widely used in the industry such as automobile, ship, space flight, machinery, communication
In, it has the characteristics that good processing performance, light weight, energy saving.Existing cast aluminium alloy gold due to needing to add a variety of rare earths
Element, the diffusivity of various elements during the addition process without, it is therefore desirable to mixed with permanent magnetic stirring, it is mixed in order to be promoted
Efficiency is closed, needs to develop a kind of device that can accelerate element mixing, obtains high-performance, homogeneous aluminum alloy materials.
Invention content
The invention mainly solves the technical problem of providing it is a kind of can accelerate element mixing device, obtain high-performance,
Homogeneous aluminum alloy materials.
Swell type permanent magnetism agitating apparatus proposed by the present invention, including smelting furnace, permanent magnetic stirring magnet and permanent magnetism partition board, permanent magnetism
Partition board is located at close to melting furnace bottom above permanent magnetic stirring magnet, and the direction of magnetization of permanent magnetism partition board is perpendicular to the flat of permanent magnetism partition board
Face, the area of permanent magnetism partition board are less than the area of the bottom of smelting furnace, and the magnetic field intensity of permanent magnetism partition board is less than permanent magnetic stirring magnet
Magnetic field intensity.
Preferably, in sector, fan-shaped central angle is 10 degree and arrives 180 degree above-mentioned permanent magnetism partition board.
Preferably, above-mentioned permanent magnetism partition board is square.
Preferably, above-mentioned permanent magnetism partition board assume diamond in shape, ellipse, triangle or irregular shape.
Preferably, above-mentioned permanent magnetism partition board is in uneven thickness, and the thickness of permanent magnetism separator edge is less than among permanent magnetism partition board
Thickness.
Preferably, the material of above-mentioned permanent magnetism partition board is Nd-Fe-B permanent magnet, and the material magnetic field intensity of permanent magnetism partition board is forever
Magnetic stirs ten five five to percent the percent of the magnetic field intensity of magnet.
The present invention swell type permanent magnetism agitating apparatus operation principle and have the beneficial effect that：
Permanent magnetism partition part fills the space between smelting furnace and permanent magnetic stirring magnet, provides a non-homogeneous magnetic spatially
Field and temporal pulsed magnetic field cause molten metal by this non-uniform magnetic-field spatially and temporal pulsed magnetic field
Internal portion is formed the effect of surge by a non-uniform driving force, for spatially, detailed process be it is such, with
Permanent magnetism partition board is in for fan-shaped, it is assumed that when original state the South Pole of permanent magnetism partition board downward, the arctic upward, permanent magnetic stirring at this time
The South Pole rotation of magnet comes, since the magnetic field intensity of permanent magnetic stirring magnet is more than the magnetic field intensity of permanent magnetism partition board, permanent magnetism partition board
Be magnetized, become the arctic downward, the South Pole upward, due to obtaining the reinforcement in permanent magnetism partition board magnetic field, the metal right over permanent magnetism partition board
Liquid is under the field drives of a bigger, and the metal fluid rotated at this time is in the position of permanent magnetism partition board（Permanent magnetic stirring magnet
The South Pole be located just at the underface of permanent magnetism partition board at this time）, the position of the arctic relative to permanent magnetic stirring magnet, by bigger
Field drives, this uneven driving may result in the deformation and compression of metal fluid, formed significantly on metal fluid surface
It surges, in addition, for from the time, during in the South Pole of permanent magnetic stirring magnet, rotation comes, the original pole of permanent magnetism partition board
Property be the South Pole downward, upward, and the rotation polarity in South Pole of permanent magnetic stirring magnet that comes is on the contrary, be rotated for the arctic
Before the South Pole magnetization of permanent magnetic stirring magnet, the magnetic field that the metal liquid above permanent magnetism partition board is experienced is less than permanent magnetic stirring magnet
The South Pole itself magnetic field intensity, after magnetization, moment in the magnetic field that the metal liquid above permanent magnetism partition board can be experienced increases
Greatly, that is, pulsed magnetic field, the appearance of pulsed magnetic field so that the metal liquid above permanent magnetism partition board is by moment increased drive
It is dynamic, lead to the deformation and compression of metal fluid, is formed on metal fluid surface and significantly surged.When the South Pole of permanent magnetic stirring magnet
After being rotated away from, the polarity of permanent magnetism partition board be the arctic downward, upward, when the arctic of permanent magnetic stirring magnet, rotation comes in the South Pole
In the process, and above-mentioned process can be repeated, generation non-uniform magnetic-field spatially generates pulsed magnetic field in time.Permanent magnetism
Partition board it is in uneven thickness, the thickness of permanent magnetism separator edge is less than the thickness among permanent magnetism partition board, this is stirred to reduce permanent magnetism
The impact for mixing the driving device discontinuity of magnet, due in the magnetic pole and permanent magnetic stirring magnet approach process of permanent magnetism partition board
Magnetic pole is on the contrary, permanent magnetic stirring magnet by a repulsive force, can cause the driving current of driving device a steep increasing occur, in this way
The load of transmission system, driving circuit and control system can be increased moment, and when the magnetic polarity reversal and and permanent magnetism of permanent magnetism partition board
When the magnetic pole of stirring magnet is consistent, the repulsive force pop-off that permanent magnetic stirring magnet is subject to can reduce transmission moment in this way
The load of system, driving circuit and control system increases the variation dropped suddenly to transmission system, driving electricity suddenly in order to reduce this moment
The impact on road and control system, the thickness of permanent magnetism separator edge are less than the thickness among permanent magnetism partition board, allow permanent magnetism separator edge
Magnetic field intensity is less than the magnetic field intensity among permanent magnetism partition board, allow the repulsive force that permanent magnetic stirring magnet experiences present one by it is small to
Big progressive formation provides a gradual change buffering for transmission system deformation, driving circuit adjustment and control system adjustment, and then drops
Low-loss extends guarantee maintenance interval time, permanent magnetism partition board assumes diamond in shape, ellipse, triangle or irregular shape be also for
This reason.By taking permanent magnetism partition board assumes diamond in shape as an example, the area of the permanent magnetism partition board of diamond tips is small, the permanent magnetism partition board of corresponding position
Magnetic field is small, therefore an ascending progressive formation is presented in the repulsive force that permanent magnetic stirring magnet can be allowed to experience, and equally reaches
To identical effect.
