Description
The present invention is a kind of multifunctional assembled liquid metal electric magnetic stirrer that is used for metallurgical industry and casting industry.
At present be used for the magnetic stirrer that liquid metal stirs three kinds of forms are arranged usually: a kind of rotating excitation field agitator that is based on the common asynchronous moter principle at metallurgical industry and casting industry; A kind of traveling-wave magnetic stirrer that is based on the linear electric motors principle; Also having a kind of is the magnetic stirrer that produces helical magnetic field.Present rotating excitation field and travelling-magnetic-field magnetic stirrer comparative maturity all on structure and technology, and on Metal Melting and continuous casting of molten steel, be applied.The helical magnetic field magnetic stirrer is at present also in development, two kinds of helical magnetic field magnetic stirrers in European patent 0005676 and 0014636, have been announced, its structure essential characteristic is, be combined into magnetic circuit by annular iron core and strip iron core, be packed with two cover windings independent of each other, wherein a cover excites rotating excitation field, the another set of travelling-magnetic-field that excites, both become helical magnetic field by superposition in round cavity, and two cover windings are fed by two power supplys respectively.The weak point of above-mentioned helical magnetic field magnetic stirrer is that they all are assembled into an integral body, is difficult to adapt to the requirement that casting blank section changes in the continuous casting; In addition, structure is complicated, safeguards also inconvenience, the particularly replacing of winding, and need two cover power supplys, thereby be subjected to certain limitation on using.
The object of the present invention is to provide a kind of highly versatile, applied widely, be convenient to keep in repair, assemble and be suitable for the magnetic stirrer of producing in serial form.
Magnetic stirrer involved in the present invention adopts different methods of attachment to form by the polylith planar inductor, planar inductor adopts the independently magnetic pole elements of being made up of T shape iron core and O shape winding to form, the number of the selected magnetic pole elements of difference that can be according to actual needs, and the connected mode between each magnetic pole elements, through the conversion of connected mode, can encourage the magnetic field of rotation, row ripple, three kinds of forms of spiral respectively.And can be mounted to multiple shape according to the difference of casting blank shape, as U-shaped, quadrangle, triangle, polygon.Below in conjunction with accompanying drawing 1,2,3, just content of the present invention is introduced in detail.
Fig. 1 is the sectional side elevation of magnetic stirrer.
Fig. 2 is the cross-sectional figure of magnetic stirrer shown in Figure 1.
Fig. 3 is the iron core and the magnetic pole elements iron core schematic diagram of planar inductor.

Magnetic pole elements (22) is made up of a T shape iron core (25) and an O shape winding (17). The number that forms magnetic pole elements (22) on planar inductor (15) quantity of this agitator and the every planar inductor should guarantee to excite the magnetic field of required form according to Power Supplies Condition. For example adopt three phase mains usually to use three planar inductors, three magnetic pole elements of every planar inductor configuration; Two-phase power supply is used four planar inductors usually, four magnetic pole elements of configuration on the every inductor. The T shape iron core (25) of several magnetic pole elements (22) of inductor (15) is pieced together groove by edge and is linked into an integrated entity, (seeing accompanying drawing 3), or several T shape iron cores are made an integral body, foundary weight plate (19) at its two side bonds ordinary carbon steel, two ends are pieced together groove with non-magnetic stainless steel end plate (21) by edge and are connected with T shape iron core (25), and with foundary weight plate (19) welding, make the planar inductor iron core that is formed by T shape iron core become as a whole. Use not magnetic stainless steel end plate, the one, in order to reduce the end magnet short-cut path, strengthen the air-gap field of top, end; The 2nd, clamp T shape iron core that edge is combined into and fixing two ends winding; The 3rd, be convenient to install; Adopt foundary weight plate and end plate welding procedure, saved the securing members such as screw rod, packaging technology is simplified, and can be reduced the eddy current loss of using bolt to cause. Planar inductor (15) is equipped with not magnetic stainless steel shell (10), and the framework (30) that is connected and fixed usefulness is housed on the base plate (9), and (31) are fixedly to use slot wedge.
The agitator circuit connecting mode that is used for three kinds of form magnetic fields of excitation is:
A, excite the winding connection method of rotating excitation field: with the terminals of all windings (17) on the same inductor (15) end to end respectively and connect or end to end order compose in series a phase winding, adjacent phase winding adopts not cophase supply, as when adopting three-phase alternating-current supply, adjacent inductor power phase difference is 120 degree, as adjacent inductor power phase difference is 90 degree when adopting the two-phase alternating current source, constitutes rotating excitation field.
B, excite the winding connection method of travelling-magnetic-field: be on each planar inductor (15) on the same position all windings (17) end to end respectively and connect or order serial connection end to end, form a phase winding, adopt not cophase supply between adjacent phase winding.As when adopting three phase mains, phase difference is 120 degree between every phase winding; As when adopting two-phase power supply, phase difference is 90 degree between each winding.
C, excite the winding connection method of helical magnetic field: with the winding (17) on each planar inductor (15), along hand of helix end to end and connect or end to end order compose in series a phase winding, adjacent winding adopts not cophase supply.As when adopting three-phase electricity, phase difference is 120 degree between every phase winding; When adopting the two-phase electricity, phase difference is 90 degree between every phase winding.
The present invention compared with prior art advantage is: magnetic stirrer is made up of the planar inductor that discrete magnetic pole elements edge is combined into, each planar inductor is independently of one another, therefore can and assemble according to size, the shape of strand, reach low in energy consumption, efficient is high and it is easy to maintenance to use the requirement of blank stirring extent.This body structure of planar inductor manufacturing process is simple, and is applied widely, is easy to producing in serial form.Same agitator can excite the magnetic field of three kinds of forms respectively under the situation of any parameter of not conversion.And can connect according to the difference of using the field power supply supply mode.
