Abstract
The utility model relates to a metal melt bidirectional rotary magnetic field stirring purifier. The utility model comprises a metal melt container of which the upper part and the lower part are respectively provided with an inlet and an outlet, and is characterized in that the upper part and the lower part of the periphery of the metal melt container are respectively provided with a rotary magnetic field generator. The utility model can realize stirring, separating and purifying via operating the magnetic field's rotating direction of the two rotary magnetic field generators, quickly reaches the effect of purifying the metal melt and is suitable for purifying various metal melt.
Description
Technical field
The utility model relates to a kind of metal melt refining plant, and the two-way rotatingfield of particularly a kind of metal melt stirs refining plant.
Background technology
In the prior art, many metal melts need purifying treatment, remove inclusion, in the refining process as magnalium and alloy melt thereof, the flux-refining link that is absolutely necessary, conventional method is that flux is covered in the metal melt surface, adopting in metal melt blows stirs or churned mechanically mode, allow metal melt contact, utilize the sorption of flux, remove the inclusion in the melt inclusion with flux.Above-mentioned alr mode is difficult to guarantee that flux fully contacts with metal melt, therefore has only come-up to the inclusion at top to be removed, and after adding alloying element, these two kinds of alr modes also are difficult to guarantee the homogeneity of metal ingredient.
The utility model content
The purpose of this utility model is to provide the two-way rotatingfield of a kind of metal melt to stir refining plant, metal melt is contacted with liquid flux, fully stir melt simultaneously, make bath composition and temperature even, simultaneously can make flux and the inclusion fast hierarchical that is suspended in the metal melt again, reach the effect of refining molten metal.
For achieving the above object, the utility model adopts following technical proposals:
The two-way rotatingfield of a kind of metal melt stirs refining plant, comprises that top and the bottom are equipped with the metal melt container of import and export respectively, it is characterized in that the peripheral upper and lower of metal melt container is respectively arranged with a rotating magnetic field generator.
Two above-mentioned rotating magnetic field generators that rotating magnetic field generator is the controlling magnetic field sense of rotation.
Above-mentioned metal melt container is the stainless steel cylinder of a upward opening, and inwall is with refractory masses.
The utility model compared with prior art, have following conspicuous characteristics and advantage: the peripheral top and the bottom of the metal melt container in the utility model respectively are provided with a rotating magnetic field generator, the rotatingfield direction that both produce is opposite, can operate two magnetic field generators periodically changes sense of rotation simultaneously and keeps two rotatingfield directions opposite, then the metal melt in the container and interior inclusion thereof and the flux liquid of adding are fully stirred, operate two magnetic field generators then, make its magnetic field sense of rotation identical, utilize the difference of rotary centrifugal force and metal melt is separated with flux liquid with inclusion, refining molten metal.The utility model is simple in structure, can fully stir melt and make flux liquid and inclusion fast hierarchical in the metal melt, reaches the effect of refining molten metal, is applicable to the purifying treatment of various metal melts.
Description of drawings
Fig. 1 is the structural representation (state graph during stirring) of an embodiment of the utility model.
State graph when Fig. 2 is Fig. 1 example isolation of purified.
Embodiment
Preferred embodiment of the utility model is: referring to Fig. 1 and Fig. 2, the two-way rotatingfield of this metal melt stirs refining plant, comprising that top and the bottom are equipped with respectively imports and exports 2,8 metal melt container 1, and the peripheral upper and lower of metal melt container 1 is respectively arranged with a rotating magnetic field generator 10,9.Two rotating magnetic field generators 10,9 are the rotating magnetic field generator of controlling magnetic field sense of rotation.Metal melt container 1 is the stainless steel cylinder 4 of a upward opening, and inwall is with refractory masses 5.
Working process of the present utility model is as follows: at first open rotating magnetic field generator 10,9, make both rotatingfield directions opposite, keep the sense of rotation in this relativeness periodic variation rotating magnetic field generator 10,9, flux drop 7 is fully contacted with metal melt 3, make the non-metallic inclusion 6 in the flux drop 7 abundant absorption metal melts 3, fully stir metal melt 3 simultaneously, make its temperature and composition even.The rotatingfield direction of adjusting rotating magnetic field generator 10,9 then keeps in the same way, make center or the periphery migration of the flux drop 7 that is adsorbed with non-metallic inclusion 6 in the metal melt 3 and remaining flux drop 7 and non-metallic inclusion 6, reach the purpose of refining molten metal 3 to metal pool.
Principle of work of the present utility model is as follows: referring to Fig. 1, after metal melt 3 flows into container 1, make two rotating magnetic field generators 10 up and down, 9 rotatingfield direction is opposite, this moment metal melt 3 about two portions will make subtend and move, while is conversion rotating magnetic field generator 10 periodically, the sense of rotation in 9 magnetic fields, but remain magnetic field generator 10 up and down, 9 rotatingfield directions are opposite, then metal melt 3 will produce the intensive stirring action, make the flux 7 at top enter into metal melt 3, metal melt 3 is cleaned absorption non-metallic inclusion 6 wherein.Referring to Fig. 2, after stirring metal melt 3 reaches the some time, adjusting up and down, the rotatingfield direction of two magnetic field generators 10,9 is consistent, then the metal melt in the metal vessel 3 will be towards folk prescription to rotation, flux drop 7 and the inclusion 6 that adsorb by inclusion 6 in the metal melt 3 this moment will produce motion under action of centrifugal force, than the light inclusiones 6 of metal melt 3 to the migration of metal melt container 1 center, than the inclusion 6 of Metal Melting body weight to the 1 periphery migration of metal melt container.In addition, in the process of periphery or center migration, the increase of inclusion 6 and flux drop 7 concentration also will cause flux drop 7 to merge and inclusion 6 collisions are grown up, thereby improve the travelling speed of inclusion 6 or flux drop 7 greatly, thereby flux drop 7 and inclusion 6 in can sharp separation tramp m. melt 3 reach the purpose of refining molten metal.
