    The invention relates to a method for casting a melt of a metallic material, and to a casting device designed to carry out the method.
    EP1097013B1 discloses an electromagnetic pump for conveying a melt between a melting furnace and a casting mold.
    The structure of EP1097013B1 has the disadvantage that the electromagnetic pump has poor effectiveness, particularly with paramagnetic materials such as aluminum.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide a method and a device by means of which paramagnetic materials can also be conveyed.
    This object is achieved by a method and a device according to the claims.
    According to the invention, a method for casting a melt of a metallic material is provided. It is provided here that the melt of the metallic material is acted on by means of a first electrode and a second electrode which contact the metallic material and at the same time a magnetic field acts on the area of the melt which is exposed to current.
    The method according to the invention has the surprising advantage that the effect of a magnetic force on the melt is increased when current is generated by means of the
    2.29
    N2018 / 10400 AT-00
    Electrodes is passed into the melt and thereby an electric field is generated in particular in the melt. This surprising result was particularly noticeable with aluminum. In particular, it is conceivable for the melt to be forced in a predeterminable direction by the action of the magnetic force in order to influence the flow of the melt. As a further surprising advantage, it has been shown that a melt which is subjected to a magnetic field or a current in this way forms a solid with an improved structure after it has solidified. With these measures, imperfections in the structure of the solid body can be reduced, whereby the strength of the solid body or the susceptibility to errors of the solid body can be reduced.
    Furthermore, it can be useful if the magnetic field is generated by an electromagnet. This has the advantage that the magnetic field can be selectively applied or removed again. In addition, the direction of action of the magnetic field can be influenced by means of an electromagnet.
    Alternatively, it can be provided that the magnetic field is generated by means of a permanent magnet. Such a permanent magnet can be designed, for example, in the form of a neodymium magnet.
    Furthermore, it can be provided that direct current is applied to the electromagnet.
    Alternatively, it can be provided that the electromagnet is supplied with alternating current.
    In addition, it can be provided that direct current is applied to the melt by means of the electrodes.
    Alternatively, it can be provided that the melt is acted upon by alternating current by means of the electrodes.
    In a special embodiment variant it can be provided that the electrodes and the electromagnet are acted upon by alternating current, the on
    3.29
    N2018 / 10400-AT-00 the alternating current applied to the electrodes and the alternating current applied to the electromagnet are phase-shifted with respect to one another or are actively phase-shiftable in such a way that a magnetic force acts on the melt in the desired direction.
    It can further be provided that the metallic material comprises aluminum or an aluminum alloy. Since aluminum is paramagnetic, a surprisingly good magnetic effect can be determined with this material in particular by applying additional current to the melt. As a result, the force effect of the magnetic field acting on the melt by means of the magnet can be increased.
    In addition, provision can be made for the melt to be transported in a flow connection element into a mold cavity, the magnetic field being designed such that a magnetic force acts on the melt in the region of the flow connection element. This measure allows a magnetic force to be influenced on the melt in the flow connection element, as a result of which the melt can be conveyed, for example, by means of the magnetic force or the conveying action can be supported by means of the magnetic force. Furthermore, it is also conceivable that the magnetic force is oriented in such a way that it brakes or counteracts the flow of the melt. The magnetic field can be used, for example, to stop or brake the flow of the melt, for example to reduce turbulence and air pockets in the melt.
    Alternatively or additionally, it can be provided that the magnetic field is designed in such a way that a magnetic force acts on the melt in the region of the gate. This measure allows a magnetic force to be impacted on the melt in the gate, whereby the melt can be conveyed for example by means of the magnetic force or the conveying effect can be supported by means of the magnetic force. Furthermore, it is also conceivable that the magnetic force is oriented in such a way that it brakes the flow of the melt or the
    4.29
    N2018 / 10400-AT-00 sem counteracts. The magnetic field can be used, for example, to stop or brake the flow of the melt, for example to reduce turbulence and air pockets in the melt.
    Also advantageous is a configuration according to which it can be provided that the magnetic force acts on the melt in the conveying direction in the flow connection element.
    According to the invention, a casting device is provided for casting a melt of a metallic material, the casting device having a flow connection element for guiding the melt. A first electrode and a second electrode are arranged on the flow connection element such that they can contact the melt. Furthermore, a magnetic element is arranged on the flow connection element, which is designed to apply a magnetic field to the area of the melt that is supplied with current.
    The casting device according to the invention has the advantage that it can improve the quality of the casting process.
    Furthermore, it can be expedient if the magnetic element is designed as an electromagnet which has a coil which surrounds the flow connection element at least in regions. In particular, a coil arranged around the flow connection element can apply a sufficient magnetic force to the melt.
    In addition, it can be provided that the flow connection element is designed as a closed tube. The tube can have a circular or a rectangular cross section.
    Furthermore, it can be provided that a plurality of mold cavities are formed in a casting mold, each of which is coupled to a casting run by means of a gate, a magnetic element being arranged in one or more of the gates. It is particularly advantageous if each of the gates has a magnetic element. As a result, the inflow of the melt to the individual mold cavities can be selectively accelerated or slowed down. Through this
    5.29
    N2018 / 10400 AT-00
    As a measure, it is possible for the individual mold cavities, which are different distances from a central casting run, to be filled uniformly and simultaneously with melt, so that the melt introduced into the individual mold cavities can solidify at the same time.
    According to a particular embodiment, it is possible for the flow connection element to have a rectangular cross section, the first electrode and the second electrode being arranged on two opposite sides of the cross section. Especially on flow connection elements with a rectangular cross section, the electrodes can be easily arranged on opposite surfaces or sides of the cross section.
    It can also be provided that the flow connection element opens into a gate on the underside of the mold cavity.
    It is also conceivable that the casting device is designed as a low-pressure casting device or as a counter-pressure casting device, the flow connection element being designed as a riser pipe. In particular, it is conceivable that the magnetic element is arranged in the area of a mold mounting plate. The platen is formed between the furnace and the mold.
    Alternatively, it can be provided that the casting device is designed as a continuous casting device, the magnetic element being arranged in the area of the mold or in the area of the casting tube.
    Furthermore, it can be provided that a plurality of mold cavities are formed in a casting mold, each of which is coupled to a casting run by means of a gate. It can be provided that a magnetic element is arranged in one or more of the gates.
    It can further be provided that the coil is designed in such a way that the flow cross section of the flow connection element is enclosed in a ring.
    6.29
    N2018 / 10400 AT-00
    Furthermore, it can be provided that the first electrode and the second electrode and the magnets are arranged relative to one another in such a way that the electrical flux generated by the electrodes is arranged at a right angle to the magnetic field.
    Furthermore, it can be provided that the electrodes are designed as copper electrodes.
    It can further be provided that the electrodes are formed from a carbon. This has the advantage that impurities are less and the resistance is also reduced.
    Furthermore, it can be provided that the electrodes are arranged diametrically opposite one another as viewed with respect to the flow cross section.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    The casting device 1 comprises a furnace 2 in which a receiving space 3 for receiving melt 4 is formed. In particular, it can be provided that
    8.29
    N2018 / 10400-AT-00 a crucible 5 is arranged in the furnace 2, in which the melt 4 is received. The crucible 5 can be formed from a ceramic material which has a high temperature resistance. The furnace 2 can be used in particular to keep the melt 4 at a high temperature level, so that it remains in the molten state.
    Furthermore, a platen 6 is formed, which limits the furnace 2 towards the top. The platen 6 can either be designed as a separate component or as an integral component of the furnace 2. A mold 7 is arranged above the platen 6 and has a lower mold part 8 and an upper mold part 9. The two mold parts 8, 9 form a mold cavity 10 which serves to receive the melt 4 and to shape the cast workpiece.
    The casting mold 7 can be designed, for example, in the form of a mold, which is suitable for casting several thousand workpieces.
    As an alternative to this, it is also conceivable for the casting mold 7 to be designed as a lost casting mold, such as from a sand material, and thus only for casting a single workpiece.
    Furthermore, a flow connection element 11 is formed, which is used to conduct the melt 4 from the crucible 5 into the mold cavity 10. In the present exemplary embodiment, the flow connection element 11 is designed as a riser pipe 12 which projects into the receiving space 3 of the furnace 2 and penetrates the mold mounting plate 6. The lower mold part 8 can connect directly to the riser pipe 12 and have a gate 13 into which the riser pipe 12 opens. In addition, a support structure 14 is shown in a highly simplified manner, which can be coupled to the upper mold part 9 and can be used to move the upper mold part 9 relative to the lower mold part 8.
    The furnace 2 also has a compressed air supply opening 15, through which compressed air can be introduced into the receiving space 3 of the furnace 2. By

    In a further embodiment variant it can also be provided that the electrodes 20, 21 are placed on the inner lateral surface 19 of the flow connection element 11 or the gate 13. In such an embodiment, the electrodes 20, 21 protrude inward relative to the inner surface 19 of the flow connection element 11 or the gate 13.
    Furthermore, a magnetic element 16 is formed, which in the present exemplary embodiment is arranged in the region of the flow connection element 11. In the present exemplary embodiment, the magnetic element 16 is designed as an electromagnet 17 which has a coil 18. The coil 18 is designed in such a way that the flow cross section of the flow connection element 11 is enclosed in a ring shape by the coil 18. In particular, as can be seen from FIG. 1, it can be provided here that the coil 18 is arranged inside the furnace 2 and surrounds the riser pipe 12. Alternatively, it can also be provided that the coil 18 is integrated in the riser pipe 12. Of course, a permanent magnet can also be provided instead of the coil 18.
    It can be seen from the sectional view II that a first electrode 20 and a second electrode 21 are arranged in the area of the magnetic element 16 on an inner circumferential surface 19 of the riser pipe 12, which electrodes are designed to carry the melt 4, which is transported in the riser pipe 12, with To apply electricity. A magnetic force 22 can be exerted on the melt 4 guided in the flow connection element 11 by means of the magnetic element 16. The magnetic force 22 can act in a conveying direction 23 or can also act counter to the conveying direction 23.
    10/29
    N2018 / 10400 AT-00
    In particular, it is conceivable that the magnetic force 22 acts as a support for conveying the melt 4 from the crucible 5 into the mold cavity 10.

    FIG. 6 shows a further embodiment of the casting device 1, which may be independent of its own, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 5. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 5.
    In this embodiment of FIG. 6, the casting device 1 is designed as a continuous casting plant. Here, the melt 4 is guided by means of the flow connection element 11, which in this case is designed as a pouring tube, into the casting mold 7, which is designed as a mold.

Furthermore, as an alternative or in addition, it is also conceivable that the magnetic element 16 and the electrodes 20, 21 are integrated in the flow connection element 11 or are arranged in the region of the flow connection element 11.

    N2018 / 10400 AT-00
    Flow cross section is applicable to each of the exemplary embodiments of pouring devices 1 described in FIGS. 1 to 6.
