摘要： The invention relates to an arrangement and a method for electrochemically storing energy in electrochemical cells with a large diameter and a high storage capacity. A preferred field of application of the invention is the use for stabilizing electric supply systems. The arrangement for storing electric energy in an electrochemical cell consists in layering a liquid metal that forms the cathode, a liquid electrolyte, and a liquid metal or semimetal that forms the anode. An electrically insulating inner tube is attached along the vertical axis of the arrangement, the presence of said inner tube preventing the occurrence of Rayleigh-Taylor instability or other instabilities in the liquids and thus the intermixing thereof, said instabilities being caused by the current flow. Another highly efficient possibility for increasing the maximum current of the cell consists in conducting a current of suitable direction and strength through the interior of the presumably hollow inner tube.

摘要： The present invention is used for the non-contact determination of velocity distributions of a liquid metal in a continuous casting die. A preferred field of application of the device is the velocity determination in the continuous casting of steel and aluminum, in particular during slab casting. The determination is carried out in that a primary magnetic field penetrates the liquid metal volume in the die, the magnetic fields induced by the movement of the fluid is measured, and based thereon the velocity is calculated by solving an inverse problem. The calculation employs the principle of least squares, wherein the mean square deviations of the magnetic fields induced by the assumed velocity from the measured values is used as the functional to be minimized. In the process, the Tikhonov regularization is used, wherein the mean square curvature of the velocity field or the mean square velocity is used as the regularization functional. Furthermore, the divergence freedom of the velocity field is ensured by utilizing an additional functional. The array comprises a coil system generating a magnetic field, a measuring and control unit for the fluxes in said coil system, by which the direction of the magnetic field in the fluid can be changed, a plurality of magnetic field sensors in the outer region of the fluid for determining the magnetic fields induced by the movement of the fluid, and means for signal forwarding, processing and representation.

摘要： The invention relates to a method and to a device for the electromagnetic stirring of electrically conductive fluids (2, 21, 22) in the liquid state and/or in the state of onsetting solidification of the fluid (2, 21, 22), using a rotating magnetic field that is produced in the horizontal plane of a Lorentz force (FL). The aim is to achieve an intensive three-dimensional flow on the inside of the fluid for mixing in the liquid state up to the direct vicinity of solidifying fronts, and to simultaneously ensure an undisturbed, free surface of the fluid. The solution is to change the direction of rotation (15, 16) of the magnetic field rotating in the horizontal plane at regular time intervals in the form of a period duration (TP), wherein the frequency of the directional change of movement of the magnetic field vector is adjusted such that in the state of mixing the liquid fluid (2, 21, 22) a period duration (TP) is adjusted between two directional changes of the magnetic field during a time interval (ΔTPM) as a function of the adjustment time (ti.a.) with the condition (I) 0.5.ti.a

摘要： The invention relates to a method and to a device for the electromagnetic stirring of electrically conductive fluids (2), using a magnetic field RMF (34) rotating in the horizontal plane and a magnetic field WMF (47) migrating in the vertical direction relative thereto. The aim is to avoid non-symmetrical flow structures in receptacles filled with melts, particularly at the onset and during the course of solidification. In addition, effective mixing of the fluid and/or controlled solidification of metal alloys are to be achieved, while avoiding the formation of segregation zones in the solidifying structure. The solution is that both the rotating magnetic field RMF (34) and the migrating magnetic field WMF (47) are discontinuously connected in the form of temporally limited and adjustable period durations (TP,RMF,TP,WMF) and alternately, consecutively in time, via associated induction coils (31, 32, 33; 41, 42, 43, 44, 45, 46).
