Description
Die Erfindung bezieht sich auf einen Wanderfeldinduktor mit einem lameilierten genuteten Induktorblechpaket, in dessen Nuten jeweils übereinander zwei kühlmitteldurchflossene rohrförmige Leiter einer mehrphasigen Induktorwicklung zur Erzeugung eines elektromagnetischen Wanderfeldes angeordnet sind, bei dem die Höhe des an der Nutöffnung liegenden Leiters praktisch gleich der Eindringtiefe des elektromagnetischen Feldes im Leitermaterial ist und der Kühlkanal des am Nutgrund liegenden Leiters in diesem eine zum Nutgrund verschobene exzentrische Lage einnimmt, nach Patent 19 06 922.The invention relates to a traveling field inductor with a laminated, grooved inductor core, in its grooves, two tubular conductors of a multiphase through which coolant flows, one on top of the other Inductor winding for generating a traveling electromagnetic field are arranged at that the height of the conductor lying at the slot opening is practically equal to the penetration depth of the electromagnetic one Field is in the conductor material and the cooling channel of the conductor lying on the groove base in this one to the Groove base assumes a shifted eccentric position, according to patent 19 06 922.
Der in dem Hauptpatent beschriebene Induktor weist den Vorzug auf, daß sowohl die in dem an der Nutöffnung liegenden Le:ter entstehenden Wirbelstromverluste als auch die durch die Stromverdrängung bedingten Verluste in den am Nutgrund liegenden Leitern so stark verringert werden, daß der elektrische Wirkungsgrad der Induktoranordnung bei einer an sich gegebenen Anordnung auf ein Höchstmaß gebracht werden kann.The inductor described in the main patent has the advantage that both in the region lying at the groove opening Le: ter resulting eddy current losses, caused by the skin effect losses in the past on the groove base conductors so greatly reduced and that the electrical efficiency of the inductor can be brought to a maximum in a given arrangement.
Erfindungsgemäß wird daher in Ausgestaltung der Erfindung nach dem Hauptpatent vorgeschlagen, Wanderfeldinduktoren der eingangs näher bezeichneten Bauart als Rührspulen für Metallschmelzen zu verwenden.According to the invention it is therefore proposed in an embodiment of the invention according to the main patent, Traveling-field inductors of the type described in more detail at the beginning as stirring coils for molten metal use.
Der Betrieb von Induktoren als Rührspulen für Metallschmelzen erfordert eine im Regelfalle sehr hohe elektrische Stromdichte innerhalb des Lehermaterials der Induktonvicklung, weshalb sich nach dem Hauptpatent ausgebildete Induktoren besonders als Rührspulen für Metallschmelzen eignen.The operation of inductors as stirring coils for molten metal usually requires a very high level electrical current density within the teaching material of the inductor winding, which is why according to the main patent trained inductors are particularly suitable as stirring coils for molten metal.

ίο Wanderfeldinduktor nach dem Hauptpatent angeordnet Das Blechpaket des Induktors ist mit 14 und die in den Nuten des Blechpakets gelegenen Leiter sind mit 9 und 10 bezeichnet. Die Leiter sind jeweils in üblicher Weise im Wickelkopf 15 zu einer Induktonvicklung verbunden. Um bei einem Durchbruch der feuerfesten Zustellung 11 eine Zerstörung der Induktonvicklung durch das Austreten des flüssigen Metalls zu vermeiden, ist zwischen dem Boden der Zustellung U und dem Induktor ein Trennblech 16 aus unmagnetischem Material angeordnet, welches seinerseits vom Induktor durch eine Schicht aus isoliertem Material getrennt ist.ίο Traveling field inductor arranged according to the main patent The laminated core of the inductor is marked with 14 and the conductors located in the grooves of the laminated core are marked with 9 and 10 denotes. The conductors are each in the usual manner in the end winding 15 to form an inductive winding tied together. In order to destroy the inductor winding in the event of a breakthrough in the refractory lining 11 to avoid the escape of the liquid metal is between the bottom of the infeed U and the Inductor a separating sheet 16 made of non-magnetic material is arranged, which in turn from the inductor is separated by a layer of insulated material.
Zur Rührung der im Ofengefäß befindlichen Metallschmelze 17 ist der Induktor so geschaltet, daß er ein senkrecht aus der Zeichenebene fortschreitendes elektromagnetisches Wanderfeld erzeugt Im Bereich der Eindringtiefe dieses Wanderfeldes wird in der Metallschmelze 17 eine durch 18 angedeutete Strömung gleicher Richtung erzeugt, die in den übrigen Bereichen der Schmelze einen Rückfluß in etwa entgegengesetzter Richtung zur Folge hat. Durch die Wandwirkung der Ofenzustellung begünstigt, werden dabei zusätzliche Strömungskomponenten hervorgerufen, derart, daß insgesamt eine sehr wirkungsvolle Rührung der Metallschmelze 17 erreicht wirdTo stir the molten metal 17 in the furnace vessel, the inductor is switched so that it is on Electromagnetic traveling field advancing vertically out of the plane of the drawing generated in the area The penetration depth of this traveling field becomes a flow indicated by 18 in the molten metal 17 In the same direction, the reflux in the remaining areas of the melt is roughly opposite Direction entails. The wall effect of the furnace lining promotes additional Caused flow components, so that overall a very effective stirring of the Molten metal 17 is reached
