 wasser zufolge der intensiven Hitze des Ofens auf seinem Wege von der Einströmstelle bis zur Austrittsstelle in der   Kühlspulo   verdampft und diese wie ein Dampferzeuger wirkt. 



   Nach vorliegender Erfindung wird dieser Nachteil dadurch beseitigt, dass das Kühlmittel durchwegs im flüssigen Zustande erhalten wird. Zu diesem Zwecke wird das Wasser an mehreren Stellon in die Kühlspule ein- und an mehreren Stellen von dieser abgeleitet, so

 während der elektrische Strom, wie   bisher. din aufeinanderfolgenden   Windungen der Spule der Reihe nach   durchfliesst.   



   In der Zeichnung ist eine beispielsweise Ausführungsform eines gemäss der Erfindung ausgebildeten Ofens dargestellt. a ist die das geschmolzene Metallbad aufnehmende Kammer, in welcher die   Sekundärströme   induziert worden, während b der das Bad durchsetzende Mittelteil des magnetischen Kernes ist. Dieser Korn ist von einer röhrenförmigen Wicklung c umgeben. Der Erregerstrom tritt, wie in der Zeichnung dargestellt, bei einem Ende der Spule ein und durchläuft die Windungen der Spule der Reihe nach bis zum anderen Ende. 



  Das   Kühlmittel   hingegen wird von irgend einer geeigneten Quelle aus an verschiedenen Punkten d in die Kühlspule eingeleitet und aus dieser von einer entsprechenden Anzahl korrespondierender Stellen e, die vorteilhaft auf der gegenüberliegenden Seite der Kühlspule liegen, abgeleitet, so dass das Wasser die verschiedenen Windungen der Spule nicht eine nach der anderen,   sondern alte zu gleicher   Zeit   durchfliesst,   d. h. die verschiedenen Windungen der Spule sind bezüglich des sie durchfliessenden Wasserstromes in Parallelverbindung. 



   Dadurch ist das Kühlmittel der Hitze des Ofens nur für eine kurze Zeit unter-   worfen und bleib@ infolgedessen immer   im flüssigen Zustande.

 EMI1.1
 



   The invention relates to electrical induction furnaces in which the windings of the primary or excitation coil are tubular in order to circulate a current
 EMI1.2
 As a result of the intense heat of the furnace, water evaporates on its way from the inflow point to the outlet point in the cooling coil, which acts like a steam generator.



   According to the present invention, this disadvantage is eliminated in that the coolant is consistently maintained in the liquid state. For this purpose, the water is fed into the cooling coil at several Stellon and diverted from it at several points, see above
 EMI1.3
 while the electric current, as before. d in successive turns of the coil flows through in sequence.



   The drawing shows an example of an embodiment of a furnace designed according to the invention. a is the chamber containing the molten metal bath, in which the secondary currents have been induced, while b is the central part of the magnetic core penetrating the bath. This grain is surrounded by a tubular coil c. As shown in the drawing, the excitation current enters at one end of the coil and runs through the turns of the coil in sequence to the other end.



  The coolant, on the other hand, is introduced into the cooling coil from any suitable source at various points d and is derived therefrom from a corresponding number of corresponding points e, which are advantageously on the opposite side of the cooling coil, so that the water flows through the various turns of the coil not one after the other, but old flows through at the same time, d. H. the different turns of the coil are connected in parallel with regard to the water flow flowing through them.



   As a result, the coolant is only exposed to the heat of the oven for a short time and therefore always remains in a liquid state.
