Patentiert im Deutschen Reiche vom 29. April 1910 ab. Patented in the German Empire on April 29, 1910 .
Vorliegende Erfindung bezieht sich auf einen elektrischen Schmelzofen mit Vorrichtung zur selbsttätigen Regelung der durch Induktion in einem elektrischen Ofen entwickelten Hitze.The present invention relates to an electric melting furnace and apparatus for the automatic regulation of the developed by induction in an electric furnace Heat.
Die neben der Erhitzung des Schmelzgutes durch- Widerstand und Lichtbogen zur Steigerung der Hitze zur Verwendung kommende Induktionsspule kann je nach Wunsch in ge- xo nanntes Gut eingeführt oder davon entfernt werden. Ferner sind Vorkehrungen getroffen, um die Induktionsspule zu kühlen und durch einen mit einem Hitzemesser verbundenen Apparat die Tätigkeit derselben selbsttätig nach Wunsch zu regeln.The throughput in addition to the heating of the melt resistance and arc to increase the heat for use next induction coil can as desired in overall xo-called Good imported or locally from it. Furthermore, precautions are taken to cool the induction coil and to regulate the activity of the same automatically as desired by means of an apparatus connected to a heat meter.

Fig. 2 ist ein Schnitt durch die Induktionsspule nach der Linie 2-2 der Fig. 1.FIG. 2 is a section through the induction coil along line 2-2 of FIG. 1.
Fig. 3 ist ein Schnitt nach der Linie 3-3 der Fig. 2.FIG. 3 is a section along line 3-3 of FIG.
Fig. 4 ist die schaubildliche Ansicht einer der blätterförmigen Platten, welche die Induktionsspule umgeben.Figure 4 is a perspective view of one of the leaf-shaped plates which make up the induction coil surround.
Der elektrische Schmelzofen A besteht ausThe electric melting furnace A consists of
den Wänden 10 und 11, durch welche die Elektroden B und C beliebiger zweckdienlicher Art sich erstrecken. Diese Elektroden sind imstande, die Beschickung entweder durch den in derselben entwickelten Widerstand selbst oder durch einen zwischen den Spitzen der Elektroden sich bildenden Lichtbogen zuthe walls 10 and 11 through which electrodes B and C of any convenient type extend. These electrodes are capable of charging either through the resistance developed in them themselves or through an arc which forms between the tips of the electrodes
erhitzen. ■heat. ■
Um das Beschickungsmaterial außer seiner Erhitzung durch Widerstand oder Lichtbogen auch durch Induktion erhitzen zu können, ist eine Induktorspule D vorgesehen, welche über dem Ofen so angebracht ist, daß sie zwecks Regulierung der entwickelten Hitze gehoben und gesenkt werden kann.In order to be able to heat the charge material by induction in addition to being heated by resistance or arcing, an inductor coil D is provided which is mounted above the furnace so that it can be raised and lowered for the purpose of regulating the heat developed.
Wie dargestellt, wird diese Spule von einer Kette 12 getragen, die über die Seilscheiben 13 und 14 einer geeigneten Winde 15 läuft, die von einem Elektromotor 16 betätigt wird.As shown, this spool is carried by a chain 12 that runs over the pulleys 13 and 14 of a suitable winch 15 is running, which is operated by an electric motor 16.
Zur selbsttätigen Regelung der. Hitze im Ofen, so daß derselbe gleichmäßig eine bestimmte Temperatur beibehält, wird der Motor mit einer geeigneten Vorrichtung bekannter Art verbunden, die von einem in den Ofenwänden vorgesehenen Hitzemesser 17 aus geregelt wird, so daß, wenn die im Ofen entwickelte Hitze einen bestimmten Grad überschreitet, die Induktorspule angehoben, und falls die Temperatur im Ofen unter einen bestimmten Grad fällt, gesenkt wird.For automatic regulation of the. Heat in the oven so that the same evenly a certain Temperature maintains, the motor is connected to a suitable device of known type, which is from one in the Oven walls provided heat meter 17 is regulated out so that when the developed in the oven Heat exceeds a certain level, the inductor coil is raised, and if the temperature in the furnace falls below one falls to a certain degree, is lowered.
Die Induktorspule selbst besteht aus einer ringförmigen Leitungsspule 18, deren Enden 19 und 20 nach einer hier nicht dargestellten Kraftquelle geleitet sind.The inductor coil itself consists of an annular line coil 18, the ends 19 of which and 20 are directed to a power source, not shown here.
Diese Spule ist von einem Ring 22 aus weichem Blatteisen umgeben, und das Ganze sitzt in einem Gehäuse 23 aus feuerfestem Material, z. B. feuerfesten Mauersteinen.This coil is surrounded by a ring 22 made of soft sheet iron, and the whole sits in a housing 23 made of refractory material, e.g. B. refractory bricks.
Um das Innere des Ofens zu kühlen und ein Ausbrennen des Leiters zu verhindern, ist in der Mitte der Spule 18 ein Rohr 24 für die Zirkulation von Wasser vorgesehen, dessen Enden 25 und 26 nach der Außenseite der Spule führen und mit einem geeigneten Wasserbehälter verbunden sind.To cool the inside of the furnace and prevent the conductor from burning out, a pipe 24 is provided in the middle of the coil 18 for the circulation of water, its ends 25 and 26 lead to the outside of the coil and with a suitable Water tanks are connected.
