Elektrischer Schmelzofen.
Die Erfindung bezieht sich auf einen elektrischen Tiegelschmelzofen und betrifft Ausgestaltungen der Kontakte des Schmelztiegels.
Die Zeichnung veranschaulicht eine Ausführungsform des Erfindungsgegenstandes in Fig. 1 und 2 im Schema bezw. in Perspektive. Der Schmelzofen besitzt in bekannter Weise einen Schmelztiege) g, der durch Kontakte mit der Sekundärwicklung eines Transformators t verbunden ist, dessen Primärwicklung unter Zwischenschaltung eines Umschalters s an eine elektrische Stromquelle q angeschlossen ist. Die Kontakte sind gemäiJ der Erfindung als den Tiegel zwischen sich fassende, feststellbare Greifer ausgebildet, wodurch ermöglicht wird, die üblichen Schmelztiegel ohne Adaptierung oder Umwandlung ihrer Gestalt verwenden zu können.
Besonders vorteilhaft ist die Ausführungsform, wenn der eine Greifer als Teller zum Tragen des Tiegels und der andere Greifer als Deckel von zweckmässig haubenförmige Gestalt ausgebildet ist. Zur Feststellung der Greifer ist der eine, z. B. der obere Greifer mittels einer durch ein Handrad h verstellbaren Druckschraube oder dgl. einstellbar.
Um die Besichtigung des Schmelzgutes während des Schmelzens ohne Belästigung des Arbeiters durch die unmittelbare Hitzeausstrahlung zu ermöglichen, ist der obere Greifer mit entsprechenden Aussparungen versehen.
Beide Greifer bezw. deren Arme sind mit Höhlungen versehen, die an eine Rohrleitung w zur Durchführung eines Kühlmittels, wie Wasser, angeschlossen sind, wodurch der Transformator gegen Erhitzung von Seiten des Schmelztiegels geschützt wird.
PATENT-ANSPRÜCHE :
1. Elektrischer Schmelzofen mit durch Kontakte an die Sekundärwicklung eines Transformators angeschlossenem Schmelztiegel, dadurch gekennzeichnet, dass die Kontakte als den Tiegel ( zwischen sich fassende, feststellbare Greifer (k) ausgebildet sind, wodurch ermöglicht wird, die üblichen Schmelztiegel ohneweiters in dem Ofen verwenden zu können.

Electric melting furnace.
The invention relates to an electric crucible melting furnace and relates to configurations of the contacts of the crucible.
The drawing illustrates an embodiment of the subject matter of the invention in FIGS. 1 and 2 respectively in the scheme. in perspective. The melting furnace has, in a known manner, a crucible) g which is connected by contacts to the secondary winding of a transformer t, the primary winding of which is connected to an electrical power source q with a changeover switch s interposed. According to the invention, the contacts are designed as lockable grippers gripping the crucible between them, which makes it possible to use the usual melting crucibles without adapting or converting their shape.
The embodiment is particularly advantageous when one gripper is designed as a plate for carrying the crucible and the other gripper is designed as a cover, suitably dome-shaped. To determine the gripper is one, z. B. the upper gripper by means of a pressure screw adjustable by a handwheel h or the like. Adjustable.
The upper gripper is provided with appropriate recesses in order to enable inspection of the material to be melted during the melting process without disturbing the worker due to the direct heat radiation.
Both grippers respectively. the arms of which are provided with cavities which are connected to a pipe w for the passage of a coolant such as water, whereby the transformer is protected against heating from the side of the crucible.
PATENT CLAIMS:
1. An electric melting furnace with a crucible connected to the secondary winding of a transformer by contacts, characterized in that the contacts are designed as the crucible (between them gripping, lockable gripper (k), which makes it possible to use the usual crucibles in the furnace without further ado can.
