Description

Aus wasserdurchflossenen Vierkantrohren bestehende Spule für eisenlose Induktionsöfen Es sind schon verschiedene Vorschläge gemacht worden, um die Spulen, von eisenlosen Induktionsöfen in ihrer Lage zu halt-en und ein ausreichend steifes, durch die, Spulen gebildetes Gerüst herzustellen. Beispielsweisie ist es bekannt, an die Spulenivindungen Schraubenholzen anzulöten und über die Schraubenbolzen Leisten aus isolierendem Werkstoff zu sAleben und sie durch Schraub-en festzuhalten.Coil consisting of water-permeated square tubes for ironless ones Induction furnaces Various proposals have already been made to make the coils, of ironless induction furnaces in their position and a sufficiently rigid, by producing the framework formed by the coils. For example, it is known to solder screw bolts to the coil connections and over the screw bolt strips Made of insulating material and held in place with screws.

Den Gegenstand der Erfindung bildet eine Spule für eisenlose Induktionsöfen, die in an sich bekannter Weise aus wasserdurchflossenen Vierkantrohren besteht, die in bekannter Weise wendelförmig um den zu beheizenden Raum angeordnet werden. Gemäß der Erfindung sind die einzelnen Spulenmindungen mit radialen Bohrungen versehen, die mit den Windungen verlötete Röhrchen enthalten, in die elektrisch is#olierte Schraubenholzen eingesetzt sind, auf welchen an der Außens#eite des Ofens Streifen aus isolierendem Werkstoff durch Schraubenmuttern befestigt sind. Die Is-olation der Schraubenbolzen besteht aus einem zwischen dem Schraubenbolzen, und dem Röhrchen angebrachten zylinderförmigen Stück aus isolierendem Werkstoff.The subject of the invention is a coil for ironless induction furnaces, which in a known manner consists of square tubes through which water flows, which are arranged in a known manner in a helical manner around the room to be heated. According to the invention, the individual coil windings are provided with radial bores, which contain small tubes soldered with the windings, in which electrical insulation Bolts are inserted, on which strips on the outside of the stove made of insulating material are fastened by screw nuts. The isolation the screw bolt consists of one between the screw bolt and the tube attached cylindrical piece made of insulating material.

In der Zeichnung ist eine'Ausführungsform der Erfindung dargestellt. Mit a sind zwei übereinanderliegende Windungen einer aus Vierkantrohren bestehenden Hochfrequenzspule bezeichnet. Diese Windungen sind durchbohrt, und in die Bohrungen sind Röhrchen b eingesetzt, die aus demselben Werkstoff bestehen können wie die Vierkantrohre selbst. Das Röhrchenb ist mit den Vierkantrohren verlötet. ' In die Röhrchen b sind Schraubenbolzenc eingeführt, die gegen die Röhrchen b durch ein im wesentlichen zylinderförmiges Stück aus isolierendem Werkstoff d isoliert sind. Auf die übereinanderliegenden Schraubenbolzen c ist ein Streifen e aus isolierendem Werkstoff geschoben, und dieser Streifene wird gegen die Windungena durch die Schraubenf gepreßt.An embodiment of the invention is shown in the drawing. With a two superposed turns of a high-frequency coil consisting of square tubes are designated. These windings are drilled through, and tubes b are inserted into the bores, which tubes can consist of the same material as the square tubes themselves. The tube b is soldered to the square tubes. 'Are Schraubenbolzenc b to the tubes introduced, b against the tube by a substantially cylindrical piece of insulating material d are isolated. A strip e of insulating material is pushed onto the superposed screw bolts c, and this strip line is pressed against the turnsa by the screws f.
