Description

Form zur Herstellung eiserner Walzen Die.Erfiridung betrifft eine Form zur Herstellung eiserner Walzen, bei welcher ein Erhitzen der eingesetzten 'feile durch Induktionsströme erfolgt, nach Patent 528 17q-Der Erfindung gemäß wird die zur Erhitzung der Induktionsströme dienende Spule in die den zu erhitzenden. Teil umgebende Formwand eingebettet, und zwar erfolgt die Einbettung der Induktionsspule so dicht an dem Werkstück, wie es die Hitzewirkung zuläßt. Hierdurch wird der Querschnitt des Streufeldes der Induktionslinien im Innern der Spule so klein wie möglich gestaltet und dadurch der nützliche Induktionsfuß und damit der Wirkungsgrad wesentlich erhöht, ohne daß irgendwelche schädliche Einflüsse eintreten.Mold for making iron rollers Die.Erfiriden concerns a Form for the production of iron rollers, in which a heating of the used 'filing takes place by induction currents, according to patent 528 17q-The invention is according to the coil used to heat the induction currents into the coil to be heated. Part of the surrounding mold wall is embedded, namely the embedding of the induction coil as close to the workpiece as the heat effect allows. This creates the cross-section the stray field of the induction lines inside the coil is made as small as possible and thereby the useful induction base and thus the efficiency significantly increased, without any harmful influences occurring.

Auf der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt.The drawing shows an example of an embodiment of the subject matter of the invention shown.

Abb. i zeigt einen Schnitt durch eine gemäß der. Erfindung ausgebildete Form. Abb.2 zeigt einen Schnitt längs der Linie II-II der Abb. i.Fig. I shows a section through a according to the. Invention trained Shape. Fig.2 shows a section along the line II-II of Fig. I.

Die Form besteht, wie in dem Hauptpatent beschrieben, aus einem Unterkasten i, einem mittleren Kasten 2 und einem Oberkasten 3. In diese Kästen wird entweder der zunächst fertiggestellte Kern oder5 wie in vorliegendem Beispiel dargestellt, der in einem anderen Verfahren hergestellte Walzenmantel eingesetzt, worauf dann der Kern eingegossen wird. Vor dem Eingießen wird der Mantel durch Induktionsströme erhitzt, .um so eine gute Verschweißung des Mantels mit dem einzugießenden Kern zu erhalten. Nach dem Eingießen, das durch das Rohr 5 erfolgt, wird die Erhitzung weiter fortgesetzt, so daß eine Absonderung der Schlacke und eine gute Verschweißung gewährleistet ist. Die Erwärmung erfolgt mittels einer Induktionsspule 6, welche in den mittleren Formkasten 2, welcher aus Asbestzementmasse hergestellt sein kann, eingebettet ist. Die Anordnung der Induktionsspule erfolgt so dicht wie irgend möglich an dem zu erhitzenden Werkstück. Von der Spule führen die beiden Enden 7 aus der Form heraus. Zwischen der Innenwand des Formkastens 2 und dem zu erhitzenden Mantel ¢ ist noch eine Schicht 8 aus Formsand oder Formmasse aufgestampft, die verhältnismäßig dünn ist und zur Wärmeisolierung dient.As described in the main patent, the shape consists of a sub-box i, a middle box 2 and an upper box 3. In these boxes either the initially completed core or5 as shown in the present example, the roll shell produced in another process is used, whereupon the core is poured in. Before pouring, induction currents are applied to the jacket heated, in order to ensure a good welding of the jacket with the core to be cast to obtain. After the pouring, which takes place through the pipe 5, the heating continued, so that a separation of the slag and a good weld is guaranteed. The heating takes place by means of an induction coil 6, which in the middle molding box 2, which can be made of asbestos-cement mass, is embedded. The induction coil is arranged as close as possible on the workpiece to be heated. The two ends 7 of the coil lead out of the Shape out. Between the inner wall of the molding box 2 and the jacket to be heated ¢ a layer 8 of molding sand or molding compound is still tamped on, which is relatively is thin and is used for thermal insulation.
