Description

Man hat massive Eisenplatten dadurch induktiv erwärmt, daß man zwischen die Platten eiserne Rippen eingefügt und in die dadurch entstandenen Hohlräume die isolierten Stromleiter eingelegt hat; die freien Enden wurden außerhalb der Platten in Reihenschaltung miteinander verbunden. Die durch diese Anordnung bedingte schlechte Kopplung, die große Streuung der Stirnverbindungen und die Luftspalte zwischen Rippen und Platten verursachen einen schlechten Leistungsfaktor.Solid iron plates were inductively heated by placing between iron ribs inserted into the plates and the has inserted an insulated conductor; the free ends were outside the panels connected in series. The bad one caused by this arrangement Coupling, the large spread of the end connections and the air gaps between ribs and disks cause a poor power factor.

Gemäß Erfindung werden zwei Eisenplatten verwendet, in welche die Nuten für die Stromleiter je zur Hälfte eingeschnitten sind. Die Stoßstellen der Platten werden genau aufgepaßt und plan geschliffen, so -daß ein einwandfreier Übergang der im Eisen induzierten magnetischen Flüsse gewährleistet ist. Die Stromleiter selbst «-erden zweckmäßig mit einem isolierenden Überzug versehen, wie er beispielsweise durch anodische Oxydation erzeugt «-erden kann. Der Stromleiter erhält eine mäanderartige Form und kann aus einem einzigen Stück hergestellt werden, so - daß der Leiter genau in die Nuten eingelegt werden kann und vollständig zwischen den beiden Platten liegt. Um eine sehr gleichmäßige Erwärmung der Platten zu erreichen, soll die Zwischenschicht zwischen zwei nebeneinanderliegenden Leitern etwa dic dreifache Eindringtiefe des Feldes nicht überschreiten. Bei großen Leistungen wird er Stromleiter zweckmäßig in Schleifen geführt. Hier muß jedoch der Leiter auf der einen Seite wegen der entstehenden Kreuzungen herausgeführt werden.According to the invention, two iron plates are used in which the Grooves for the conductors are cut in half. The joints of the Plates are fitted exactly and sanded flat, so that a perfect transition the magnetic flux induced in the iron is guaranteed. The conductors itself «-earth expediently provided with an insulating coating, such as he generated by anodic oxidation «-can earth. The conductor has a meandering shape Shape and can be made from a single piece, so - that the conductor is accurate can be inserted into the grooves and lies completely between the two plates. In order to achieve a very even heating of the plates, the intermediate layer between two adjacent conductors about three times the penetration depth of the Do not exceed the field. In the case of large powers, it is useful as a conductor led in loops. Here, however, the conductor must be on the one hand because of the resulting Intersections are brought out.

Abt). i veranschaulicht die Ausrüstung mit einem mäanderförmigen Leiter im waagerechten Schnitt B-B; Mb. -2 zeigt einen Querschnitt in der Ebene A-A. In Abb. i und 2 stellt 2 die untere Platte mit Nuten 3 beispielsweise halbkreisförmigen Querschnitts dar. An sich können die Nuten jede beliebige -Form besitzen. Die obere Fläche gegenüber der Platte i ist genau plan geschliffen. Inder Nut 3 liegt der isolierte Leiter 4.. -Man verwendet hierfür zweckmäßig eloxierte Aluminiumleiter oder auch alumetierte Kupferleiter, die eloxiert sind. Die obere Platte i wird nach Einlegen des geformten Leiters .4 aufgelegt und in geeigneter Weise finit der unteren Platte 2 fest verbunden.Abbot). i illustrates the equipment with a meander-shaped ladder in the horizontal section BB; M b. -2 shows a cross-section in the plane AA. In Figs. I and 2, 2 shows the lower plate with grooves 3, for example, with a semicircular cross-section. As such, the grooves can have any shape. The upper surface opposite the plate i is ground exactly flat. The insulated conductor 4 is located in the slot 3. For this purpose, anodized aluminum conductors or aluminum-coated copper conductors that are anodized are used. The upper plate i is placed after inserting the shaped conductor .4 and firmly connected finitely to the lower plate 2 in a suitable manner.

Abb.3 zeigt die Ausführung mit geschlossenen Schleifen. In die beiden Platten 3 und h sind wieder zueinander passende halbkreisförmige Nuten j eingeschnitten, welche den isolierten Stromleiter 8 aufnehmen.Figure 3 shows the version with closed loops. In the two plates 3 and h, matching semicircular grooves j are cut again, which receive the insulated conductor 8.

Die Anordnungen ergeben wegen der engen Kopplung von Sekundär- und Primärkreis und der geringen Streuung einen guten Leistungsfaktor. Wenn inan als Stromleiter Rohre verwendet, so ist zugleich die Möglichkeit einer raschen und wirksamen Kühlung gegeben, was bei zielen Preßvorgängen besonders wertvoll ist. Die Form des Stromleiters kann den Erfordernissen angepaßt werden, also beispielsweise auch rechteckig sein.The arrangements result because of the close coupling of secondary and Primary circuit and the low dispersion a good power factor. If inan as Conductor pipes used, so is at the same time the possibility of rapid and effective Given cooling, which is particularly valuable in targeted pressing processes. The shape of the Conductor can be adapted to the requirements, so for example also rectangular be.
