Der 4. Februar ist der \"National Create a Vacuum Day\", und Ipsen ist stolz darauf, dies zu feiern und eine h\u00e4ufig gestellte Frage zu beantworten: Warum einen Vakuumofen verwenden?<\/p>\n\n\n\n

\n\n\n\n

Die Menschen schmieden schon seit Ewigkeiten Metall. Buchst\u00e4blich.<\/p>\n\n\n\n

Von der Bronzezeit bis zur Eisenzeit haben die Fortschritte in der Metallurgietechnik den Aufstieg der Zivilisationen und die Ausbreitung der Menschheit gepr\u00e4gt. Schwerter wurden im Feuer geschmiedet, im Wasser abgeschreckt, mit Kohlenstoff legiert und von Waffenschmieden in Form geh\u00e4mmert. Die Armee mit den besten Waffen und der effektivsten R\u00fcstung hatte in Kriegen einen erheblichen Vorteil. Die F\u00e4higkeit, ein Gebiet anzugreifen oder zu verteidigen, hing oft von den F\u00e4higkeiten der Metallarbeiter in der Waffenkammer ab.<\/p>\n\n\n\n

Mit dem technologischen Fortschritt wurde auch das Schmelzen und Legieren von Metallen weiterentwickelt. W\u00e4hrend der industriellen Revolution verlangten die Flie\u00dfb\u00e4nder nach gleichbleibenden Materialien und regelm\u00e4\u00dfigem Nachschub. In den USA waren die riesigen Stahlwerke mit ihren geschmolzenen Metallen, die man schon von weitem gl\u00fchen sehen konnte, eine wesentliche Voraussetzung f\u00fcr die Schaffung von Transportmitteln, die den Kontinent und sp\u00e4ter die Welt erschlossen.<\/p>\n\n\n\n

In den fr\u00fchen 20th<\/sup> Jahrhundert begannen Radio und Fernsehen mit dem Einsatz von Vakuumr\u00f6hren, w\u00e4hrend die elektrische Gl\u00fchbirne die Erzeugung eines Vakuums um ein elektrifiziertes lichtemittierendes Element - in der Regel Wolfram - erforderte. Etwa zur gleichen Zeit begannen Experimente mit Vakuum\u00f6fen, die die M\u00f6glichkeit industrieller Anwendungen aufzeigten, und 1929 gab die Raytheon Corporation ihren ersten Auftrag f\u00fcr einen Vakuumofen auf. <\/p>\n\n\n\n

\n
\n
\"Black
1960er Jahre Ipsen-Vakuum\u00f6fen<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n

Im Jahr 1959 experimentierte Harold Ipsen in Rockford, Illinois, mit seinem eigenen Vakuumofen. Ipsen entwarf Hei\u00dfzonen, l\u00f6ste Abschreckprobleme und experimentierte mit Inertgasen, um Sauerstoff und Wasserdampf effizient zu eliminieren. Er erkannte, dass die Technologie der Vakuum\u00f6fen eine ernstzunehmende Gr\u00f6\u00dfe werden w\u00fcrde.<\/p>\n\n\n\n

Vakuum\u00f6fen waren in der Lage, einem Metallteil W\u00e4rme zuzuf\u00fchren, um seine Gitterstruktur zum H\u00e4rten, Altern oder Spannungsabbau zu ver\u00e4ndern, oder sie konnten ein Metall mit einem anderen Metall durch Verfahren wie L\u00f6ten verbinden. Durch die Eliminierung von Sauerstoff und Wasser wurden Rost und andere Metalloxide vermieden, und die vakuumw\u00e4rmebehandelten Teile wurden sauber und gl\u00e4nzend. Je effizienter das Vakuum ist, desto sauberer und gl\u00e4nzender sind die Teile.<\/p>\n\n\n\n

In den 1960er Jahren f\u00fchrte das Weltraumrennen zu einem sprunghaften Anstieg der Nachfrage nach Pr\u00e4zisionsmetalllegierungen und der Verwendung seltener und exotischer Metalle. Vakuum-W\u00e4rmebehandlungstechnologien wurden eingesetzt, um sicherzustellen, dass Teile mit einem hohen Ma\u00df an Genauigkeit und Zuverl\u00e4ssigkeit hergestellt werden konnten. Wenn es um die bemannte Raumfahrt geht, sind Vorhersagbarkeit und Zuverl\u00e4ssigkeit von entscheidender Bedeutung.<\/p>\n\n\n\n

Anwendungen f\u00fcr saubere und zuverl\u00e4ssige Teile fanden auch ihren Weg in die Medizin und halfen, das Problem des Gelenkverschlei\u00dfes zu l\u00f6sen, insbesondere bei Knien und H\u00fcften. Die M\u00f6glichkeit, aus Kobalt-Chrom-, Titan-, Zirkonium- und Nickellegierungen haltbare und dauerhafte Ersatzgelenke herzustellen, die selbst auf mikroskopischer Ebene sauber sind, machte Vakuum\u00f6fen zu einer wichtigen medizinischen Ressource.<\/p>\n\n\n\n

Die pr\u00e4zise Steuerung, die ein Vakuumofen bietet, um eine bessere Gleichm\u00e4\u00dfigkeit von einem Prozess zum n\u00e4chsten zu erreichen, um gewundene Geometrien zu l\u00f6ten, um das Entl\u00f6ten zu steuern, um Alpha- und Beta-Phasen zu kontrollieren und um eine wirksame Steuerung der Einsatztiefe beim Aufkohlen und Nitrieren aufrechtzuerhalten, macht den Vakuumofen unentbehrlich f\u00fcr Industrien, die auf ein hohes Ma\u00df an Konsistenz mit sehr spezifischen metallurgischen Eigenschaften angewiesen sind.<\/p>\n\n\n\n

Die Hersteller stellten fest, dass Teile, die in einem Vakuumofen bearbeitet wurden, oft keine umfangreiche Nachbehandlung durch Reinigung oder zus\u00e4tzliche Bearbeitung ben\u00f6tigten. Es war nicht notwendig, Teile, die in einem Vakuumofen bearbeitet wurden, zu sandstrahlen oder zu polieren. Es bestand eine geringere Abh\u00e4ngigkeit von Abschreck\u00f6len, Acetylen oder endothermen Gasgeneratoren. Das Verfahren, das in erster Linie durch interne elektrische Heizelemente mit einer durch ein Wasserkreislaufsystem geregelten Au\u00dfentemperatur angetrieben wird, hat keine offenen Flammen und keine damit verbundenen D\u00e4mpfe oder Ru\u00df. Mit Vakuum\u00f6fen konnten W\u00e4rmebehandlungsanlagen zu sauberen, temperaturgeregelten Lagern werden, die die Umwelt weit weniger belasteten.<\/p>\n\n\n\n

Warum verwenden wir also Vakuum\u00f6fen? Weil die Vakuumofentechnologie uns dabei hilft, weiter zu gehen und l\u00e4nger zu leben als je zuvor. Und weil die erfolgreichsten menschlichen Unternehmungen immer damit beginnen, dass wir unseren Vision\u00e4ren, Ingenieuren, Konstrukteuren und Betreibern die beste Technologie zur Verf\u00fcgung stellen, die wir herstellen k\u00f6nnen.<\/p>\n\n\n\n
