Description

  

  Verfahren zur Behandlung von Roh-, Halb- und Fertigfabrikaten aus Stoen  kristallinischer Struktur, insbesondere Metalle und Metallegierungen, zwecks  Beeinflussung ihrer Struktur und ihrer Eigenschaften.    Es ist bekannt, dass wenn Roh-,     Halb-          und    Fertigfabrikate, insbesondere Metall  fabrikate, zwecks Formgebung mechanischen  Kräften ausgesetzt werden, gleichzeitig- ge  wisse Eigenschaften (mechanische, physika  lische etc.) gewollt oder ungewollt ver  ändert werden. Es ist weiter bekannt, dass  diese Veränderungen wieder rückgängig ge  macht oder     geändert    werden können, indem  die Stoffe einer Wärme- oder Kältebehand  lung durch Glühen, Anlassen, Abschrecken  usw. ausgesetzt werden. Es können auch  durch Glühen, Anlassen, Abschrecken usw.

    allein, ohne vorherige Bearbeitung andere  Eigenschaften in Stoffen erreicht werden.  



  Das vorliegende Verfahren bezweckt nun,  alle diese     Wirkungen,    die bisher zum Bei  spiel durch Wärme- oder Kältebehandlung  erzielt wurden, besser und wirtschaftlicher  dadurch zu     erreichen,    dass die zu behandeln  den Körper oder Stoffe kristallinischer Struk  tur durch Hochfrequenz erzeugten Wirbel-    strömen ausgesetzt werden, wobei eine Fre  quenz von wenigstens 300 Perioden ange  wendet wird.  



  Das Verfahren     kann    überall dort gleich  zeitig oder nachträglich angewandt werden,       w6    irgendwelche Stoffe     kristallinischer     Struktur durch irgendeine Bearbeitung un  ter Energieaufwand (Schmelzen,     Drücken,     Ziehen, Pressen, Walzen, Schneiden usw.)  geformt oder beansprucht werden.

   Als Bei  spiel sei     angeführt:    Man; walzt eine     Messing-          platte    bis zur Grenze ihrer Festigkeit, setzt  diese Messingplatte dann den Strömen aus,  und sie wird nach ganz kurzer Zeit (wie  Versuche zeigen, etwa nach     S-0    bis GO Se  kunden) ihre alten ;mechanischen Eigen  <I>s</I>     a        'haft        en        und        ein        ganz        feines        Korngefüge        C     besitzen, so dass der Walzvorgang sofort er  neut vor sich gehen kann.  



  Gegebenenfalls wird es zweckmässig sein,  die Ströme während des Bearbeitungsvor  ganges wirken zu lassen, so     dass    der Bearbei-      tungsvorgang (Giessen, Walzen, Pressen etc.)  kontinuierlich durchgeführt werden kann.  Im Gegensatz hierzu ist es aber auch mög  lich, die durch eine vorhergehende Bearbei  tung erzielten Eigenschaften durch entspre  chende Durchleitung des Stromes noch zu  verstärken oder sonstwie zu verändern.  



  Bei Bearbeitung von Messinggegenständen  unter Anwendung von Wirbelströmen ist  es möglich, während der Einwirkung der  Ströme auf den Gegenstand gleichzeitig  auch die das Oxydieren verhindernden  Gase oder Vakuum einwirken zu lassen,  so dass es     zum    Beispiel     einwandfrei    ge  lingt, eine Messingplatte oxydfrei zu 'bear  beiten und oxydfrei abzukühlen, ohne die  bisher hierzu erforderlichen umständlichen  Apparate und ohne die bisher entstehender.  grossen Wärmeverluste. Dasselbe gilt natür  lich für alle andern oxydierenden Stoffe.  Das neue Verfahren gibt bei zweckentspre  chender Auswahl der Einwirkungsfaktoren  die Möglichkeit, insbesondere Metalle und  Metallegierungen spannungs- und zum Teil  korrosionsfrei herstellen zu können.  



  Da die     Beeinflussung    durch die Ströme  nur kurze Zeit zu erfolgen hat, so ist er  sichtlich, dass durch dieses Verfahren auch  eine erhebliche     Produktionsbeschleunigung     und dadurch eine erhebliche     Reduzierung    der  erforderlichen     Umlaufsmengen    erfolgt.



  Process for the treatment of raw, semi-finished and finished products made of materials with a crystalline structure, in particular metals and metal alloys, for the purpose of influencing their structure and their properties. It is known that when raw, semi-finished and finished products, in particular metal products, are exposed to mechanical forces for the purpose of shaping, certain properties (mechanical, physical, etc.) are deliberately or unintentionally changed at the same time. It is also known that these changes can be reversed or changed by exposing the substances to a heat or cold treatment by annealing, tempering, quenching, etc. It can also be done by annealing, tempering, quenching, etc.

    alone, without prior processing, other properties can be achieved in substances.



  The aim of the present method is to achieve all of these effects, which were previously achieved, for example, by heat or cold treatment, better and more economically by exposing the body or substances of crystalline structure to be treated to eddy currents generated by high frequency, a frequency of at least 300 periods being applied.



  The process can be applied simultaneously or retrospectively wherever any material with a crystalline structure is shaped or stressed by any kind of energy-intensive processing (melting, pressing, drawing, pressing, rolling, cutting, etc.).

   The following is an example: Man; If a brass plate rolls to the limit of its strength, this brass plate is then exposed to the currents, and after a very short time (as experiments show, after about S-0 to GO seconds) it will retain its old mechanical properties </I> a 'and have a very fine grain structure C, so that the rolling process can start again immediately.



  It may be useful to let the currents act during the machining process so that the machining process (casting, rolling, pressing, etc.) can be carried out continuously. In contrast to this, however, it is also possible, please include, to reinforce or otherwise change the properties achieved by previous processing by passing the current through.



  When machining brass objects using eddy currents, it is possible, while the currents act on the object, to simultaneously let the gases or vacuum prevent oxidation act, so that, for example, a brass plate can be machined and oxide-free To cool down oxide-free, without the cumbersome apparatus previously required for this purpose and without the previously created equipment. large heat losses. The same applies, of course, to all other oxidizing substances. With the appropriate selection of the influencing factors, the new process gives the possibility of being able to manufacture metals and metal alloys in particular stress-free and in some cases corrosion-free.



  Since the influence of the currents only has to take place for a short time, it is evident that this process also results in a considerable acceleration in production and thus a considerable reduction in the required quantities in circulation.
