Wie wir alle wissen, werden Eisenbahnschienen in bestimmten L\u00e4ngen hergestellt, wie z. B. 12,5 m, 25 m, und die l\u00e4ngeren von 50 m bis 100 m. Unabh\u00e4ngig davon, wie lang die Schienen sind, m\u00fcssen sie Ende an Ende miteinander verbunden werden, um ein durchgehendes Gleis zu bilden. Dies kann durch Schienenst\u00f6\u00dfe oder Schwei\u00dfverfahren erfolgen. In diesem Moment konzentrieren wir uns auf das Schwei\u00dfen von Eisenbahnschienen.\u00a0<\/span><\/p><\/div>

Es gibt vier g\u00e4ngige Methoden zum Schwei\u00dfen\u00a0Bahnschienen<\/a>. Sie sind das Abbrennstumpfschwei\u00dfen, das Gasdruckschwei\u00dfen, das Lichtbogenschwei\u00dfen und das Thermit-Schwei\u00dfen. Was sind die Unterschiede zwischen diesen Verfahren? Wir haben die Anwendungen unter verschiedenen Konstruktionsbedingungen f\u00fcr Ihren Vergleich zusammengefasst.<\/p>

Kurz gesagt, das Thermit-Schwei\u00dfen ist die am weitesten verbreitete Methode zum Schwei\u00dfen von Eisenbahnschienen. Es ist einfach zu bedienen und ben\u00f6tigt keine elektrische Energie. Die ben\u00f6tigten Ger\u00e4te und Materialien sind leicht zu beschaffen.\u00a0<\/p>

Das Prinzip des Thermit-Schwei\u00dfens bei der Eisenbahn<\/h2>

Das Thermit-Schwei\u00dfen von Eisenbahnschienen ist ein Schwei\u00dfverfahren, bei dem die W\u00e4rme einer chemischen Reaktion als W\u00e4rmequelle genutzt wird. Beim Schwei\u00dfen werden die Enden der beiden Schienen im Voraus in der Form fixiert, und dann wird die Mischung aus Aluminiumpulver und Eisenoxidpulver (Thermit genannt) im Tiegel erhitzt. Durch eine exotherme Reaktion entstehen fl\u00fcssiges Metall (Eisen) und geschmolzene Schlacke, die in die Form gespritzt werden. Das fl\u00fcssige Metall flie\u00dft in die Fugenspalte und bildet das Schwei\u00dfgut, w\u00e4hrend die Schlacke an der Oberfl\u00e4che schwimmt. Um die Temperatur der Schmelze und die chemische Zusammensetzung des Schwei\u00dfguts zu regulieren, werden dem Thermit h\u00e4ufig geeignete Zusatzstoffe und Legierungen zugesetzt.<\/p>

\u00a0<\/p>

  1. Vorbereitung<\/span><\/li><\/ol>

    Vorbereitung der Ger\u00e4te und Hilfsmittel<\/span>
    Verbrauchsmaterial: Thermit, Sandform, Schmelztiegel, Dichtungsschlamm, Hochtemperaturstreichh\u00f6lzer, Schleifscheibe, Propan, Sauerstoff, Schlauch.
    Hilfsmittel: Form, Schlackenwanne, Tiegelgabel, Sandformvorrichtung, Sandformabdeckung, 1 m Schr\u00e4glineal, Schienenthermometer, Spannvorrichtung, Brechstange, Vorheizrahmen, Stahlkeil.
    Hilfsmaschinen: Schienens\u00e4ge, Poliermaschine, tragbare Schleifmaschine, usw.<\/p>

    Vorbereitung der Gleise<\/span>
    Entladen Sie die 2-4 Paare von\u00a0Schienenbefestigungen<\/a>\u00a0auf beiden Seiten des Schwei\u00dfendes.<\/p>

    \"ausr\u00fcstung-zum-schwei\u00dfen-der-schienen-schienen\"<\/figure><\/div>
    1. Reinigung und Trocknung der Schienenenden<\/span>
      Verwenden Sie die\u00a0      tragbare Schleifmaschine<\/a>\u00a0um Rost zu entfernen und das Schienenende zu dekontaminieren. Stellen Sie sicher, dass die Oberfl\u00e4che der zu schwei\u00dfenden Schienenenden trocken und sauber ist.<\/li>
    2. Ausrichtung der Schienenenden<\/span>
      Die Breite zwischen den Schienenstirnseiten muss 27 mm bis 30 m betragen. Die vertikale und horizontale Ausrichtung von Schienenkopf, Schienensteg und Schienenfu\u00df ist erforderlich.<\/li>
    3. Installation der Vorrichtungen<\/span>
      Die Leuchte sollte in Windrichtung installiert werden.<\/li>
    4. Einbau von Sandformen<\/span>
      Die Gie\u00df\u00f6ffnung ist leicht beschnitten, um zu verhindern, dass beim Vorw\u00e4rmen und Gie\u00dfen Sandpartikel abfallen und Schwei\u00dfschlacke entsteht.
      Bringen Sie zuerst die Bodenplatte an, dann die Seitenform und schlie\u00dflich die Klammer, um die Sandform zu befestigen.<\/li>
    5. Versiegeln<\/span>
      Tragen Sie Dichtungsmasse auf den Auslass der Sandform und das Gewinde der Halterung auf, um die Sandform und die Schiene dicht abzuschlie\u00dfen.<\/li>
    6. Vorheizen<\/span>
      Erstens: Stellen Sie den Arbeitsdruck von Propan und Sauerstoff ein. Zweitens: Installieren Sie das Heizger\u00e4t auf dem Rahmen, stellen Sie die D\u00fcse auf die Mitte der Sandform ein und platzieren Sie den Nebenschlussstopfen auf dem Rand der Sandform, entfernen Sie das Heizger\u00e4t von der Halterung und z\u00fcnden Sie die D\u00fcse. Drittens: Stellen Sie den Druck und das Mischungsverh\u00e4ltnis von Propan und Sauerstoff ein, um die beste Flamme zu erhalten. Zum Schluss heizen Sie 5 Minuten lang vor.<\/li>
    7. Schmelztiegel-Installation<\/span>
      Dieser Schritt wird zur gleichen Zeit wie das Vorheizen vorbereitet. Mischen Sie das Thermit gleichm\u00e4\u00dfig und gie\u00dfen Sie es in den Schmelztiegel. Setzen Sie das Hochtemperatur-Streichholz ein und decken Sie den Tiegel ab.<\/li>
    8. Z\u00fcndung<\/span>
      Legen Sie den Tiegel gleich nach dem Vorheizen auf die Sandform. \u00dcberpr\u00fcfen Sie die Position und z\u00fcnden Sie das Streichholz schnell an.<\/li>
    9. Thermit-Reaktion<\/span>
      Beobachten Sie die chemische Reaktion. Wenn eine offene Flamme auftritt, beginnt die Thermitreaktion. Sobald die Flamme erloschen ist, ist die chemische Reaktion beendet. Normalerweise dauert die Thermit-Reaktion 8-15 Sekunden.<\/li>
    10. Entschalung<\/span>
      Entfernen Sie die Sandform und die Schlackenwanne 5 Minuten nach dem Gie\u00dfen des geschmolzenen Eisens.<\/li>
    11. \u00dcbersch\u00fcssiges Thermit abschneiden<\/span>
      Schneiden Sie das \u00fcberfl\u00fcssige Thermit ab und biegen Sie die \u00fcberstehenden Teile auf beiden Seiten der Schienenbasis.<\/li>
    12. Schleifen<\/span>
      Dies ist der letzte Schritt beim Schwei\u00dfen von Eisenbahnschienen. Dadurch wird die Oberfl\u00e4che der verbundenen Schienen flach und glatt.<\/li><\/ol>

      Pr\u00fcfen Sie nach Abschluss der 13 Arbeitsschritte die Schwei\u00dfn\u00e4hte, um sicherzustellen, dass sie den Anforderungen entsprechen. Bringen Sie die Gleise an ihren urspr\u00fcnglichen Platz zur\u00fcck. Au\u00dferdem sind noch einige Aufr\u00e4umarbeiten zu erledigen. Die Arbeiter m\u00fcssen den Staub, die Schlacke, den Schrott, die Sandform und den Schmelztiegel entfernen.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
