Abstract

Bei dem Verfahren zur Verbindung von Stahlrohren mit Aluminiumrippen wird zunächst auf die Oberflächen der Stahlrohre oder der Aluminiumrippen eine Schicht aus einer Zink-Aluminium-Legierung mit einem Aluminiumbestandteil von 0,5% bis 20% aufgebracht und dann vor dem oder beim mechanischen Kontakt der Aluminiumrippen mit den Stahlrohren zwischen die Stahlrohre und die Aluminiumrippen bei Raumtemperatur ein Flussmittel in Form von Cäsium-Aluminium-Tetrafluorid eingebracht. Danach werden die mit den Aluminiumrippen versehenen Stahlrohre in einem Ofen auf eine Verlötungstemperatur zwischen 370 °C und 470 °C erwärmt und letztlich zur Abkühlung der Raumtemperatur ausgesetzt. Alternativ hierzu kann zunächst auf die Oberflächen der Stahlrohre oder der Aluminiumrippen eine Schicht aus einer Zink-Aluminium-Legierung mit einem Aluminiumbestandteil von 0-5% bis 20% aufgebracht und dann bei Raumtemperatur ein Flussmittel in Form von Cäsium-Aluminium-Tetrafluorid mindestens in den Berührungszonen auf die Aluminiumrippen gebracht werden. Danach werden die Aluminiumrippen mit den auf eine Löttemperatur zwischen 370 °C und 470 °C erwärmten Stahlrohren in mechanischen Kontakt gebracht und letztlich zur Abkühlung der Raumtemperatur ausgesetzt.
