Description

Anwendung des Verbundschleudergießverfahrens auf die Herstellung von mechanisch hochbeanspruchten Hohlkörpern Es ist bereits vorgeschlagen worden, Verbundhoh,lkörper auf dem Wege des Schleudergießverfahrens herzustellen. Eine solche Anwendung dieses VerfaIrens verfolgt bisher ausschließlich den Zweck, ähnlich wie bei plattierten Blechen, den Hohlkörper mit einer gegen chemische Einflüsse widerstandsfähigen Schicht zu versehen, um auf diese Weise eine Ersparnis an hochwertigen Werkstoffeil zu erreichen.Application of the compound centrifugal casting process to the manufacture of mechanically highly stressed hollow bodies It has already been proposed that Verbundhoh, lkörper to be produced by centrifugal casting. One such application of this VerfaIrens has so far only pursued the purpose, similar to plated Sheet metal, the hollow body with a layer resistant to chemical influences to be provided in order to achieve a saving in high-quality material part in this way.

Es ist ferner bekannt, hochbeanspruchte Hohlkörper aus mehreren Lagen zu bilden. Es sind Geschützrohre in der Weise hergestellt worden, daß man z. B. Seelenrohre in Mantelrohre einsetzt, um den hohen Verschleißwiderstan,d des Seelenrohres mit der hohen Zähigkeit des Mantelrohres zu vereinigen, Zum Erreichen der hohen Güteeigenschadten des Geschutzrohres war es bisher erforderlich, -das Seelen- und Mantel.rohr getrennt für sich herzustellen, einzeln zu bearbeiten und sorgfältig ineinander einzupassen. Ein solches Herstellungsverfahren erfordert jedoch ein, 'hohes Maß an Arbeitsaufwand und besonders geschulte Arbeitskräfte. It is also known to form highly stressed hollow bodies from several layers. There gun barrels have been manufactured in such a way that one z. B. core tubes are used in casing pipes to combine the high wear resistance, d of the core pipe with the high toughness of the casing pipe to edit and to fit carefully into each other. However, such a manufacturing process requires a 'high level of labor and specially trained workers.

Zur wesentlichen Vereinfachung der Anfertigung von mechanisch hochbeanspruchten H,6hIikörperii, insbesondere Geschützrohren, wird er:findungsgemäß vorgeschlagen, das bei der Herstellung von Verbundhohl:körpern an sich bekannte Schleudergießverfahren anzuwenden, in der Weise, daß die verschiedenen Lagen des Hohlkärpers aufeinander aufgebracht werden.To significantly simplify the production of mechanically highly stressed H, 6hIikkörperii, especially gun barrels, it is: proposed according to the invention, the centrifugal casting process known per se in the manufacture of composite hollow bodies to apply in such a way that the various layers of the hollow body are applied to one another will.

Durch das Herstellungsverfähren im Sinn, der Erfindung ergibt sieh eine erhebliche Einsparung an Rohrstal-4 und mechanischer Bearbeitung sowie eine innige metallische Verbindung zwischen den verschiedenen Lagen. Auch ist es möglich, nach dem gleichen Verfahren beliebig viel, Lagen von Metallen jeder gewünschten Zusajmmensetzung und Stärke aufeinander aufzubringen, so. daß alle Anforderungen hinsichtlich der Vereinigung von verschleißfesten Stählen mit solchen hoher Zähigkeit und Dehnung erfüllt werden können.By the manufacturing process in the sense of the invention, see a considerable saving in Rohrstal-4 and mechanical processing as well as a intimate metallic connection between the different layers. It is also possible Any number of layers of metals as desired using the same process To apply composition and strength to each other, like that. that all requirements regarding the union of wear-resistant steels with such high toughness and elongation can be met.
