Österreichische PATENTSCHRIFT Nr. 10445.
EMI1.1
fahren zur gleichzeitigen Herstellung von mehreren nahtlosen Metallröhren durch
Walzen oder Ziehen.
Angemeldet am 10. Februar 1902. - Beginn der Patentdauer: 1. September 1902.
Bis jetzt wurde bei den meisten Verfahren zur Herstellung von nahtlosen Röhren und anderen Hohlkörpern jedes einzelne Rohr aus einem Metallhloek für sich ausgewalzt oder gezogen. Wenn es sich dabei um Rohre von grosser Länge und dünner Wand handelte,
EMI1.2
Wandstärke erzielte.
Um nun diesen zeitraubenden und kostspieligen Arbeitsvorgang zu umgehen, werden nach der vorliegenden Erfindung mehrere nach dem Walz-oder Ziehverfahren die Röhren

worfen. Hierbei ist besonders hervorzuhol) en, dass diese Hohlkörper passend, ohne Zwischenkerne, ineinandergesteckt werden, so dass gleichsam ein innerer Hohlkörper dem nächst äusseren als Kern dient.

oder kaltem zusatnade in einem Kaliberwalzwerk auspgewalzt oder auf einer Ziehbank oder einer Ziepresse ausgezogen zu werden. Dadruch werden sämtliche Hohlkörper auf einmal auf die gewünschte Länge und Dicke gewalzt bezw. gezogen, und es dient jedesmal der kleinere Hohlkörper dem nächstgrösseren als Kern.
Nach beendigtem Walz-oder Ziehverfahren können die so gleichzeitig erhaltenen Rohre voneinander abgezogen werden, wobei der schützende Anstrich das Abziehen erleichtert. Die Wandstärken und Durchmesser der Rohre sind begreiflicherweise durch jene der rohen, unbearbeiteten Hohlkörper bestimmt.

Austrian PATENT LETTER No. 10445.
EMI1.1
drive through for the simultaneous production of several seamless metal tubes
Rolling or pulling.
Registered on February 10, 1902. - Patent period begins on September 1, 1902.
Up until now, most processes for the manufacture of seamless tubes and other hollow bodies have rolled or drawn each individual tube out of a metal rod. If these were pipes of great length and thin walls,
EMI1.2
Wall thickness achieved.
In order to avoid this time-consuming and costly operation, according to the present invention, several tubes are made by the rolling or drawing process

threw. It is particularly important to note that these hollow bodies are fitted into one another in a suitable manner, without intermediate cores, so that, as it were, an inner hollow body serves as the core of the next outer one.
EMI1.4
or cold additional rolled in a pass mill or drawn out on a drawing bench or a drawing press. Dadruch all hollow bodies are rolled BEZW at once to the desired length and thickness. drawn, and each time the smaller hollow body serves as the core of the next larger one.
After the rolling or drawing process has ended, the pipes thus obtained at the same time can be peeled off from one another, the protective coating facilitating the pulling off. The wall thickness and diameter of the tubes are understandably determined by those of the raw, unprocessed hollow bodies.
