   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 
 EMI1.3 
   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. 
 EMI1.4 
 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
 EMI1.3
   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.

PATENT-ANSPRUCH : Verfahren zur gleichzeitigen Herstellung von mehreren nahtlosen Metallröhron durch Walzen oder Ziehen von ineinander liegenden Metall-Hohlkörpern, dadurch gekennzeichnet, dass diese Hohlkörper, nachdem sie innen und aussen mit einem sie gegen Anfressen oder Zusammenschweissen schützenden, dünnen Anstrich, z. B. aus Kalkmilch oder einer Mischung von Graphit und Kohle überzogen worden sind, passend, ohne Zwischenkerne, ineinander gesteckt, und alle miteinander auf einem dem Walz- oder Ziehvergang widerstehenden Grnndkern im Walzwerk, auf der Ziehbank oder auf der Ziehpresse bearbeitet werden. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the simultaneous production of several seamless metal tubes by rolling or drawing of nested metal hollow bodies, characterized in that these hollow bodies, after they have been coated inside and outside with a thin coating protecting them against pitting or welding together, e.g. B. have been coated with milk of lime or a mixture of graphite and carbon, fittingly, without intermediate cores, plugged into one another, and all of them are processed together on a core core resisting the rolling or drawing process in the rolling mill, on the draw bench or on the drawing press. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
