Description

Verfahren zur Herstellung nahtloser Rohre Es ist bereits vorgeschlagen worden, nahtlose Rohre aus einem Hohlkörper durch Auswalzen auf einer Block-, Vor- und Fertigstraße herzustellen, wobei zwischen die Vor-und Fertigstraße ein Reduzierwalzwerk eingeschaltet ist, in welchem die von der Vorstraße kommende Luppe im Durchmesser reduziert wird. Dadurch soll an der Fertigstraße eine große Anzahl von Kalibern erspart werden.Method of making seamless pipes It has already been proposed been, seamless tubes from a hollow body by rolling on a block, pre and manufacture finishing train, with a reducing mill between the roughing and finishing train is switched on, in which the billet coming from the roughing train has a diameter is reduced. As a result, a large number of gauges should be produced on the finishing mill be saved.

Demgegenüber unterscheidet sich das Verfahren gemäß der Erfindung grundsätzlich dadurch, daß man den dickwandigen Hohlkörper in einem Lochwalzwerk auf dünne Wand bringt, die Luppe alsdann z. B. in einem Reduzierwalzwerk auf den gewünschten Durchmesser reduziert und dann in einem Duowalzwerk auf fertige Wand auswalzt, Dadurch wird nicht nur das Herstellungsverfahren an sich verkürzt und vereinfacht. sondern auch der Aufbau der ganzen Anlage zur Ausübung des Verfahrens. An Stelle des Block- und Vorwalzgerüsts tritt das Lochwalzwerk, es wird also ein Aggregat erspart. Ein Wiederanwärmen des Werkstückes vor dem Fertigwalzen im Duowalzwerk ist nicht erforderlich, «Teil das Werkstück wesentlich wärmer aus dem Lochwalzwerk herauskommt als aus dem Vorwalzgerüst.In contrast, the method according to the invention differs basically by the fact that the thick-walled hollow body in a piercing mill brings on thin wall, then z. B. in a reducing mill on the desired diameter and then in a duo rolling mill on the finished wall Rolls out, This not only shortens the manufacturing process itself and simplified. but also the construction of the entire system for carrying out the procedure. The piercing mill takes the place of the ingot and roughing stand, so it becomes one Saves aggregate. Reheating of the workpiece before finish rolling in the duo rolling mill is not necessary, «part of the workpiece is much warmer from the piercing mill comes out than from the roughing stand.

PATENTANSPRUCH: Verfahren zur Herstellung nahtloser Rohre, dadurch gekennzeichnet, daß man einen dickwandigen Hohlkörper zunächst in einem Lochwalzwerk auf verhältnismäßig dünne Wand bringt, hierauf das Werkstück in einem Reduzierwalzwerk auf den gewünschten Durchmesser reduziert und dann in einem Duowalzwerk auf fertige Wand auswalzt. PATENT CLAIM: A method for producing seamless tubes, characterized in that a thick-walled hollow body is first placed on a relatively thin wall in a piercing mill, then the workpiece is reduced to the desired diameter in a reducing mill and then rolled out to the finished wall in a duo rolling mill.
