Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen von nahtlosen NE-Rohren, insbesondere von nahtlosem Kupferrohr aus einer stranggegossenen oder stranggepreßten Rohrluppe und dem anschließenden Walzen der Rohrluppe, insbesondere auf einem Planetenschrägwalzwerk, zu einem Rohr. Erfindungsgemäß wird die Rohrluppe (3) zur Ausbildung einer Kühlzone (K) in der einlaufenden Umformzone (U) des Walzwerks durch allseitig konzentrisch gerichtetes, intensives Besprühen mit Kühlmedien (15), vorzugsweise unter hohem Druck beaufschlagt und dabei eine solche Wärmemenge abgeführt, daß ein Temperaturanstieg des gewalzten Kupferrohres (4), insbesondere auf Rekristallisationstemperatur, zumindest teilweise unterdrückt wird.

Figure 00000001
The invention relates to a method for producing seamless non-ferrous tubes, in particular seamless copper tube from a continuously cast or extruded tube blank and the subsequent rolling of the tube blank, in particular on a planetary diagonal rolling mill, to form a tube. According to the invention, the tube blank (3) is formed to form a cooling zone (K) in the incoming forming zone (U) of the rolling mill by intensive, intensive spraying with cooling media (15) on all sides, preferably under high pressure, and in the process such an amount of heat is removed that a Temperature rise of the rolled copper tube (4), in particular to recrystallization temperature, is at least partially suppressed.
