Der Arbeitsablauf mit dem Rohrwalzwerk gestaltet sich wie folgt Eine ausgewalzte Rohrluppe wird von dem Längsförderer 19 auf der Dornstange 11 ge- ίο halten. Sie wird mit dem Längsförderer aus dem Schrägwalzgerüstl nach links in Fig. 1 herausgefahren. Gleichzeitig wird das Dornwiderlager 13 mit der daran befindlichen Dornstange 11 in die gestrichelte Position 14 gefahren. Damit hat die Dornstange 11 mit dem nicht abgeworfenen Dom (Stopfen) 9 ebenfalls das Schrägwalzgerüst 1 verlassen. Die Kupplung rüst ein neuer öiock zum τ, «■«* Γ^"°- 15 wird geöfmtt. Rohrluppe und Dornstange U wer- neue Walzvorgang kann unverzüglich beginnenThe work sequence with the pipe rolling mill is as follows. A rolled out pipe billet is held on the mandrel bar 11 by the longitudinal conveyor 19. It is moved out of the skewing stand to the left in FIG. 1 with the longitudinal conveyor. At the same time, the mandrel abutment 13 with the mandrel rod 11 located thereon is moved into the position 14 shown in broken lines. The mandrel bar 11 with the dome (plug) 9 that has not been thrown off has thus also left the cross-rolling stand 1. The coupling sets up a new lock to τ, «■« * Γ ^ "° - 15 is opened. Tube blank and mandrel bar U are the new rolling process can begin immediately
