Description

Verfahren zur Herstellung von nahtlosen Rohren Die Erfindung betrifft ein Verfahren zur Herstellung von nahtlosen Rohren aus Puddel- oder Schweißstahl, der stets erhebliche Mengen Schlacke enthält.Method of Making Seamless Tubes The invention relates to a process for the production of seamless pipes from puddle or welded steel, which always contains significant amounts of slag.

Für nahtlose Rohre aus Schweißstahl bestand wegen der größeren Korrosionsbeständigkeit des schlackenhaltigen Schweißstahls immer eine große Nachfrage. Es ist auch schon bekannt geworden, solche Rohre durch Walzen o. dgl. herzustellen. Die Herstellung war aber mit großen Schwierigkeiten verknüpft, und es kann zweifelhaft sein, ob überhaupt brauchbare Ergebnisse erzielt wurden.For seamless tubes made of welded steel existed because of the greater corrosion resistance of the weld steel containing slag is always in great demand. It's also beautiful it has become known to produce such tubes by rolling or the like. The production but it was fraught with great difficulties, and it can be doubted whether any useful results have been achieved.

Es wurde nun die überraschende Beobachtung gemacht, daß lange nahtlose Rohre aus Puddel- oder Schweißstahl in glatter Weise durch das bekannte Warmspritzen auf den bekannten, mechanisch angetriebenen Strangpressen aus dem vollen Block hergestellt werden können. Dieses Ergebnis konnte nicht vorausgesehen werden, da man nicht wußte, wie sich die Schlacke beim Spritzen verhalten würde. Versucht man beispielsweise Gußeisen zu spritzen, so erhält man kein Rohr, sondern ein grobes Eisenpulver. Bei den bekannt gewordenen Verfahren zum Warmspritzen von Eisen und Stahl auf mechanisch angetriebenen Strangpressen ist nicht davon die Rede, daß auch der stark schlackenhaltige Puddel- oder Schweißstahl verpreßt werden könnte.The surprising observation has now been made that long seamless Pipes made of puddle or welded steel in a smooth manner by the well-known hot spraying Manufactured from the solid block on the known, mechanically driven extrusion presses can be. This result could not be foreseen because one did not know how the slag would behave when sprayed. If you try, for example Injecting cast iron does not produce a pipe, but a coarse iron powder. at the well-known method for hot spraying iron and steel on mechanical Driven extrusion presses are out of the question that also the highly slag-containing Puddle or welding steel could be pressed.
