Die Erfindung betrifft die Verwendung von durch Stranggie/i en erzeugten Hohlblöcken aus warmverformbaren Legierungen, wie beispielsweise Kupfer und Kupferlegierungen oder Aluminium und Aluminiumlegierungen zur direkten Herstellung von Fertigrohren durch Kaltverformen.The invention relates to the use of by continuous casting produced hollow blocks from thermoformable alloys, such as copper and copper alloys or aluminum and Aluminum alloys for the direct production of finished pipes by cold forming.

Es ist bisher üblich, Kupfer und Kupferlegierungen ebenso wie Aluminium und Aluminiumlegierungen, d.h. also warmverformbare Legierungen als Rundbarren in Kokillen oder nach dem Stranggießverfahren zu gießen. Anschließend werden die durch Stranggießen hergestellten Stränge in kurze Abschnitte zersägt und mittels einer Strang- oder Rohrpresse oder aber auch in einem Rohrwalzwerk zu einem Vorprodukt warmverformt. Dieses Vorprodukt wirdIt has hitherto been customary to use copper and copper alloys as well as aluminum and aluminum alloys, i.e. hot-deformable Alloys as round bars in permanent molds or using the continuous casting process to pour. Then the strands produced by continuous casting are sawn into short sections and using in an extrusion or pipe press or in a pipe rolling mill to form a preliminary product. This preliminary product will

wird anschließend durch Kaltverformen beispielsweise durch Ziehen oder Pilgern in mehr oder weniger vielen Kaltverarbeitungsstufen, gegebenenfalls unter Einschaltung von Entfestigungsglühbehandlungen zum Endquerschnitt gebracht. Als nachteilig hat sich hierbei erwiesen, daß nur begrenzte Rohrlängen hergestellt werden können, und zwar in Abhängigkeit von den in die Rohrpresse einsetzbaren Hohlblöcken.is then cold-formed, for example by drawing or pilgrimage in more or less many cold processing stages, brought to the final cross-section, if necessary with the inclusion of softening annealing treatments. As disadvantageous it has been found here that only limited pipe lengths can be produced, depending on the in the pipe press usable hollow blocks.

Durch die erfindungsgemässe direkte Verwendung stranggegossener Hohlblöcke zur Herstellung von Fertigrohren durch Kaltverformen, werden diese Nachteile beseitigt, da eine beliebige Unterteilung des gegossenen Hohlstranges erfolgen kann, wobei diese lediglich davon abhängig ist, in welcher Weise die Kaltverformung durchgeführt wird, d.h. durch Ziehen, Pilgern oder dergl. Hierbei werden aber - verglichen mit dem Stand der Technik - wesentlich größere Rohrlängen erzielt und dariiberhinaus ist vom wirtschaftlichen Gesichtspunkt gesehen, eine erhebliche Verringerung der Investitionen möglich, da auf Rohrpressen und dergl. verzichtet werden kann und darüberhinaus beim Lochen, wie es beim Stand der Technik notwendig war, Abfall entsteht, der erfindungsgemäß nicht anfällt.Due to the direct use according to the invention of continuously cast hollow blocks for the production of finished pipes by cold forming, these disadvantages are eliminated, since any subdivision of the cast hollow strand can be made, this only depends on the way in which the cold forming is carried out, i.e. by drawing, pilgrimage or the like. Here but - compared to the prior art - much longer pipe lengths are achieved and, moreover, it is more economical Seen from the point of view, a considerable reduction in investments is possible, since pipe presses and the like are dispensed with can be and, moreover, when punching, as was necessary in the prior art, waste arises, which according to the invention does not arise.
