Description

Verfahren zum Innen-Emaillieren von Röhren. Mit dem bisher bekannten Verfahren zum. Innen-Emaillieren von Röhren konnte man nur Rohre von ,größeren Durchmessern und kleineren Längen emaillieren. Das lag daran, daß es bislang nicht möglich war, die Rohre während des Emaillierens fortlaufend zu drehen und den Ofen fortlaufend zu beschicken und ebenso zu entleeren. Das Emaillieren konnte nur in einzelnen Chargen erfolgen.Process for internal enamelling of tubes. With the previously known Procedure for. Internal enameling of tubes was only possible for tubes with larger diameters and enamel smaller lengths. That was because it was not previously possible to rotate the tubes continuously while enamelling and the furnace continuously to be charged and also to be emptied. Enamelling was only possible in individual batches take place.

Das Neue und Wesentliche der vorliegenden Erfindung beruht demnach einmal darin, daß die in den Ofen eingelegten Rohre fortlaufend gedreht werden, was dadurch erreicht wird, daß die Ofenplatte eine zur Horizontalen geneigte Bahn erhält, auf der die Rohre langsam und stetig herabroll?n und so die Emaillierzone langsam durchwandern. Das erwähnte Rollen ist erforderlich, damit aufgetragene bzw. eingespritzte Emaille, die bei langen und dünnen Rohren nur in ungleichmäßiger Stärke eingebracht werden kann, sich nicht im unteren Teil des Rohres ansammelt und dort beim Erkalten festsetzt.The novelty and essence of the present invention resides accordingly once in that the pipes placed in the furnace are continuously rotated, which is achieved in that the furnace plate has a path inclined to the horizontal on which the tubes slowly and steadily roll down and so the enamelling zone wander slowly through. The above-mentioned rolling is necessary so that the applied resp. injected enamel, which is only unevenly thick in the case of long and thin tubes can be introduced, does not accumulate in the lower part of the pipe and there sets on cooling.

Die weitere Neuerung besteht darin, daß der Ofen fortlaufend beschickt und entleert wird.Another innovation is that the furnace is continuously charged and is emptied.

Die bislang bekannten Emaillierverfahren gestatteten nur, daß man den Ofen auf einmal beschickte, schloß und ,nach Fertigstellung der Emaille denselben wieder entleerte, um von neuem eine Charge vornehmen zu können.The enamelling processes known up to now only allowed that one loaded the furnace at once, closed it and, after the enamel was finished, closed it again emptied in order to be able to carry out a new batch.

Beim neuen Verfahren werden die Rohre an der Stelle i eingeführt, um nach dem Durchrollen des Ofens an der Stelle 2 fertig entnommen zu werden. Inzwischen sind neue Rohre an der Stelle i eingeführt, so daß der ganze Vorgang des Innen-Emaillierens ein fortlaufender ist.In the new method, the pipes are inserted at point i, to be removed at point 2 after rolling through the oven. In the meantime new pipes are introduced at point i, so that the whole process of internal enamelling is a continuous one.

Die fortlaufende und gleichmäßige Bewegung im Ofen wird durch eine automatisch betätigte, wassergekühlte Mitnehmerwalze 3 erzielt.The continuous and even movement in the oven is ensured by a automatically operated, water-cooled driver roller 3 achieved.

Die Walze hat Riefen, eine solche nimmt das ihr zurollende Rohr auf und führt es mit vorher bestimmter Geschwindigkeit zur Abfallstelle, auf diese Weise den nachdrängenden Rohren die Geschwindigkeit lind somit die vorgeschriebene Dauer des Innen-Emaillierens aufzwingend. An der Abfallstelle fallen die Rohre, die bereits hinreichend .durch die wassergekühlte Walze abgekühlt wurden, in eine Mulde, wo sie noch Reiter abgekühlt dem Ofen entnommen werden.The roller has grooves, one of which picks up the pipe that is rolling towards it and leads it to the waste place at a predetermined speed, in this way The speed of the following pipes is therefore the prescribed duration of internal enamelling. At the waste point, the pipes that already fall were cooled sufficiently .by the water-cooled roller, in a trough where they can be removed from the oven while still rider has cooled.

Die Abbildung stellt sonst im Schnitt einen Glühofen bekannter Ausführung mit Feuerung. Feuerzügen und Isoliergewölbe dar.The illustration shows an annealing furnace of known design in section with firing. Fire trains and insulating vaults.
