Description

Verfahren zur Erneuerung gebrauchter, durch geeignete Bearbeitung verengter Kokillen für Schleudergußrohre Es ist bekannt, gebrauchte Kokillen für Schleudergußrohre durch mechanische Behandlung zu verengen.Process for the renewal of used, through suitable processing narrowed molds for centrifugally cast pipes It is known, used molds for Constrict centrifugally cast pipes by mechanical treatment.

Die Erfindung hat den Zweck, hochwertiges Kokillenmaterial möglichst lange benutzen zu können, und besteht darin, daß die verengten Kokillen zum Ausgleich der verlorenen ZVandstärke auf der Außenseite galvanisch überzogen werden, worauf sie wieder in der üblichen 'Weise auf Maß bearbeitet werden. Das Verfahren kann mehrmals wiederholt werden. Dabei wandert das wertvolle Material der ursprünglichen Kokille von außen nach innen, während neues Material auf galvanischem Wege von außen gewissermaßen wieder nachwächst. Für das Verfahren eignen sich besonders Kokillen aus Kupfer und Elektrolytkupfer. Das Verengen kann durch Ziehen, Schmieden, Pressen, Walzen, Recken bewirkt werden.The invention has the purpose of producing high quality mold material as possible to be able to use for a long time, and consists in the fact that the narrowed molds to compensate the lost wall thickness are galvanically coated on the outside, whereupon they are machined to size again in the usual 'way. The procedure can repeated several times. In the process, the valuable material of the original migrates Mold from the outside in, while new material galvanically from the outside to a certain extent grows back again. Molds are particularly suitable for the process made of copper and electrolytic copper. The narrowing can be done by drawing, forging, pressing, Rolling, stretching are effected.

PATENTANSPRÜCHE: i. Verfahren zur Erneuerung gebrauchter, durch geeignete Bearbeitung verengter Kokillen für Schleudergußrohre, dadurch gekennzeichnet, daß die Kokillen zum Ausgleich der verminderten Wandstärke auf der Außenseite einen galvanischen Überzug erhalten und darauf nötigenfalls in bekannter Weise auf Maß bearbeitet werden. PATENT CLAIMS: i. Process for the renewal of used, by suitable processing narrowed molds for centrifugal cast pipes, characterized in that the molds receive a galvanic coating on the outside to compensate for the reduced wall thickness and are then, if necessary, machined to size in a known manner. 2. Verfahren nach Anspruch i, dadurch gekennzeichnet, daß das Aufbringen des galvanischen Niederschlages so lange wiederholt wird, bis der ursprüngliche Kokillenwerkstoff aufgebraucht ist.2. The method according to claim i, characterized in that the Application of the galvanic deposit is repeated until the original Mold material is used up.
