Description

Verfahren zur Herstellung von Dauerformen für Schleuderguß Es sind bereits Gußformen für Schleuderguß vorgeschlagen, deren Innenwandungen aus einem auswechselbaren Stahlrohr bestehen.Process for the production of permanent molds for centrifugal casting There are already proposed molds for centrifugal casting whose inner walls consist of a interchangeable steel tube.

Gemäß vorliegender Erfindung wird eine eiserne Dauerform mit einer Gußeisenschicht von geeigneter Stärke ausgegossen, und zwar im Schleudergußverfahren. Während des Ausgießens wird die Dauerform zweckmäßig erwärmt. Nach dem Ausgießen wird sie bis in die Nähe ihres ursprünglichen Durchmessers ausgebohrt. Es läßt sich so mit sehr geringem Kostenaufwand eine rasche Herstellung dauerhafter Schleudergußformen erzielen und die Erneuerung gebrauchter Schleudergußformen vornehmen.According to the present invention, an iron permanent form with a Cast iron layer of suitable thickness poured out using the centrifugal casting process. During the pouring, the permanent form is expediently heated. After pouring out it is drilled to near its original diameter. It can be thus a rapid production of permanent centrifugal casting molds at very low cost achieve and renew used centrifugal casting molds.
