Description

Werkstoff für Kokillen zur Herstellung von Schleudergußrohren Bei der Benutzung von Schleudergußkokillen aus Guß@eisen hat man bisher mit wechselndem Erfolge gearbeitet; aber keine Ergebnisse erzielt, welche die Verwendung von Gußeisen für die Herstellung von Schleudergußkokillen für Rohre wirtschaftlich erscheinen lassen.Material for molds for the production of centrifugally cast pipes Bei the use of centrifugal casting molds made of cast iron has been changed so far Successes worked; but no results obtained with the use of cast iron appear economical for the production of centrifugal casting molds for pipes permit.

Nach der Erfindung sollen gußeiserne Kokillen für Schleudergußrohre mit Wolfram legiert werden. Hierdurch ergeben sich eine erhebliche Erhöhung der Festigkeit und insbesondere ein sehr feines Korn und dichter Guß sowie große Zähigkeit. Es ergibt sich also besonders gute Homogenität der Kokillen, so daß gerade das vermieden wird, was erfahrungsgemäß zu raschen Zerstörungen von Gußkokillen besonders beiträgt, nämlich Stel-. len von uriganzer Beschaffenheit und geringerer Festigkeit und Zähigkeit. Das Wolf, ram kann in der Pfanne zugesetzt werden. Mit etwa 3 % Wolfram läßt sich feinstes Korn und große Zähigkeit erzielen.According to the invention, cast-iron molds for centrifugally cast pipes are to be used be alloyed with tungsten. This results in a considerable increase in Strength and especially a very fine grain and dense cast as well as great toughness. This results in particularly good homogeneity of the molds, so that precisely that is avoided becomes, which experience has shown particularly contributes to the rapid destruction of casting molds, namely st-. oils of a rustic nature and less firmness and toughness. The wolf, ram can be added in the pan. With about 3% tungsten can Achieve the finest grain and great toughness.
