Title
(DE) VERFAHREN ZUR HERSTELLUNG EINES TREIBSPIEGELGESCHOSSES
(EN) METHOD FOR PRODUCING A SABOT-DRIVEN PROJECTILE
(FR) PROCÉDÉ DE FABRICATION D'UN PROJECTILE À SABOT
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung eines Treibspiegelgeschosses, wobei ein Rohteil (5) des Treibspiegelgeschosses, insbesondere ein Rohteil (5) eines Treibspiegels, durch ein Pressgussverfahren hergestellt wird, wobei eine Schmelze (2) in einer Gießform (1) erstarrt und so das Rohteil (5) gebildet wird. Das Verfahren ist dadurch verbessert, dass als Schmelze (2) eine Knetlegierung verwendet wird.
(EN)
The invention relates to a method for producing a sabot-driven projectile, wherein a blank (5) of the sabot-driven projectile, in particular a blank (5) of a sabot, is produced by means of a pressure-casting method, wherein a melt (2) solidifies in a casting mold (1), thus forming the blank (5). The method is improved in that a wrought alloy is used as a melt (2).
(FR)
L'invention concerne un procédé de fabrication d'un projectile à sabot, une ébauche (5) du projectile à sabot, en particulier une ébauche (5) d'un sabot, étant produite au moyen d'un procédé de coulée sous pression, une matière fondue (2) se solidifiant dans un moule de coulée (1), formant ainsi l'ébauche (5). Le procédé est amélioré en ce qu'un alliage corroyé est utilisé en tant que matière fondue (2).
