Abstract (en)

Vacuum die casting protective gas feed equipment, comprising a gas supply line (14) outside the casting chamber and-or suction box end facing the casting unit, is new. Protective gas feed equipment, for a vacuum die casting machine in which melt is dosed from a holding furnace through a suction pipe (6), comprises a gas supply line (14) arranged outside a casting chamber and/or suction box end region facing the casting unit.

Abstract (de)

Bei der Anwendung des Vakuum-Druckgießverfahrens werden hohe Anforderungen an die zu gießenden Werkstücke gestellt. Unerwünschte Einschlüsse, wie Verunreinigungen und insbesondere Oxide führen zu einer wesentlichen Qualitätsminderung. Damit eine Verbindung der Schmelze mit Luft vermieden wird, schlägt die Erfindung die Zufuhr von Antioxidationsgas derart vor, daß eine einfacher Anbau und ein geringer regeltechnischer Aufwand eine hohe Funktionssicherheit gewährleisten. <IMAGE>
