Abstract

An dem Warmhaltetiegel ist eine angeformte Vorkammer (4), (4.1) vorgesehen, die so konstruiert ist, dass zwischen dem Tiegelinnenraum (12) und dem Vorkammerinnenraum (13) eine Verbindungsöffnung (8),(8.1) verbleibt, die das Prinzip der kommunizierenden Röhren erfüllt.
Das bei Bedarf einzubringende Flüssigmetall wird ausschliesslich über die angeformte Vorkammer (4),(4.1) eingebracht.
Der Metallspiegel im Tiegelinnenraum steigt ohne Wirbelung auf die gewünschte Höhe an.
Bei dem einzubringenden Flüssigmetall handelt es sich vornehmlich um Alu-Legierungen.
Alu-Legierungen neigen leicht dazu, Oxide inform von Oxidhäuten zu bilden, die dann in der Schmelze schweben und zu Ausschuß der Gussteile führen.
Die Einbringung des Flüssigmetalls über die Vorkammer reduziert die Oxidbildung sehr stark, da keine Metallaufwirbelung erfolgt.
Der durch Oxidhäute entstehende Ausschuss der Gussteile wird erheblich eingeschränkt.
