Description

Schleudergußform mit galvanischem Überzug und Verfahren zu ihrer Herstellung Bei Schleudergußkokillen mit besonderen Seelenrohren aus Stahl ist es bekannt, das Seelenrohr mit einem galvanischen Überzug aus Chrom zu versehen, weil dieser Stoff gegen Korrosion und das flüssige Metall besonders widerstandsfähig ist. Solche Kokillen sind aber sehr teuer und haben den Nachteil, daß sie die Hitze des Gußstückes zu langsam ableiten. Man kann deshalb in einer bestimmten Zeit nur wenige Gußstücke gießen, und das Seelenrohr wird außerdem sehr stärk und sehr lange heiß und daher rasch unbrauchbar.Electroplated centrifugal casting mold and process for making it In centrifugal casting molds with special steel core tubes, it is known that To provide the core tube with a galvanic coating of chrome, because this substance is particularly resistant to corrosion and the liquid metal. Such molds but are very expensive and have the disadvantage that they take the heat of the casting too slowly derive. You can therefore only make a few castings in a given time pour, and the soul pipe also becomes very strong and very long hot and therefore quickly unusable.

Nach vorliegender Erfindung wird dagegen die Brauchbarkeit und Lebensdauer der Gußform dadurch gesteigert, daß die Innenfläche einer gewöhnlichen, unmittelbar in die Kühlflüssigkeit tauchenden Kokille ohne Seelenrohr mit Silber, Kupfer, Aluminium oder einem ähnlichen wärmeleitfähigen Metall galvanisch überzogen wird. Solche Formen leiten die Hitze des Gußstückes sehr rasch ab und können deshalb in einer bestimmten Zeit eine wesentlich größere Anzahl von Güssen liefern. Außerdem sind sie auch länger brauchbar und daher nicht nur in der Herstellung, sondern auch im Gebrauche erheblich billiger. Mit besonderem Vorteil wird der galvanische Niederschlag so stark gemacht, daß er sich bearbeiten und also genau maßhaltig herstellen läßt. Kupfer kann verhältnismäßig rasch in starker Schicht niedergeschlagen werden und eignet sich deshalb besonders gut zum Überziehen von Kokillen, welche wegen zu großer Lichtweite besonders starke Überzüge erhalten sollen.According to the present invention, on the other hand, the usability and service life become the mold increased by the fact that the inner surface of an ordinary, immediate Mold immersed in the coolant without a core tube with silver, copper, aluminum or a similar thermally conductive metal is electroplated. Such forms dissipate the heat of the casting very quickly and can therefore in a certain Time to deliver a significantly larger number of casts. They are also longer useful and therefore significant not only in production but also in use cheaper. With particular advantage, the galvanic precipitation is made so strong that that it can be machined and thus produced precisely true to size. Copper can be proportionate can be quickly precipitated in a thick layer and is therefore particularly suitable good for covering chill molds, which are particularly strong because they are too large Should receive coatings.
