Abstract

Verfahren zum gesteuerten Abschrecken von Leichtmetallgußstücken in einem Flüssigkeitsbad, bei dem die Gußstücke im Flüssigkeitsbad von unten zumindest zeitweise von einem aufsteigenden Gasblasenstrom angeströmt werden, wobei die Gasblasen des Gasblasenstroms am Grund des Flüssigkeitsbades gleichverteilt in situ erzeugt werden.

Figure 00000001
Method for the controlled quenching of Leichtmetallgußstücken in a liquid bath, in which the castings in the liquid bath from below are at least temporarily flowed by an ascending gas bubble stream, wherein the gas bubbles of the gas bubble stream are generated evenly distributed in situ at the bottom of the liquid bath.
