Abstract

Bei einem Verfahren zur Herstellung von stranggegossenen Gußstücken (7') wird entweder der Strang (7) oder das von ihm abgetrennte Gußstück (7') im heißen Zustand, u.zw. mit der noch vom Stranggießen herrührenden Hitze, zur Entfernung von Oberflächenfehlern (23 bis 28) und/oder oberflächennahen Fehlem spanabhebend bearbeitet.In a process for the production of continuously cast castings (7 ') either the strand (7) or the casting (7 ') separated from it in the hot state, etc. with the heat from continuous casting to remove surface defects (23 to 28) and / or defects close to the surface machined.

Um eine Entfernung der Fehler (22 bis 28) ohne eine Verwendung eines Fehlersuchgerätes und ohne die spanabhebende Bearbeitung der Gesamtoberfläche des Gußstückes bzw. des Stranges durchführen zu können, wird die spanabhebende Bearbeitung aufgrund von für das Stranggießen wichtigen Prozeßparametern aktiviert und deaktiviert (Fig.1).

Figure 00000001
In order to be able to remove the defects (22 to 28) without using a troubleshooting device and without machining the entire surface of the casting or the strand, the machining is activated and deactivated on the basis of process parameters important for the continuous casting (FIG. 1 ).
