<p>In a curved or arc-type continuous casting installation provided with a curved or arc-type rigid dummy bar the curved dummy bar is separated from the cast strand at the region of the straightener by means of a movable roller. To improve the economy and to increase the decoupling reliability the dummy bar head is provided with a permanent coupling member which is disengageable from the cast strand by performing a pivoting movement. Furthermore, the dummy bar head is pivotably connected or linked to the dummy bar so as to be pivotable about an axis extending transversely with respect to the strand moving direction. For disengagement of the dummy bar head from the cast strand the movable roller presses upon the pivotable dummy bar head so that the same, during the casting operation, is pivoted outwardly out of its axial position away from the curved longitudinal axis of the curved dummy bar.</p> |
