ABSTRACT In the automatic start of pouring process of a continuous casting installation, metal melt (11) is discharged in a controlled manner from a vessel (10) by means of a stopper valve (15) provided in it and a continuous casting mould (20), which is closed at the bottom by a starting head, is filled with the melt (11). During the filling the stopper (15) is moved a number of times in the opening and closing directions in program-controlled time intervals and differing opening and closing displacements (s1 to sn) associated with them. The stopper (15) is preferably moved during the first opening or the pair of first openings (92) approximately into the completely open position (P1) and its opening displacements (s3, s4, s5) are consequently reduced with increasing filling level (h). Pouring may be started extremely reliably and operationally securely with this very precise automatic start of pouring process. (Fig. 1)
