Abstract (en)

[origin: EP0444297A2] In a method for starting up automatically a continuous casting installation, molten metal (11) is poured out of a vessel (10) in a controlled manner by means of a plug (15) provided in the said vessel and a continuous casting mould (20) closed off at the bottom by a dummy bar head is filled with the molten metal (11). During filling, the plug (15) is opened and closed several times at programme-controlled time intervals and with different opening and closing travels (s1 to sn) assigned to these time intervals. During the first or the first few opening(s) (s2), the plug (15) is preferably moved approximately into the fully open position (P1) and its opening travels (s3,s4,s5) are consequently reduced as the filling level (h) increases. With this very precise automatic start-up method, starting up can be performed with an extremely high degree of reliability and operational safety. <IMAGE>
