Abstract
A process and apparatus for starting a continuous casting plant, which involves the filling of the empty area over the dummy bar of an ingot mold to the desired filling level, is simplified while achieving improved operating safety. To this end, a controllable spout closure, which is completely open during the starting of the casting of the molten metal into a tundish, is brought into a predetermined throttle position by the actual filling level rising in the ingot mold to a first signal level and thereafter the further rise of the actual filling level is monitored and controlled, if necessary, in accordance with a second signal level of a predetermined characteristic time curve by logically changing the throttle position of the spout closure. It is thereby possible to control the actual filling level rising in the ingot mold so as to reach its desired filling level without undue risk.
