摘要： 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.

摘要： For preventing break-out in a continuous casting plant in which the quantity of molten material being supplied to a mold is controlled to a predetermined level, changes in the quantity of molten material being supplied to the mold is constantly monitored. The time behavior of quantity increases of molten material being supplied to the mold is determined and a break-out signal is produced when the quantity of molten material increases at more than a predetermined rate. The break-out signal may be produced only when the rate of change of molten material in the mold and the rate of change of the speed of a casting leaving the mold are less than predetermined values.

摘要： The casting of several strands with a common puller unit is effected by a process which allows a high degree of operational reliability in its initial start-up phase. To accomplish this, slide gates or valves are throttled at a predetermined level provided in the lower area of a measuring section monitoring the levels in a group of molds and the strand-pulling drive is switched on and the slide gates of molds that have remained in the level below the level are closed no later than at a point when at least one of the actual levels in the molds is at another predetermined level which is below the optimum level. The rising of the levels in the molds may be controlled in accordance with preset rising curves.
