Abstract
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.
