ABSTRACT:
For the automatic casting start-up of a strand in continuous casting installations, a programmed start-of-casting curve is started with a slightly throttled sliding gate valve and each partial real time of the rising actual metal level is compared with the corresponding partial characteristic time during time ranges stored for each of the partial characteristic times wherein each of the individual ranges corresponding to a flow position of the valve, and the flow position of the time range into which the measured partial real time falls is set automatically. In this way, a preassigned start-of-casting curve can be optimally reproduced.
