Abstract

Bei einem Verfahren zum Regeln der Füllstandshöhe in Stranggießkokillen (10, 10′) einer Mehrfachstranggießanlage mit mindestens zwei von einem gemeinsamen Verteilerge­ fäß (12) versorgten Stranggießkokillen, aus denen Stränge (16, 17) mittels eines Synchronantriebes (18, 24) ausgezogen werden, werden durch Beobachtung des Schmelzenbadspie­ gels (23) in einer der Stranggießkokillen (10) Abweichungen des Niveaus des Schmelzenbadspiegels (23) in dieser Stranggießkokille (10) von einem Sollwert unter Verände­ rung der Ausziehgeschwindigkeit sämtlicher der aus den Stranggießkokillen (10, 10′) austretenden Gußstränge (16, 17) kompensiert, wogegen Abweichungen des Niveaus des Schmelzenbadspiegels (14) in der (den) weiteren Stranggießkokille(n) (10′) durch Veränderung der Schmel­ zenzulaufmenge in der (den) weiteren Stranggießkokille(n) (10) geregelt werden. In a method for regulating the level in Continuous casting molds (10, 10 ') of a multiple continuous casting plant with at least two from a common distribution ge barrel (12) supplied continuous casting molds, from which strands (16, 17) pulled out by means of a synchronous drive (18, 24) by observing the melt pool gels (23) in one of the continuous casting molds (10) deviations the level of the melt pool level (23) in this Continuous casting mold (10) from a setpoint under changes the extraction speed of all of the Continuous casting molds (10, 10 ′) emerging casting strands (16, 17) compensated, whereas deviations in the level of the Melt bath level (14) in the further one (s) Continuous casting mold (s) (10 ′) by changing the melt flow rate in the other continuous casting mold (s) (10) can be regulated.
