Abstract

Die Erfindung betrifft ein Verfahren zur Schmelztauchbeschichtung eines Me- tallstranges (1), insbesondere eines Stahlbandes, bei dem der Metallstrang (1) vertikal durch einen das geschmolzene Beschichtungsmetall (2) aufnehmenden Behälter (3) und durch einen vorgeschalteten Führungskanal (4) hindurchge- führt wird, wobei zum Zurückhalten des Beschichtungsmetalls (2) im Behälter (3) im Bereich des Führungskanals (4) ein elektromagnetisches Feld mittels mindestens zwei beiderseits des Metallstranges (1) angeordneter Induktoren (5) erzeugt wird und wobei zum Stabilisieren des Metallstranges (1) in einer mittigen Lage im Führungskanal (4) ein sich dem elektromagnetischen Feld der Induktoren (5) überlagerndes elektromagnetisches Feld mittels mindestens zwei beiderseits des Metallstranges (1) angeordneter Zusatzspulen (6) erzeugt wird. Zur Verbesserung der Effizienz der Regelung des Metallstranges im Führungskanal ist erfindungsgemäss vorgesehen, dass die Stabilisierung der mittigen Lage des Metallstranges (1) im Führungskanal (4) durch die Abfolge der folgenden Schritte in einem geschlossenen Regelkreis erfolgt: a) Messen der Lage (s, s', s') des Metallstrangs (1) im Führungskanal (4); b) Messen des Induktions stroms (IInd) in den Induktoren (5); c) Messen des Induktionsstroms (IKorr) in den Zusatzspulen (6); d) Einwirken auf den Induktionsstrom (IKorr) in den Zusatzspulen (6) in Abhängigkeit aller in den Schritten a) bis c) gemessenen Parameter (s, IInd, IKorr), um den Metallstrang (1) in einer mittigen Lage im Führungskanal (4) zu halten. Des weiteren betrifft die Erfindung eine Vorrichtung zur Schmelztauchbeschichtung eines Metallstranges.
