Description
Die Erfindung betrifft eine elektromagnetische Rühreinrichtung für eine Brammenstranggießkokille, wobei eine durch einen Tauchausguß in die Kokille eingeleitete Stahlschmelze durch elektromagnetische Spulen wahlweise mit unterschiedlichen elektromagnetischen Feldern beaufschlagt wird.The The invention relates to an electromagnetic stirring device for a slab casting mold, one introduced through a submerged nozzle in the mold Molten steel by electromagnetic coils optionally with different electromagnetic Fields is acted upon.
Bei einer derartigen durch die JP – A – 63 – 188461 bekannten Rühreinrichtung werden die elektromagnetsichen Spulen wahlweise mit Wechselstrom oder Gleichstrom beaufschlagt um ein elektromagnetisches Rühren oder Bremsen der Stahlschmelze zu bewirken und so die Qualität der gegossenen Bramme zu verbessern.at such by JP - A - 63 - 188461 known stirring device The electromagnetic coils are optionally with alternating current or DC energized by an electromagnetic stirring or Braking the molten steel and thus the quality of the cast Improve slab.
Durch die US – PS 3 153 820 ist eine elektromagnetische Rühreinrichtung bekannt, wobei zur Erzeugung von Rührkräften unterschiedlicher Intensität Elektromagnete kontinuierlich, aufeinanderfolgend, mit veränderlichen Frquenzen und/oder Phasenbeziehungen betrieben werden können. Auch diese Maßnahmen dienen der Qualitätsverbesserung.By the US PS 3,153,820, an electromagnetic stirring device is known, wherein for generating stirring forces of different Intensity electromagnets continuous, consecutive, with variable frequencies and / or Phase relationships can be operated. These measures too serve the quality improvement.

Aufgabe der Erfindung ist die Schaffung einer Rühreinrichtung der obigen Gattung mit gegenüber den bekannten Einrichtungen vielfältigerem Rührprogramm zur besseren Anpassung an unterschiedliche Stahlqualitäten und Betriebssituationen einer Stranggießanlage. Insbesondere soll beim Angießen und langsamen Gießen die Schmelzenverteilung verbessert und beim schnellen Gießen die innere Qualität gesteigert und der Badspiegel beruhigt werden.task The invention is to provide a stirrer of the above type with opposite the well-known facilities diverse Rührprogramm for better adaptation to different steel qualities and operating situations of a continuous casting plant. In particular, should when casting and slow casting improves the distribution of melt and during rapid casting the inner quality increased and the bathroom mirror to be calmed.
Die gestellte Aufgabe wird nach der Erfindung dadurch gelöst, dass die entlang der Breitseitenwände der Brammenkokille angeordneten elektromagnetischen Spulen in den Feldwirkungen beidseits der Kokillenmitte auf die Schmalseitenwände gerichtet, zur Kokillenmitte entgegengesetzt oder statisch mit Strom beaufschlagbar sind.The Asked object is achieved according to the invention in that along the broadside walls the slab mold arranged electromagnetic coils in the Field effects directed on both sides of the center of the mold on the narrow side walls, opposite to the center of the mold or statically charged with electricity are.
Dabei wird in Betriebsweise 1 eine Beschleunigung der Gießstrahlen und in den Betriebsweisen II und III ein Abbremsen der Gießstrahles um die stark turbulente Schmelze zu beruhigen erreicht.there becomes in operation 1 an acceleration of the pouring jets and in operations II and III, a deceleration of the pouring stream to calm down the highly turbulent melt.
Die Strombeaufschlagung der Rührspulen erfolgt vorteilhaft elektronisch gesteuert von einem Stranggießprozeßrechner.The Current is applied to the stirring coils Advantageously electronically controlled by a continuous casting process computer.
Mit Bezug auf die Zeichnung wird die Erfindung mit Merkmalen und Vorteilen erläutert.With Referring to the drawing, the invention with features and advantages explained.
