Abstract (en)
1. A method for the continuous casting of steel, wherein molten metal is poured into a mould, and the resultant strand, having a liquid core, is with-drawn and guided and supported in a guide path, and turbulent flow is induced in the liquid core by at least two electromagnetic travelling fields, characterized in that simultaneously acting thrust forces of different magnitudes are produced by these travelling fields so that the flows caused by these thrust forces mutually influence each other.
Abstract (de)
Zur Verbesserung der Kristallstruktur und zur Verminderung der Nachteile von positiven und negativen Seigerungen beim Stranggiessen von Stahl wird mit Hilfe von mindestens zwei Wanderfeldern unterschiedliche Schubkräfte auf den flüssigen Stahl erzeugt, wobei sich die entstehenden turbulenten Strömungen gegenseitig beeinflussen.
