ABSTRACT:
A method of establishing a turbulent motion of molten steel within a strand guide of a continuous casting plant for casting a steel strand, wherein at least one group of three electromagnetic induction coils are arranged adjacent the strand guide, two of the induction elements being arranged consecutively in the longitudinal direction of the guide. At least two of the induction elements are offset relative to each other, transverse to the longitudinal direction of the strand guide, and the three induction elements form the corner points of an imaginary triangle having no more than one side lying in a plane extending parallel or perpendicular to the longitudinal direction of the strand guide. The imaginary triangle extends across the width of the strand. One phase of a three phase AC current is connected to each electromagnetic induction element. One of the induction elements has its input terminals electrically reversed with respect to the other two elements. When power is applied to the induction elements, a discontinuous electromagnetic AC field is established within the imaginary triangle extending across the width of the strand, wherein the electromotive forces produced by the induction elements produce travelling waves in several directions to cause a turbulent motion and an effective mingling of the melt within the strand over the total width of its liquid core.
