Abstract
At least two magnetic induction elements operated with alternating current are disposed successively in the longitudinal direction at the guide for a strand of a continuous casting plant, and in particular for a continuous steel casting plant, to provide a stirring mechanism. Each induction element is connected to its own phase (R, S, T, N) of the at least two phase alternating current and the phases (R, S, T, N) are shifted with respect to each other by a phase angle of from about 0 to 180 degrees. In order to avoid the formation of a continously uniformly directed circulating current of metal despite a simple and sturdy stirring provision and without the presence of additional switching circuits, the phases (R,S,T) generate in each case electromagnetic forces under formation of a magnetic alternating field at at least two neighboring induction elements, where the momentary value differences and the directional differences correspond to a phase shift of .PHI.+180 degrees.
