Abstract
A multi-phase stirrer for stirring the molten cores of cast slabs from continuous casting machines is divided into at least two partial stirrers with each partial stirrer comprising at least one phase winding and fed with a number of phases at least one less than the total number of phases of the stirrer apparatus. Each partial stirrer may be arranged at different sides of the cast slab to form a rotary field around the cast slab in association with the other partial stirrers. Additional iron cores may be arranged in the air gaps formed between the iron cores of the respective partial stirrers. Alternatively, the additional iron cores may be arranged within the support tubes of the casting apparatus.
