Abstract
A teeming spout has on its inside a plurality of picket-like metal segments (1) separated from one another by slots (2) and is externally surrounded by an induction coil (3). The bottom turn (7) of this induction coil (3) has a downwardly directed pitch equalization piece (8) which provides such that the field acts uniformly on the teeming stream from all sides and therefore it is not deflected.
