Abstract
Molten steel contained in a solidified steel skin of a continuously cast steel strand, is inductively stirred by inductive stirrers supplied with multi-phase AC having a frequency of from about 2 Hz to about 3 Hz, thereby obtaining an increased field strength or flux density in the molten steel and reducing the currents induced wastefully in the skin of solidified steel.
