A molten steel is electromagnetically stirred in at least two of three locations, viz. a casting mold and intermediate and final solidifying zones of a continuously cast strand. In the casting mold, is applied a magnetic field induced by alternate current of a frequency f=1.5 ~ 10 Hz and having G in the range of 195 x e-0.18f ~ 1790 x e-0.2f at the inner surface of the casting mold.
