The primary object of the present invention is to provide a method for continuously casting steel which further suppresses pinhole defects. The present invention is a method for continuously casting steel wherein, in a case where: an average value of Lorentz force density components in a direction parallel to a long side of a mold 11 within existence of an iron core 13a is Lx (N/m 3 ), the iron core being a component of an electromagnetic stirrer 13; and an average value of Lorentz force density components in a direction parallel to a short side of the mold 11 within existence of the iron core 13a is Ly (N/m 3 ), a relationship between effective Lorentz force density F (N/m 3 ) that is calculated by F = Lx - ±·Ly, and current frequency (Hz) of the electromagnetic stirrer 13 is obtained, and current frequency of the electromagnetic stirrer 13 within the range of a maximum value Fmax to 0.9 Fmax of the effective Lorentz force density F is used. |
