照）。On the other hand, as a method of overcoming the drawbacks of the prior known technologies, an electromagnet was installed in the mold of the continuous slab caster and a magnetic field perpendicular to the molten steel discharge jet from the immersion nozzle was applied to it. Then, the molten steel flow is damped by the Lorentz force generated by the interaction between the current and the magnetic field induced in the molten steel, and the discharge jet is suppressed from penetrating deeply into the molten steel pool, whereby the entrainment of the mold powder is caused. There has been proposed a method of preventing the occurrence of pits and promoting the floating of inclusions brought into the molten steel. (J.Na
