Abstract
A steel continuous casting method using a continuous caster that includes a pair of upper magnetic poles and a pair of lower magnetic poles is disclosed. The method comprises braking a molten steel flow with the DC magnetic fields respectively applied to the pair of upper magnetic poles and the pair of lower magnetic poles while stirring a molten steel with an AC magnetic field simultaneously applied to the pair of upper magnetic poles, the strength of an AC magnetic field applied to the upper magnetic poles is set within the range of 0.060 to 0.090 T and the strengths of DC magnetic fields applied to the upper and lower magnetic poles are controlled within particular ranges in accordance with the width of the slab to be cast and the casting speed.
