Abstract：The pulse magnetic field (PMF) can effectively refine metal grains of solidification, and is gradually in stage of industrializing application. It is prone to generating macro-segregation, loose of solidification problems for the Si steel, ferritic stainless steel, high speed steel and nickel alloy. So applying the PMF is put forward in continuous casting. The PMF is applied to the foot roller section, two cold sections and the solidification end of the continuous casting, and the critical magnetic flux density is respectively 0.0845 T, 0.122 T and 0.182 T. With shell thickness increasing of PMF applied position, the critical magnetic flux density increases, and adjusting the duty cycle can reduce the critical magnetic induction.
