The results show that flow field in the mold can be effectively changed by electromagnetic field. With the increasing of magnetic flux density,the let stream intensity of molten steel from nozzle discharged is gradually reduced until its moved direction is changed, at the same time, the velocity rates of whole field is decreased. When the level magnetic field is used, the induced current of liquid metal in the mold is large eddy distribution in the whole flow zone.
