Abstract: Continuously from part I, three dimensional distributions of magnetic field in soft-contacting electromagnetic continuous casting (EMCC) mold are systematically investigated numerically. Influences of structural parameters such as slit length/width, number of slit and wall thickness of mold, and the operating parameters such as free surface heights of liquid steel, electrical current densities, on magnetic flux density in mold were investigated separately. The max magnetic induction increases from 0.056T to 0.071T when slit length goes up to 220 mm from 130 mm; and increases from 0.058T to 0.089T when slit width goes up to 1.1 mm from 0.3 mm. The magnetic induction increases remarkably when the number of slit increases from 8 to 32, and the increase trend becomes smooth after 32. The max magnetic induction decreases about 50% when the mold wall thickness increases from 10 mm to 19 mm. The free surface of liquid steel should locate at the center position of inductor coil to obtain the largest magnetic induction. The max magnetic induction increases linearly against electrical density.
