To get the fundamental characteristics of magnetohydrodynamics is extremely important because in-mold electromagnetic stirring is required to get high quality steel. We have researched magnetohydrodynamic calculations to estimate the experimental data. At first, we compared the calculation velocity and measurement velocity in a pot mold. There is good agreement, though the calculation data depend upon the procedure after flow dynamic calculation. Next, we compared molten metals such as molten steel, mercury and fused metal. Since molten steel provides difficulties for measurements, we often estimate the magnetohydrodynamic characteristics through measurement data from mercury or fused metal. The calculation data show that molten steel has the highest speed, though the fused metal has the lowest speed. Lastly, we compare the fluid dynamic characteristics between a pot mold and an endless mold. Though an endless mold is already used in practice, the experimental mold is a pot one. After we get measurement data from the pot mold, we must estimate the characteristics of the endless mold. The calculated data show that the velocity of the pot mold near the meniscus level is larger than that of the endless mold, because the endless mold has the turned over flow from the fixed bottom in the pot mold.
