抄録

A package of computer programs which can calculate fluid flow, induced current, argon gas fraction in molten steel, and meniscus shape was developed and applied to the numerical study on the effect of EMBR. In the numerical analysis of the fluid flow, BFC (Body Fitted Coordinate) was implemented into FVM (Finite Volume Method) to consider complex geometry of the SEN (Submerged Entry Nozzle) and irregular shape of the meniscus.<br> In investigation about the influence of important operating parameters on the effect of EMBR, several useful standards like the followings were used as evaluation standards: average velocity beneath the meniscus, the shape of the meniscus, and the standard deviation of velocities of each grid plane along the casting direction. In spite of general stabilizing effect of EMBR, it was found that the molten steel stream spouted from the SEN makes bypasses to avoid strong magnetic field region under particular conditions: such bypasses act as channels and prevent uniform distribution of the flow. A mechanism and conditions for the formation of them were suggested in the discussion.
