摘要
A package of computer programs, which can be used to calculate magnetic fields, induced current, meniscus shape, and fluid flow was developed and applied to the numerical study of effect of hybrid magnetic fields mold. In investigation about the influence of important operating parameters on the effect of hybrid magnetic fields mold, three standards like the followings were used: the flow pattern, the maximum velocity beneath the meniscus, and the dynamic pressure on the contact point. It was found that the hybrid magnetic fields mold has the effects of both EMBR (Electromagnetic Brake) and soft contact EMC (Electromagnetic continuous casting) at the same time. On the other hand, the hybrid magnetic fields mold can overcome some shortcomings of EMBR and soft contact EMC with proper magnitudes of static magnetic flux density and suitable relative position of the two magnetic fields.
