| Abstract |
| Numerical analyses of fluid flow, heat transfer, solidification and inclusion transport in a steel slab caster under the application of static magnetic field were carried out. The effects of magnetic flux density and casting speed on distributions of fluid velocity and inclusion concentration were studied. At low casting speed and high magnetic flux density, the inclusion removal rate is found to be high due to the low inclusion penetration depth. With the increase of inclusion size and the decrease of casting speed, the effect of magnetic field on inclusion removal increases. The position of peak inclusion concentration in the fully solidified slab moves toward the top side of slab with the increase of inclusion diameter. The high magnetic flux density results in a low value of peak inclusion concentration. The inclusions of flotation velocity in the rage of 0.05∼0.36 times the casting speed show the highest peak in inclusion concentration. |
