| Abstract: | Through coupling electromagnetic field
equations with turbulent flow equations, the numerical prediction has been conducted on the
flow field of molten steel and the trajectory of inclusion particle in the continuous casting mold
effected by electromagnetic field. The difference between the maximum and the minimum of the
shear stress on mold wall is used to scale the impingement strength of molten steel discharged
from immersed nozzle to the solidifying shell on the narrow wall of mold. The flow field of
molten steel in the mold is changed greatly and the impingement strength of the jet is reduced
while electromagnetic field is applied. It is found that the successful control of flow field
depends on the current and location of coil. At the same time, the new floating paths of inclusion
particles are formed and the upward particles that are far away from the solidifying zone on the
narrow wall of mold change their moving directions with the change of flow field, so that the
particles can avoid being entrapped by the solidifying shell. |
