説明
In order to realize a higher performance of metal materials, further progress in the technology of electromagnetic stirring of liquid metal is needed, because traditional electromagnetic stirrers using rotating magnetic field (RMF) and traveling magnetic field (TMF) have several undesirable characters like severe surface deformation and weak mixing in RMF; violent surface fluctuation in TMF. In the present study, a new electromagnetic stirrer, a double axis electromagnetic stirrer (DAEMS), composed of RMF and TMF is proposed and its performance is investigated using liquid gallium. There are two modes of DAEMS, one is upward imposition of TMF and the other is downward. The former is found to give a much stronger turbulent mixing than RMF under same rotational speed, which seems advantageous to disperse CaO particles into liquid iron in the desulfurization process. The latter is found to achieve a flat and calm free surface under a rotational motion with stronger turbulent mixing than RMF. This character is thought to be advantageous to extend widely the limit of stirring due to deformation and fluctuation of free surface.
