摘　　要：为了控制电磁铸造过程中液体金属液面的稳定性 ,借助于激光测量传感器研究低熔点伍德合金在 2 5 0 0Hz交变电磁场作用下液面波动情况及液面形状 ;通过实验发现 ,电磁场作用下沿液面半径方向各点的波动规律相似 ,当金属液面与感应线圈上平面平齐 ,并且施加适当功率的电磁场时 ,能获得更好的液面形状 ,并使液面波动更平缓。In order to control surface stability of molten metal during electromagnetic casting and continuous casting, surface behavior of wood alloy with low melting point, is studied by using of a laser gauging sensor under alternative magnetic field . It is found that motion behaviors of each point on molten metal surface under magnetic fild are almost the same, and the high surface stability could be obtained when molten metal level is located equally with upside of induction coil and suitable power is imposed.
