摘　　要：在间歇式高频磁场作用下，通过高速数码摄像机观测并研究了熔融金属弯月面的形状及其波动行为，建立了保护渣浸入深度的理论计算模型．经与实验结果比较，计算值与实验值吻合，由此提出在钢的连铸过程中采用间歇式高频磁场代替结晶器机械振动的可能性．The behavior of the meniscus of molten metal and mold flux penetrating into a flux channel between the molten metal and the mold were visualized. A calculated model of penetration depth of the mold flux has been developed. It was found that the experimental results of penetration depth of the mold flux agree well with the calculated one. It is predicted that the function of mold oscillation can be substituted by imposition of an intermittent high frequency magnetic field in continuous casting of steel.
