用数值解析方法，计算了铸型在周期振动过程中，润滑剂流路内动压的分布和弯月面的形状；研究了当铸型外部施加高频交流磁场时，电磁压力对动压分布和弯月面形状的影响． 分别用数值计算和连铸模拟实验两种方法，探讨了施加与连铸铸型振动同步的电磁场消除铸坯表面缺陷的可能性．结果表明：电磁压力扩大了润滑剂流路的厚度，抑制了弯月面的变形． 在包含铸型最低位置的时间间隔内同步施加电磁场时，可以获得表面质量更优异的铸坯． 获得同等表面粗糙度的铸坯，需要的平均电流量按施加连续电磁场、间断电磁场、在期间Ｎ 内同步施加电磁场的顺序大幅度地减少．
The dynamic pressure distribution and the shape of meniscus in the lubricant flow path were calculated by numerical analysis. The effect of electromagnetic pressure on dynamic pressure distribution And the shape of the meniscus. The two methods of numerical calculation and continuous casting simulation are respectively used to discuss the possibility of eliminating the surface defects of slab by applying the electromagnetic field synchronized with the vibration of continuous casting mold. The results show that the electromagnetic pressure expands the thickness of the lubricant flow path and suppresses the deformation of the meniscus. When the electromagnetic field is applied synchronously in the time interval including the lowest position of the mold, a slab having a better surface quality can be obtained. The same average surface roughness of the slab, the average amount of current required by the application of continuous electromagnetic field, intermittent electromagnetic field, the application of electromagnetic fields within the synchronization N sequence significantly reduced.
