借助于光纤摄像机观测了钢液的模拟物─—液体Ga和铸型之间的接触状态，研究了间断接触距离（表征接触状态的星）和磁场间断频率的依存关系，进行了间断磁场作用下液体金属共振运动的理论分析在分别加间断磁场和连续磁场的条件下，进行了Sn的连续铸造模拟实验当间断频率f1接近于实验系统的固有频率时，金属液产生共振运动使弯月面和铸型之间的间断接触距离增大，金属液缓冷却效果相对较好和连续磁场对比，间断磁场能更有效地抑制铸型振动引起的液面运动，在获得同等表面质量铸坯的情况下，可以节省电力50％－70％
By means of fiber optic camera, the simulation of molten steel - the contact state between liquid Ga and the mold was observed. The dependence of the discontinuous contact distance (the star characterizing the contact state) and the interrupting frequency of the magnetic field was studied, and under intermittent magnetic field Theoretical Analysis of Liquid Metal Resonance Motion Simulating experiment of continuous casting of Sn under the conditions of intermittent magnetic field and continuous magnetic field respectively. When the discontinuity frequency f1 is close to the natural frequency of the experimental system, the resonance of the liquid metal causes the meniscus and The intermittent contact distance between the mold increases, the metal cooling effect is relatively good slow and continuous magnetic field contrast, intermittent magnetic field can more effectively inhibit the mold vibration caused by the liquid surface movement, in the case of the same surface quality of slab , You can save electricity 50% -70%
