摘    要：以侧壁配备电磁搅拌系统的钢包精炼炉为背景,分别利用多普勒超声波测速仪以及激光液位仪对几种电磁搅拌方式下金属液的内部流动以及表面波动状况进行了测定及分析。研究发现,电磁搅拌可以有效促进金属液的内部流动以及表面波动,从而显著改善金属液内部的动力学条件,是提高钢包精炼效率的有效手段;不同电磁搅拌方式对金属液的内部动力学条件影响的差异明显,在不同的精炼工艺要求下,可以考虑采用不同的电磁搅拌方式。

Abstract: Against the background of actual ladle furnace with electromagnetic stirring system,the study measured and analyzed the level fluctuations and the internal speed distribution of liquid metal under different electromagnetic stirring types by using laser liquid level apparatus and Doppler ultrasound velocimetry respectively.The study showed that electromagnetic stirring can not only effectively increase the level fluctuations,but also effectively promoted the internal flow of liquid metal so as to significantly improve the kinetic condition of liquid metal.The effect of electromagnetic stirring on level fluctuations and internal speed of the liquid metal differs with electromagnetic stirring types.Different electromagnetic stirring types should be adopted to meet different technological requirements during refining process.
