| 摘 要： | 介绍了在铝铸轧工艺中用频率交替变化的电磁场抑制晶粒长大的方法，阐述了粘性流体与电磁波频率响应的关系，分析了电磁场频率与熔体波动对晶粒细化效果产生的影响。结果表明在d650mm×1600mm铸轧机系统中，电磁场的最佳频域范围为11～15Hz。

| Abstract: | The method of controlling velo city of grain growth in a luminum electromagnetically continuous cast-rolling by inputting rotated elect romagnetic field was introduced. The relationship between viscous fluid and frequency response was described. The ef fect of electromagnetic field frequency and melt fluctuation on grain refinement was analyzed. The best frequency band 11～15 Hz under norm al condition (d650 mm×1 600 mm roller) was obtained. |
