The distribution of the magnetic flux density in the magnetic field generator which provided travelling magnetic field was determined. The experiments using liquid gallium and aluminum - silicon alloy to observe the turbulent flow or remove inclusions were performed to obtain the basic principles how the distribution of the magnetic flux density took effect on removing inclusions from molten metal by electromagnetic field. The suitable area in the field for purifying metal was suggested. 相似文献

The temperature of the meniscus in continuous casting was measured during mold oscillation by modeling experiments,It is found that the temperature of meniscus varied periodically along with mold oscillation.Based on the above phenomenon.the mechanism of smoe techniques,such as ,hot top mold,high frequency and low amplitude mold oscillation,soft-contact mold electromagentic continuous casting and so on,which can improve the quality of continuous casting billets,was analyzed.The results show that the decrease of the temperature fluctuation of early solidification shell is their common mechanism. 相似文献
