- 摘要:
- 电磁净化技术是利用金属熔体与非金属夹杂物导电率不同，所受电磁力不一致的原理来实现夹杂物去除
的一种新型金属熔体净化技术。 本文介绍了金属熔体电磁净化技术在国内外的发展现状，主要对传统金属熔体净化方
法、金属熔体内常见夹杂物种类与特征、电磁净化原理、电磁净化技术类别以及电磁净化效率影响因素等 5 个方面进行
了综合分析与对比。 最后，对金属熔体电磁净化技术的未来研究方向提出自己的见解。
Electromagnetic separation technology is a new molten metal purification technology, which is based on the unequal electromagnetic forces exerted on the molten metal and non-metallic inclusions in electromagnetic field due to the difference of their electric conductivities. This paper introduced the state of the art of the electromagnetic separation technology at home and abroad, making a comprehensive analysis and comparison regarding to the traditional molten metal separation technology, the types and features of the common inclusions in molten metals, the principle and classification of the electromagnetic separation technology and the factors affecting the separation efficiency. The future development directions of the electromagnetic separation technology were proposed in the end
