| 摘要: |
| 超重力作为一种外场强化新技术,基于其优越的传质和相际分离特性,引起了广泛的关注。本文着重介绍了我国超重力技术在金属熔体提纯、冶金固废中有价物质的富集提取分离、金属材料凝固组织细化、非金属夹杂物的去除以及矿石气基还原等冶金和金属材料领域的研究进展和成果,提出了其应用过程中存在的科学问题,并展望了超重力技术的发展前景。虽然,目前还以实验室研究阶段为主,并未实现普适化。但作为一种外场强化新技术,其在冶金和金属材料凝固控制等相关研究体系中已突显出强大的熔体提纯、有价组分富集提取、组织细化、夹杂物去除等作用效果,这为进一步拓展超重力技术在冶金和金属材料领域的研究和开发应用提供了参考价值。超重力有望凭借自身的优点成为冶金和金属材料领域生产过程中一种新的外场技术。随着超重力设备的发展及相关科学问题的研究探索,相信在不久的将来,超重力技术必会在冶金和金属材料研究领域得到广阔的应用前景。 |

| Abstract: |
| As a new outfield strengthening technology, super gravity has attracted extensive attention, because of its powerful characteristics of mass transfer and phase separation. In this paper, the research progress and results of super gravity technology in metallurgy and metal material field were introduced, such as the metal purification, enrichment and separation of valuable material in metallurgy solid waste, microstructure refinement, nonmetallic inclusion removal, gaseous-reduction and so on. The existing scientific problems were put forward and the development prospect of super gravity was prospected. Yet it is still in the laboratory research stage, and the universalization has not been realized. However, as a new outfield field strengthening technology, it has shown great potential and effect in metal purification, enrichment of valuable component, microstructure refinement, inclusion removal, and so on. thus providing a reference to further expand the research and development application of super gravity technology in metallurgy and metal material field. Super gravity is expected to be a new technical means in metallurgy and metal material production with its own advantages. With the development of super gravity equipment and the exploration of related scientific issues, it is believed that the super gravity technology will be widely applied in metallurgy and metal material research field in the near future. |
