摘　　要：半连续铸造技术作为目前有色金属坯料的主要制备手段,决定着坯料的品质和尺寸,并对后续的加工和使役性能具有重要影响。然而,传统的半连续铸造技术制备的锭坯存在组织粗大和不均、开裂倾向大、偏析严重等问题。外加物理场是一种改善锭坯品质的有效方法。综述了外加物理场作用下半连续铸造技术的发展,系统讨论了各种物理场处理技术调控熔体和铸锭品质的机理、发展历史、研究进展和存在的问题。最后,展望了该技术未来的发展方向。As a main preparation method for non-ferrous light alloy billets at present,semi-continuous casting technol⁃ogy determines the quality and size of billets,which has a significant effect on subsequent processing and end-use per⁃formance.However,there exist problems in the billets prepared by traditional semi-continuous casting technology,such as coarse and uneven microstructure,high cracking tendency,and severe segregation.Application of external physical field is a highly effective method to improve the quality of billets.The development of semi-continuous casting technology under external physical fields was reviewed,and the mechanism,development history,research progress and existing problems of various physical field treatment techniques controlling the quality of melt and billet were sys⁃tematically discussed.Finally,the future development of the technology was prospected.
