摘　　要：在连铸生产过程中,特别在高拉速条件下,采用电磁控流技术可有效控制结晶器内钢液湍流流动行为,提高铸坯质量和连铸效率。根据磁场布置方式不同,将电磁制动控流装置分为区域型、全幅型和多模型三大类型,讨论各类电磁制动装置的布置方式及控流效果,总结其在实际应用中的优缺点,并对未来电磁控流技术的发展方向进行了展望。研究表明,不同磁场排列方式展现了电磁制动技术未来巨大的应用潜力,未来可以在保持流量控制效果基础上简化电磁制动系统,进一步建立涉及多物理场的综合模型,从而更准确地预测结晶器内钢液流动的真实情况。In the process of continuous casting,especially under the condition of high speed,the electromagnetic flow control technology can effectively control the turbulent flow behavior of the molten steel in the mold,improve the quality of the billet and the efficiency of continuous casting.In this paper,according to the different magnetic field layout,electromagnetic brake flow control devices are divided into three types:local type,ruler type and multi-mode type.By discussing the layout and flow control effect of various electromagnetic brake devices,the advantages and disadvantages of their practical applications are summarized,and the future development direction of electromagnetic flow control technology is prospected.Research has shown that different magnetic field arrangements demonstrate the enormous potential for future applications of electromagnetic braking technology.In the future,the electromagnetic braking system can be simplified while maintaining flow control effects,and a comprehensive model involving multiple physical fields can be further established to more accurately predict the true flow of molten steel in the crystallizer.
