摘　　要：结合电磁场作用下连铸保护渣的发展状况,综述了电磁场作用下保护渣的熔化行为（包括熔化温度、熔化速度、熔化均匀性）、流变行为（包括黏度、黏温曲线、转折温度）、结晶行为（包括结晶矿相、结晶尺寸及结晶率）等变化规律,并基于此分析了电磁场下保护渣熔渣结构与各行为变化的关系,最后提出了存在问题及今后有待进一步完善的研究内容和方向,为系统研究电磁场作用下保护渣的冶金特性和进一步的理论研究提供借鉴。Development status of continuous casting mold flux under the action of electromagnetic field. The variation of melting behavior（including melting temperature,melting rate,and melting uniformity）,rheological behavior（including viscosity,viscosity temperature curve,transition temperature）and crystallization behavior（including crystalline ore phase,crystal size and crystallization rate）of protective slag under electromagnetic field is reviewed. Based on this analysis,the relationship between the slag structure and the behavior changes under the electromagnetic field is analyzed. Finally,the existing research questions and directions for further improvement are proposed. It provides a reference for the systematic study of the metallurgical properties of the protective slag under the action of electromagnetic fields and further theoretical research.
