摘　　要：随着薄板坯无头轧制技术和高效连铸的发展,高拉速连铸带来的漏斗形铜板裂纹问题日益严重。研究者们利用理论分析、工业试验和数值模拟方法对薄板坯漏斗形铜板裂纹形成机制和控制进行研究,目的是延长铜板寿命,降低生产成本。阐述了漏斗形结晶器铜板裂纹的宏观形貌和危害,归纳了铜板裂纹形成的热疲劳机制、蠕变疲劳机制和元素侵蚀机制,详细总结了铜板热/力分析模型的发展,介绍了铜板裂纹控制措施,提出了铜板裂纹形成机制、热/力分析模型和控制的新研究方向。With the advancements in thin slab direct rolling and efficient continuous casting,the issue of funnelshaped cracks in copper molds resulting from high-speed casting has become increasingly severe.Researchers had explored the formation mechanism and control of these cracks in thin slab casting by means of theoretical analysis,industrial experiments and numerical simulation methods,aiming to prolong the lifespan of copper molds and reduce production costs.The macroscopic morphology and hazards of funnel-shaped copper mold cracks were elucidated,and the mechanisms of crack formation,including thermal fatigue,creep fatigue,and elemental erosion,were summarized.A comprehensive review of the development of thermal/mechanical analysis models for copper molds was provided,along with an overview of measures for controlling copper mold cracks,new research directions were proposed for the mechanism of copper mold crack formation,thermal/mechanical analysis models,and control strategies.
