Cu-2.0Fe-0.03P-0.11Zn alloy is a promising candidate material for electrical connectors owing to the low cost and excellent castability. Continuous casting serves as a key process in strip and plate production, where the solidification microstructure strongly influences subsequent processing and final product properties. In this study, a cellular automaton-finite element (CAFE) model was developed to simulate the solidification microstructure evolution of the Cu-2.0Fe-0.03P-0.11Zn alloy under continuous casting conditions. Simulated fractions of columnar and equiaxed grains were 87.4% and 12.6%, respectively, which were in close agreement with those of experimentally measured macrostructures (88.6% and 11.4%), confirming reliability and accuracy of the established model. Further investigations were conducted on effects of nucleation undercooling and nucleation density on solidification microstructure. Results indicated that increasing nucleation undercooling reduced the proportion of equiaxed grains: as undercooling increased from 1 K to 6 K, equiaxed grain fraction decreased from 17.1% to 9.2%, respectively. In contrast, increasing nucleation density promoted equiaxed grain formation, with equiaxed grain fraction increasing from 10.4% to 18.5% as the nucleation density increased from 0.5×10⁹ m^–3 to 40×10⁹ m^–3, respectively.

Cu-2.0Fe-0.03P-0.11Zn合金因成本低廉且具有良好的加工性能，是制造电连接器的优选材料。连续铸造作为该合金板带制备过程中的关键工序，其凝固组织对材料加工过程和最终产品性能具有显著影响。本文采用元胞自动机-有限元耦合模型（CAFE）法，对Cu-2.0Fe-0.03P-0.11Zn合金在连续铸造条件下的凝固组织演化进行了数值模拟。结果显示，模拟得到的柱状晶与等轴晶比例分别为87.4%和12.6%，与低倍组织实测结果（柱状晶比例88.6%、等轴晶比例11.4%）在晶粒类型、分布区域及形貌特征方面高度一致，验证了所构建模型的可靠性与准确性。在此基础上，研究了形核过冷度与形核密度对凝固组织的影响。结果表明：形核过冷度升高会导致等轴晶区比例降低，当形核过冷度从1 K提升至6 K时，等轴晶区面积占比由17.1%下降至9.2%；而形核密度的增加有利于等轴晶区比例的提高，随着形核密度由0.5×10⁹ m⁻³增大到40×10⁹ m⁻³，等轴晶区比例由10.4%上升至18.5%。
