采用ProCast商业软件根据实际生产的工艺参数建立了高碳钢77B连铸坯凝固传热的数学模型，并进行了相应的射钉实验进行验证。结果表明，射钉处坯壳厚度匹配较好，该模型能够较好地预测其凝固传热行为；拉速对不同位置处的坯壳厚度影响较为明显，过热度的影响则十分有限；拉速控制在1.6 m/min左右，有利于控制电磁搅拌区域内合理的液芯直径，从而改善铸坯的内部质量。

A mathematical model was established to investigate the solidification and heat transfer for 77B steel billet based on the practical process using Procast package, which was validated by comparing the shell thickness achieved by the nail shooting experiment. The results show that the thickness of shell matched well between the results of the two models, and the numerical model could successfully predict the solidification and heat transfer; the casting speed apparently outweighed the casting temperature to decide the thickness of shell. It is well-advised to keep the casting speed at 1.6 m/min to improve the performance of F-EMS.
