摘　　要：凝固末端位置对于凝固末端电磁搅拌位置的确定至关重要。根据实际情况建立了方坯连铸凝固传热数学模型,并通过射钉法对模型进行了检验。结果表明该模型能够较好地预测凝固末端位置并为凝固末端电磁搅拌提供指导。The position of final solidifying point of the continuous casting billet is very important for determination of F-EMS. In the present paper, a mathematical model to describe the solidification process of continuous casting billet is established according to the actual conditions of steelworks, and the model is validated by the measured data obtained by pin-shooting of billet. The results show that the present model can predict the position of final solidifying point and provide reasonable data for F-EMS.
