| 摘 要： | 结合方坯连铸机二冷各段的实际情况,采用有限元软件ANSYS建立了传热数学模型,并利用射钉结果修正数学模型中各段的传热系数,提高数学模型的准确性.结果表明,利用修正过的数学模型可以模拟整个铸机的传热凝固过程.根据射钉和数值模拟结果,确定电磁搅拌位置.采用电磁搅拌后,铸坯中心碳偏析和缩孔下降.

| Abstract: | In combination with the actual situation of the secondary cooling of a billet continuous caster,a heat-transfer mathematical model was established with finite element software ANSYS.Heat-transfer coefficients in different secondary cooling regions were modified on the basis of pin-shooting results to improve the accuracy of the mathematical model.The results show that the modified mathematical model can simulate the whole heat-transfer and solidification process of the continuous caster.The location of elec... |
