摘要
根据实际生产的工艺参数,通过ProCAST商业软件对45#钢连铸坯的坯壳厚度以及凝固过程进行数值模拟,并进行现场射钉实验对模拟结果验证。结果表明,数值模拟与射钉实验所得结果在射钉处坯壳厚度差值较小,数值模拟相对于现场二级模型更能有效地显示出铸坯不同位置坯壳厚度,为末端电磁搅拌提供有效的参考。
According to the actual production process parameters,a mathematical model built by ProCAST was established to investigate the solidification and the thickness of shell for 45# steel in billet and a series of nail shooting experiments were carried out to test the model.After comparing with the shell thickness achieved by the nail shooting experiment,the results of mathematical model was more accurate to reflect the shell thickness than two-level model.The results show that the thickness of shell matches well between the results of the nail shooting experiment and the model.The numerical model could successfully predict the solidification process,which can provide effective reference for F-EMS.
