摘　　要：为研究适于6号连铸机的凝固传热模型,通过实际生产数据对相关参数进行修正,并通过低碳焊丝钢铸坯白亮带、液芯宽度、空冷段铸坯表面温度进行分析研究,验证了准确性。并且对拉速、过热度以及比水量进行计算分析,得出它们对铸坯表面温度、液芯末端位置的影响程度。结果表明,采用符合特定连铸机的凝固传热模型,并利用模型对生产工艺进行了探讨,可以提高铸坯内部质量。In order to develop the solidification heat transfer model suitable for No.6 continuous casting caster,the relevant parameters were modified by the actual production data,and the accuracy was verified by the analysis and research of the white band,liquid core width and surface temperature of the casting billet in the air cooling section of low carbon wire steel casting billet.The casting speed,superheat and specific water were calculated and analyzed,and the influence degree of them on the surface temperature of the billet and the position of the end of the liquid core was obtained.The results show that the internal quality of billet can be improved by using the solidification heat transfer model in line with the specific continuous caster and using the model to discuss the production process.
