摘　　要：针对国内某厂６０ｔ中间包浇注低碳铝镇静钢的多次试验数据，从理论上建立了浇注过程中中间包钢水氧含量的预测模型。模型中综合考虑了钢包渣中ＦｅＯ及ＭｎＯ含量、耐火材料中ＳｉＯ２含量、钢包到中间包钢水吸氮量、浇注时间、拉速、铸坯断面积等因素的影响，并对改进中间包操作进行了讨论。According to experimental data of continuous casting , low carbon Al-killed steel in 60 t tundish ,a quantitative prediction model for oxygen content of steel in tundish is established. Some factors , such as FeO and MnO content in ladle slag , SiO2 content in the refractory of ladle and tundish lining , [N] pick up from ladle to tundish ,casting time ,tundish steel weight , casting speed etc. are considered in the model. Some proposal for improving tundish operation are presented in this paper.
