| 摘 要： | 根据300t钢包RH真空处理超低碳铝镇静钢的实验数据,建立了RH处理过程钢中总氧含量的预测模型,得到了钢中氧含量的预测公式.模型综合考虑了处理时间、真空室吹氩流量、钢水环流量、浸渍管直径和钢包渣中(FeO+MnO)含量等因素对总氧含量的影响,并对改进RH处理工艺进行了讨论.模型分析表明,促进夹杂物上浮的手段有增大吹氩流量、增加浸渍管直径,但都有一个合适的范围.

| Abstract: | Based on the experimental data of ultra-low carbon aluminum killed steel in a 300 t ladle of RH treatment, a model for predicting the total quantitatively oxygen content of molten steel was established. Some factors such as treatment time, argon flow rate, molten steel circulation rate, snorkel diameter, FeO and MnO content in ladle slag were considered in the model. Potential improvements for RH operation were discussed. According to model analysis, the methods for promoting inclusion rising are increasing the argon flow and enlarging the snorkel diameter, but they have proper ranges. |
