Abstract: The effect of decarburization process, deoxidizing, alloying, blowing oxygen and adding aluminium and non-operating factors on liquid temperature during RH-MFB refining process is analyzed and studied, and a prediction model for refining liquid is established. Verifying results by continuous-refining 10 heats 270 t ultra-low carbon liquid (0.001% ~0.002 5%C) temperature show that the error of liquid temperature calculated by model and measured is no more than ±5 ℃.

摘要： 分析研究了RH-MFB精炼时脱碳过程、脱氧、合金化、吹氧加铝、非操作因素对钢水温度的影响,并建立了精炼钢水温度预报模型。通过对连续精炼的10炉270 t超低碳钢水(0.001%~0.0025%C)温度的验证结果表明,模型计算温度和实测温度的误差不大于±5℃。
