根据300 t钢包RH真空处理超低碳铝镇静钢工业生产数据,建立了RH处理过程钢中总氧含量(氧化物夹杂含量)的预报模型.模型综合考虑了RH脱碳结束时钢中的初始氧[O]_o及钢包渣中(FeO+MnO)的质量分数、吹氩流量、真空度、处理时间等因素的影响.模型计算值与实测值误差为士(3.5～8.0)%,说明该模型是可信的;利用模型分析讨论了RH操作过程的工艺因素对钢水总氧含量的影响.
Based on the industrial production data about ultra-low-carbon Al-killed steel produced by RH(300 t ladle) vacuum treatment, a prediction model was built for total oxygen content, namely the quantity of inclusions in steel in RH process. Different influence factors are considered such as initial oxygen content [O]_o, (FeO+MnO)in slag, flow rate of argon blowing, vacuum degree, treatment time and so on. The error range between the calculated values and the measured values is ±(3.5～8.0)%, which indicates that this model is reliable. It has certain guidance to the practical production that analyzing the influences of technological factors in RH process on the total oxygen content in molten steel by this model.
