| 摘 要： | 建立了RH—MFB精炼过程中钢水温度的数学模型，通过Delphi程序计算了精炼过程中钢水的温度．结果表明，RHMFB精炼开始阶段，钢水温度急剧下降，前10min降温速率约为3℃·min-1．加Al吹氧、加合金和真空室内壁初始温度对钢水温度影响较大．采用该模型预测了精炼结束时刻的钢水温度，与生产中钢水温度平均误差在±5℃以内的占80%． |

| Abstract: | A mathematical model of RH-MFB process was developed. The temperature of molten steel can be calculated by Delphi program. The results show that the temperature of molten steel declines drastically in the beginning of refining, and the speed of temperature drop is approximately 3 ℃·min-1 in the first 10 min. Al addition, blowing oxygen, alloy addition and the initial temperature of the vacuum vessel wall have more effect on the temperature of molten steel. A comparison between the calculated and measured temperatures shows that the values with average errors in ±5℃ is by 80 % for predicting the temperature of molten steel at the end-point of RH-MFB process. |
