【摘要】 利用转炉吹炼末期脱碳动力学方程建立了转炉终点碳动态预测模型,并用实际生产数据对模型进行了验证,取得了比较高的命中率；通过回归的方法,得出了终点碳氧关系曲线,并利用该曲线方程建立了转炉终点氧预测模型,取得了比较好的预测效果,同时利用对该模型预测偏差的分析,可以为确定转炉修补的时机提供依据。更多还原

【Abstract】 Make the dynamic predication model for end point carbon by the final phase dynamics model ofdecarburization in BOF,and use the factual data to verify the model,it gained better percentage of hits.By regression analysis,it gained the relation curve of end point carbon and oxygen.And make the dynamic predication model for end point oxygen by the equation of this curve,it also gained better percentage of hits.Meanwhile,by analyzing the deviation of the model predication,it can supply basis for the time to repair the BOF.更多还原
