摘　　要：应用红外测试仪测得的炉气数据,根据转炉熔池物料平衡和热平衡,通过模型计算,论证了炉气分析在转炉连续控制中对碳和温度预报的可行性,并得出结论:炉气分析对终点w(C)≤0.06%炉次的碳预报命中率较高,适用于低碳钢冶炼。但该模型进行温度预报的数据来源均为间接数据,命中率较低。Based on the data of gas acquired from the infrared analyzer and model calculation as well as on the material balance and thermal equilibrium in the bath of converter the present paper demonstrates the feasibility of prediction on the carbon content and temperature in continuous control of the converter by way of gas analysis and then reaches the conclusion that a higher hit rate can be achieved by gas analysis when the end point carbon content is less than 0. 06 % and is more suitable for refining low carbon steel. However since all data for predicting the temperature are acquired indirectly the hit rate of temperature prediction is inevitably lower by the gas analysis.
