摘　　要：以转炉连续检测的烟气成分为过程参数,以质量平衡理论和不可逆过程的非平衡态热力学理论为基础建立转炉过程动态模型,推算吹炼过程熔池碳含量和温度.通过建立模型过程中引入氧枪枪位,并对烟气的流量、系统滞后时间进行校正,以及运用不可逆过程热力学确定熔池的反应温度,有效提高了模型的精度.A mathematical model for the LD process was deduced on the basis of material balance and thermodynamics of the irreversible process with on-line information of off-gas to calculate the carbon content and temperature of the steel bath. The model precision was enhanced with the introduction of the launch height and modification of gas flux and lag time. The dynamic variation of temperature of the steel bath was determined with the aid of the thermodynamics of the irreversible process.
