在计算高炉内>1000℃直接还原带和风口燃烧带物料平衡和热平衡的基础上,根据铁水含硅和(或)铁水温度与风口焦炭的理论温度Tc间存在的线性函数关系,从而得出了表征炉子高温区热状态及预测铁水含硅和(或)铁水温度的数学模型。为验证模型的预测效果,编制了相应的计算机应用软件系统,通过该系统运行,按每采样周期,能显示及打印算出的Tc值和预测值,并可根据操作者的需要,随时显示和打印前24小时内的Tc时序列曲线。选择梅山炼铁厂2号高炉进行预测铁水含硅和铁水温度的工业性试验,经与44炉铁水实测值比较后,预测命中率分别达到79.55
Based on the calculation of the material balance and thermal balance of blast furnace blast furnace with> 1000 ℃ direct reduction zone and tuyere combustion zone, based on the linear function between the temperature of silicon and / or hot metal in blast furnace and the theoretical temperature Tc of tuyere, A mathematical model for characterizing the thermal state of the furnace in high temperature zone and predicting the temperature of silicon and / or hot metal in the hot metal. In order to verify the predictive effect of the model, a corresponding computer application software system has been compiled. By running the system, the calculated Tc values and predicted values can be displayed and printed according to the sampling period, and can be displayed and printed at any time according to the needs of the operator Tc time series curve in the first 24 hours. Select the No.2 blast furnace in the Meishan Iron Works to test the industrial tests for the temperature of silicon and molten iron in the molten iron. After comparing with the measured values of 44 molten irons, the predicted hit rates are 79.55
