摘　　要：为了提高热轧带钢卷取温度控制精度,针对热轧带钢轧后冷却过程非线性、强耦合性等特性,建立了具有非线性结构特征的热轧带钢轧后冷却过程控制的温度数学模型,并对热轧带钢轧后冷却过程卷取温度的设定策略进行了研究,同时在该模型基础上开发了系统软件,通过现场实际应用对模型功能进行了验证.结果表明,该冷却数学模型的卷取温度设定计算结果与实测结果吻合较好,卷取温度控制精度可达到±10℃,表明该模型取得了较好的应用效果,能够达到较高的控制精度.To control the coiling temperature of the hot-rolled strip more accurately,the nonlinearity and strong coupling features of the cooling process were taken into account so as to develop a mathematical model for the temperature control in the cooling process after strip＇s hot rolling with the nonlinear characteristics involved.Then,the strategy of coiling temperature setting was investigated in relation to the cooling process.A system software was therefore developed on the basis of the model and the effect of the model was verified via in-situ applications.It was found that the setting value of coiling temperature calculated from the model conforms well to the measured value,i.e.,the control accuracy of coiling temperature comes up to ±10 ℃.It means that the model is applicable to actual applications.
