【摘要】 介绍了一套自主开发的热轧工艺参数模型．该模型内耦合了不同钢种的变形抗力曲线, 这些变形抗力方程中耦合了钢的化学成分、温度、应变、应变速率及奥氏体晶粒尺寸等因素．根据输入的工艺参数用西姆斯方程计算每道次的应变速率及应变量,并得到相应道次的变形抗力、热轧轧制力、力矩及功率等参数．模型可根据实测的结果自学习,并修正相应的结果．与攀钢热轧厂的实测结果相比,模型的输出结果吻合较好,预测误差在10％以内．更多还原

【Abstract】 A model was developed to predict the hot rolling parameters such as rolling force, torque and power etc. For various flow stress equations were coupled which take into account of chemical composition, temperature,strain, strain rate and austenite grain size, the model can automatically calculate the rolling parameters based on input process parameters and calculated strain, strain rate in every pass. According to the real measured data this model can adjust its output. Compared with the mill data of Panzhihua Iron and Steel Company, the model is in a good agreement with no more than 10% deviation.更多还原
