摘要
轧制力是影响带钢平整质量的关键因素。通过分析平整机轧制力模型,充分考虑该平整机的设备工艺特点和实际工况,建立锡板连退平整机合适的轧制力模型。基于目标函数最小值,采用粒子群优化算法,通过调整模型参数提高轧制力模型预报精度。实际应用结果表明:该轧制力模型具有较高的预报精度,对实际现场具有较好的指导作用。
Rolling force is a key factor affecting the quality of the strip.By analyzing rolling force model of the skin pass mill,its technological features and practical situation were considered,and the suitable rolling force model of the skin pass mill was deduced.Based on minimum objective function and particle swarm optimization algorithm,the rolling force model prediction accuracy was improved by adjusting the model parameters.The results show that the determined strip rolling force model has high prediction accuracy,and vital significance in guiding the actual production.
