5052铝合金板带热粗轧轧制力模型的研究

Study on rolling force model in the hot-rolling process of 5052 aluminium alloys

以经典轧制理论为依据,对5052铝合金板带热粗轧过程的轧制力模型进行研究。详细分析了轧辊的弹性压扁半径、应力状态系数和轧件变形抗力三个因素对轧制力的影响。用MATLAB建立的粗轧过程轧制力数学模型,使轧制力预测误差控制在5%~7%之间,基本可以满足现场实际生产的要求。

On the basis of classic rolling-theory,rolling force model of 5052 aluminum alloys in hot roughing was investigated.Factors which influenced rolling force including radius of elastic flattened roll,stress stat coefficient and average yield stress（deformation resistance） were evaluated in order to establish the model.The rolling force program was developed by means of MATLAB and the comparison between calculations and measured values of the rolling force indicated that the rolling force model has good precision of prediction with an error between 5%~7%.
