钨板轧制的轧制力模型研究

Mathematical Model of Rolling Force for Tungsten Plate Rolling

为了使钨板轧制过程中的各项轧制参数得到有效控制,对钨板轧制数学模型进行了研究。首先在Gleeble热模拟机上进行热压缩试验,研究了变形抗力与各种变形条件的关系,确定了变形抗力模型;通过550mm轧机轧制钨板时采集到的有关数据,建立了应力状态影响系数数学模型、变形区长度等模型;最终建立了550mm钨板轧机轧制力模型。利用模型计算值与实际测量参数进行了对比,结果比较满意。

Compression tests are carried out through simulator Gleeblel500 to measure the high temperature deformation resistance of tungsten plate under different deformation conditions in order to establish the deformation resistance model for tungsten plate. Based on the practical parameters from the 550 mm mill, an influential coefficient model, a deformation zone length model and a rolling force model were established.
