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。
In order to control the rolling parameters of tungsten plate effectively, the mathematic model of tungsten plate was studied. First, the thermal compression test was carried out on a Gleeble thermal simulator to study the relationship between deformation resistance and various deformation conditions and determine the deformation resistance model. Based on the data collected during the rolling of the tungsten plate by 550mm rolling mill, Model, the length of the deformation zone model; finally established 550mm tungsten plate rolling mill force model. The calculated values are compared with the actual measured parameters, and the results are satisfactory.
