【摘要】：许多学者在试验中发现,试验得到的最小可轧厚度远小于常用最小可轧厚度公式计算得到的结果。针对上述问题,进行了最小可轧厚度理论分析,推导出新的最小可轧厚度公式。新公式计算的最小可轧厚度约为Stone公式计算结果的22%。通过实验室二辊轧机进行304不锈钢、纯铝、纯铜极薄带轧制试验,实测得到不同材质的试验最小可轧厚度。将实测结果和新公式计算结果及Stone公式计算结果进行对比,发现新公式计算结果更接近于实测结果,从而验证了模型的准确性。
[Abstract]:Many scholars have found that the minimum rolling thickness obtained in the experiment is far less than that obtained from the calculation of the commonly used formula for the minimum rolling thickness. In view of the above problems, the theoretical analysis of the minimum rolling thickness is carried out, and a new formula for the minimum rolling thickness is derived. The minimum rolling thickness calculated by the new formula is about 22 of the result of the Stone formula. The rolling test of 304 stainless steel, pure aluminum and pure copper thin strip was carried out by two high roll mill in laboratory. The minimum rolling thickness of different materials was obtained. By comparing the measured results with the calculated results of the new formula and the Stone formula, it is found that the new formula is closer to the measured results, which verifies the accuracy of the model.
