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。
Many scholars found in the experiment that the minimum thickness of rolled steel obtained by the experiment is much smaller than that calculated by the formula of the minimum usable thickness of rolled steel. In view of the above problems, the theoretical analysis of the minimum thickness can be rolled to deduce the new minimum thickness formula. The new formula calculates the minimum rollable thickness of about Stone calculated 22% of the results. Through the laboratory two-roll mill for 304 stainless steel, pure aluminum, pure copper very thin strip rolling test, measured the minimum thickness of different materials can be tested. Comparing the measured results with the new formula and the Stone formula, it is found that the new formula is closer to the measured result, which verifies the accuracy of the model.
