【摘要】 许多学者在实验中发现,实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,本文进行了最小可轧厚度理论分析,推导出新的考虑轧制力限制的条件最小可轧厚度和不考虑轧制力限制的理论最小可轧厚度公式,理论最小可轧厚度约为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、纯铜极薄带轧制实验,实测了不同材质在不同轧制力下的实验最小可轧厚度,发现本文公式计算结果实测结果非常吻合,验证了本文最小可轧厚度理论的正确性,从而解决了存在半个多世纪的最小可轧厚度计算不准确问题。更多还原

【Abstract】 Most scholars have found that the minimum thickness obtained by the experiment is much smaller than that calculated by the common formula of the minimum thickness. In view of the above problem, the theory of the minimum thickness was analyzed, and then a new formula of the minimum thickness was deduced. The minimum thickness calculated by the new model is about 22% of the Stone formula. Finally, the minimum thickness of 304 stainless steel, pure aluminum and pure copper was obtained by a two-high mill. By comparing the measured results with the calculated results of the new model and the Stone formula, it is found that the calculations of the new model are closer to the measurement, which verifies the accuracy of the new model.更多还原
