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 measured results， which verifies the accuracy of the new model.
