Abstract：The miniaturization, lightweight and mobility of the micromanufacturing and microelectronics industries require the extremethin and the ultrathin metal foil with a thinner thickness and a higher dimensional accuracy, thus the manufacturing technologies of the extremethin and the ultrathin metal foil are becoming more and more significant. It is found that Stone’s minimums rolling thickness is more unreasonable in the experiment and the production practice. The contact profile and the rolling pressure of the ultrathin foil strip with different thicknesses at different reduction rates are obtained by means of the finite element simulation, which gives a new meaning to the Stone′s minimum rolling thickness formula, the critical thickness of whether there is a neutral zone under the condition of the minimum reduction deformation. An analytical calculation model for the gauge suitable to roll in the ultrathin strip rolling is established and the plastic deformation can be calculated according to the rolling force condition and the thickness of the foil strip, providing a theoretical guidance for the practical production by defining product specification ranges and rolling regulations for existing rolling mills and determining roller diameters or force and energy parameters when design rolling mills.
