10008-MB ABSTRACT OF THE DISCLOSURE An apparatus and process for rolling metal strip to provide increased percentage reductions in the thickness of the strip per pass and increased total reduction between anneals. A 4-high rolling mill is modified so that it is back-up roll driven such that the back-up rolls have different peripheral speeds in the same ratio as the desired strip reduction. The strip travels through the mill in a serpentine arrangement to provide three reductions per pass. Forward and back tension are applied to the strip during rolling.
