ABSTRACT:
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.
