Abstract
A rolling mill and method for rolling material having a rectangular, oval or like elongated cross-sectional configuration into rod or wire, has a line of passes of which the first pass is formed by two rollers and the remaining passes are each formed by three rollers, and wherein the first pass deforms the material, whose input cross section has a ratio of the lengths of its major and minor principal axes greater than about 1:2 to an output cross section which is exactly round or a regular polygon, such as square or hexagonal or which deviates from such a geometrical configuration only to an extent such that the ratio of the lengths of the major and minor principal axes of the output cross section does not exceed about 1:2.
