Abstract
Long products are hot rolled and sized by being subjected to progressively diminishing area reductions in a succession of at least three mechanically interconnected two roll passes driven by a common mill drive. The area reductions are achieved by imparting a first cross sectional configuration to the products rolled in the first roll pass, and by imparting a different second cross sectional configuration to the products being rolled in each of the second and third roll passes. A wide range of product sizes is accommodated by selectively adjusting the speeds at which each of the roll passes is driven by the common mill drive in order to vary the drive speed ratios between successive roll passes.
