Rolling mill finishing section

A method and apparatus for finish rolling long products such as bars, rods and the like, comprising: in a first operational mode, rolling the products through a finishing block (14) and a reducing sizing mill (20) arranged on a primary pass line (P1); and in a second operational mode, diverting the products from the primary pass line to a secondary pass line (P2), bypassing the finishing block and then back to the primary pass line for rolling in the reducing sizing mill. Optionally and preferably, a cooling unit (16) is shifted between the primary and secondary pass lines to cool products being rolled in each operational mode.
