ABSTRACT:
A method and an arrangement for finish rolling wire and/or round steel on a continuously operating finish rolling block. The finish rolling block includes a plurality of work rolling sets and sizing rolling sets with essentially round sizing rolls, wherein the rolling sets are arranged closely one behind the other and the rolling planes thereof are alternatingly offset relative to each other by 90.degree.. The method includes imparting a twist to the rolled material by asymmetrically spreading the rolled material in the two sets of rolls which precede the last set of rolls, wherein the twist imparted in the two sets of rolls has approximately the same magnitude but is directed in opposite directions, so that the rolled material is stabilized in its position in the last sizing roll pass.
