A process and unit for hot- and cold-rolling ferrous and non-ferrous metals in order to produce a round bar or wire rod from a round bar or wire rod having a larger diameter. The process consists in inserting a bar or wire rod, whose initial profile has a round cross-section, in a rolling unit which is provided with rolling rolls whose profiles define a round passage whose diameter is smaller than the diameter of the input bar or wire rod. Upstream from the rolling unit, the larger-diameter bar or wire rod is subjected to the action of free rollers whose profiles are suitable to deform the larger-diameter bar or wire rod according to a shape which produces, in output from the rolling unit, a bar or wire rod whose cross-section is round and has a smaller diameter.
In combination, a bar having a bar axis and a standard size diameter and exiting from a conventional rolling mill, and a rolling unit for reducing said diameter of said bar, said rolling unit comprising;
