The present invention relates to the technical field of extruding, rolling and drawing metal wire or rod with assistance of a combined static magnetic field, characterized by providing, in a moving direction of a metal wire or rod, a gradient static magnetic field generated by a combination of a permanent magnet and a steady electromagnet; and after a raw material for rolling the metal wire or rod is processed by the gradient static magnetic field, performing rolling extrusion and pulling on the material. For multiple passes of rolling extrusion and pulling, the static magnetic field processing is performed before each pass of rolling.

A guide roller configured to guide a wire to or from a work roller in a wire rolling line includes a rolling-element bearing having a rotatable outer ring, a fixed inner ring, and rolling elements between the outer ring and the inner ring. The outer ring has a profile configured to guide the wire on a radially outer surface thereof. The guide roller is configured as a double row preloaded rolling-element bearing and is installable as a finished component on a fixed shaft of the wire rolling line without adjusting the preload.
