Abstract
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.
