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.
Claims5
A method of preparing metal wires or rods with assistance of a static magnetic field, comprising:
- loading a blank in the form of a metal wire or rod into a conveying roller track to be processed by multiple stages of rolling, extruding or drawing along a travel direction of the blank;
- subjecting the blank to an effect of a static magnetic field before being processed by each of the multiple stages of rolling, extruding or drawing;
- wherein in the conveying roller track a longitudinal center line of the blank is kept in line with the travel direction of the blank;
- wherein before a first stage of rolling, extruding or drawing, the blank is subject to magnetic treatment by a gradient static magnetic field formed by three groups of permanent magnets and a steady electromagnet that are disposed in parallel along the travel direction of the blank on the conveying roller track;
- and
- wherein a magnetic induction intensity of the three groups of permanent magnets increases from group to group along the travel direction of the blank.
