A method and apparatus for processing metallic material within complex magnetic field

Abstract

The invention relates to a method for the high temperature processing of metal material under a composite magnetic field. In the solidification process of the metal material, a pulsed magnetic field and a superconducting magnetic field which are coaxial in the same direction are applied to a metal bath, to control the grain size and the crystal orientation. A device applied by the method of the invention comprises a heating furnace body (2), a pulsed magnet (3), a superconducting magnet (4), a water cooling jacket (5), a heating control system (11), a pulsed magnet power (12), a superconducting magnet power (13), and a circulating cold water equipment (14). The central axle lines of the heating furnace body (2), the pulsed magnet (3), and the superconducting magnet (4) are coincident; the heating furnace body (2), the pulsed magnet (3), and the superconducting magnet (4) are nested layer by layers from inside to outside. The invention can perform the comprehensive optimal control to the organizational structure of the material, while the superconducting magnetic field optimizes the crystal orientation, the composite magnetic field also plays the function of strengthening the grain refinement; the two magnetic field technical methods of the prior pulsed magnetic field processing and the strong magnetic field processing are integrated into a whole, thereby simplifying the process flow, and reducing the energy consumption.
