Abstract

The invention provides a method for achieving an alternating or pulsed magnetic field action through static magnetic field facilities, and relates to the technical field of material processing. The multiple static magnetic field facilities are ingeniously arranged along a production line, the magnetic field intensity and directions of the static magnetic field facilities at the corresponding positions are adjusted according to the original alternating or pulsed magnetic field waveform and waveform parameters required by products conveyed by the production line, and a static magnetic field is infinitely close to the treatment effect of an alternating magnetic field or a pulsed magnetic field in cooperation with the moving speed of the products on the continuous production line. The problem that in the prior art, an alternating or pulsed magnetic field cannot be effectively applied to material stress and performance regulation and control in a continuous production line is solved.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a method for realizing alternating or pulsed magnetic field action through static magnetic field facilities in continuous production lines. Background technique [0002] The ability of magnetic fields to regulate the surface stress, processing and performance of materials has gradually become a consensus in the field of material processing and modification, making the application of magnetic fields in industrial production gradually increasing. In the application process, it was found that alternating magnetic fields or pulsed magnetic fields have better effects than static magnetic fields. However, the generation of alternating magnetic field or pulsed magnetic field is much more difficult than that of static magnetic field, and the requirements for generating equipment are higher, which increases the production cost and is not easy to be coupled with traditional pro...
