Description
Technical Field
The utility model relates to the technical field of amorphous magnetic core magnetic field heat treatment, in particular to a transverse magnetic field heat treatment device for an amorphous magnetic core of a horizontal heat treatment furnace.
Background
The iron-based amorphous nanocrystalline soft magnetic material has excellent soft magnetic properties such as high initial permeability, high saturation magnetic induction, low coercive force, low loss and the like, and has wide application prospect. The research and the commercialization development of the material from the material research and development to the application field have achieved remarkable results, and the application field of the iron-based nanocrystalline alloy material is an iron core of a power transformer, a high-power switching power supply, an inverter power supply, a common-mode inductance iron core and the like.
Annealing heat treatment is a very important step in the preparation process of the iron-based amorphous alloy magnetic core. The aim is to reduce the hardness of the material and improve its function; eliminate residual stress and reduce deformation degree; the crystal grains are refined, and the internal defects are eliminated. The annealing can eliminate the stress caused in the process of manufacturing the magnetic core, thereby exerting the optimal soft magnetic performance of the iron-based amorphous alloy magnetic core.
In actual production, for amorphous nanocrystalline products, the magnetic core qualification rate is low after conventional heat treatment, and the industrialized demand cannot be met. In order to improve the qualification rate and meet the design requirements, a more effective magnetic field heat treatment mode is needed to improve the product performance. The magnetic field heat treatment is that when the material is subjected to heat treatment, a magnetic field is applied, the structure of the material is not changed in the process, but the shape of a hysteresis loop of the material is changed. The magnetic field heat treatment is actually a thermodynamic process, under the action of an external magnetic field, the heat energy of the system is activated, atoms are rearranged, the free energy of the system is reduced, when the temperature of the system is reduced, the rearranged atomic sequence is reserved, a simpler magnetic domain structure and higher induced uniaxial anisotropy are formed, the coercive force of the material is reduced, and the comprehensive soft magnetic performance of the material is improved.
Transverse magnetic heat treatment means that the direction of an external magnetic field is perpendicular to the direction of a casting surface of a strip (the direction of a magnetic circuit when a magnetic core works), and the method can reduce the coercive force and the remanence ratio Br/BS of the material to a certain extent; and the linear flatness of the hysteresis loop can be regulated and controlled by controlling the magnetic field intensity and the annealing temperature. The magnetic conductivity is constant (insensitive to the change of magnetic field intensity and frequency in a certain range); further reducing the iron loss; the magnetic domain junction is changed, so that the magnetic domain structure is simple.
The generation of the transverse magnetic field is relatively simple, and in the case of a horizontal heat treatment furnace, a coil with a certain number of turns is wound on the outer side of the heating furnace and then energized. The magnetic field intensity is controlled by the current. Thereby producing a magnetic field along the length direction of the hearth, and the magnetic core needs to be placed in the direction vertical to the hearth, so that a transverse magnetic field can be produced.
When most of the existing annular magnetic cores are subjected to transverse magnetic field heat treatment, the magnetic cores are overlapped together or are closely arranged together, so that the temperature of the magnetic cores at different positions is easily uneven, and the soft magnetic performance of different magnetic cores is easily inconsistent due to the difference of heat treatment temperatures.
