Embodiment 1

[0044] The heat treatment in the non-vacuum treatment process, the specific steps are: open the protective atmosphere device, pass the protective gas into the furnace; place the magnetic core in the furnace, start the power supply of the control cabinet, and control the corresponding temperature by multiple temperature control meters in the control cabinet 5. Multiple heating elements are used to adjust the temperature in the furnace, which can be divided into three processes: preheating, heating, and heat preservation. The temperature adjustment range can be, for example, 100-600°C; during the heating process, a magnetic field is applied to the magnetic core and then removed. Under the limit of the position of the proximity switch, the fixing device with the permanent magnet is moved to the position of the heating furnace through the magnetic field controller, and the withdrawal action is reversed; the power is turned off, the magnetic core is directly taken out, and the magnet...

Embodiment 2

[0046] Heat treatment in the non-vacuum treatment process, the specific steps are: open the protective atmosphere device, pass protective gas into the furnace; place the magnetic core in the furnace, add a magnetic field and start the control cabinet power; turn off the power, withdraw the magnetic field, and the furnace The core cools with the furnace.

Abstract

The invention discloses a magnetic field heat treatment furnace which comprises a furnace frame (1), heating furnaces (2) arranged on the furnace frame, a water cooling system (3) and a magnetic fieldsystem (4), wherein the water cooling system (3) comprises cooling water plates (6) and a cooling machine (7) connected to the cooling water plates (6) via pipes; the cooling water plates (6) are fixed above and below the heating furnaces (2); the magnetic field system (4) comprises a permanent magnet (8), a fixing device (9), a transmission device (11) and a controller (12); the permanent magnet(8) comprises two opposite magnetic poles oppositely mounted on the fixing device (9); the fixing device (9) is arranged on the furnace frame and connected to the transmission device (11) and the controller (12), so that the fixing device (9) can be moved in the horizontal direction, and the heating furnaces can enter between the two opposite magnetic poles. The consistency of the temperature inthe furnace is improved, and the stability and consistency of performance of magnetic cores in the same furnace are improved.

Description

technical field [0001] The invention relates to the technical field of amorphous magnetic core processing, and more particularly relates to a magnetic field heat treatment furnace. Background technique [0002] Amorphous alloys are synthesized by modern rapid solidification metallurgical technology. The arrangement of internal atoms in three-dimensional space does not have periodic repeatability and translational symmetry, and has a random close-packed structure. Therefore, there are no crystal defects such as grain boundaries and dislocations inside the material. , thus showing high strength, corrosion resistance, wear resistance and excellent magnetic properties. Iron-based amorphous alloys have the characteristics of high saturation magnetic induction, high magnetic permeability, low coercive force, low core loss and large resistivity, and are widely favored by the electric power and electronics industries, and are used as transformers, mutual inductors It is a kind of g...
