Embodiment 1

[0016] For heat treatment under the combined conditions of vacuum and transverse magnetic field, the specific steps are as follows: place the magnetic core in the material rack (make the corresponding material rack according to the size of the magnetic core), and put the material rack into the furnace; start the vacuum device and open the vacuum valve , vacuum the inside of the furnace, and keep the vacuum degree at 1×10 -3 -5×10 -3 Pa; open the heating temperature control table, heat the temperature in the furnace to 550~560 degrees of the crystallization temperature; open the magnetizing coil, adjust the current of the magnetizing coil, the magnetic field of the magnetizing coil is: 0~1500Gs; magnetic core heat treatment After completion, the bottom fan can be used to cool the air duct; the heating wire is controlled by a temperature control table, and the cooling rate can be adjusted. When the temperature in the furnace is cooled to below 300 degrees, the treatment is compl...

Abstract

The invention discloses a high performance magnetic core transverse magnetic field heat treatment furnace, which includes a furnace liner and a material rack fixedly disposed in the furnace liner. The furnace liner is connected to a vacuum pump through a pipeline, a heating wire twines around the furnace liner externally, and an air duct and a magnetized coil are arranged outside the heating wire for separation. An air cooler for cooling the upper air duct is mounted at the furnace liner bottom. The magnetized coil is connected to a control cabinet through a pipeline. For the heating wire and the magnetized coil, power supply control is provided through the control cabinet, and the magnetized coil controls the magnetic field magnitude through current. The iron-based nanocrystalline alloy magnetic core transverse magnetic field heat treatment furnace with the structure combines the advantages of vacuum heat treatment and magnetic heat treatment. As the magnetization treatment is conducted in a vacuum state, the magnetic core has a bright surface and excellent performance. Meanwhile, because of the magnetization treatment, the magnetic performance is stable.

Description

technical field [0001] The invention relates to a high-performance magnetic core transverse magnetic field heat treatment furnace. Background technique [0002] Amorphous alloy material is a new type of alloy material that came out in the 1970s. It adopts the international advanced ultra-quick cooling technology to convert the liquid metal to 1×10. 6 ℃ / s cooling rate is directly cooled to form a solid thin strip with a thickness of 0.02~0.04mm, and an amorphous alloy structure with short-range order and long-range disorder in atomic arrangement and combination is obtained. This alloy has many unique performance characteristics, such as excellent Magnetic, corrosion resistance, wear resistance, high hardness, high strength, high resistivity, etc. Because of its excellent performance and simple production process, it has become the focus of research, development and application in the material science community at home and abroad since the 1980s. It is used in the electric p...
