Example Embodiment
[0013] In Embodiment 2, the device is a circular ring made of AlNiCo or FeCoV alloy with a diameter of Φ100mm. The device of the present invention is used for magnetic field heat treatment. The rotation speed of shaft C is 30-60 rpm. When heating, a magnetic field is applied with an intensity of 1000- 2000Oe, the heat treatment temperature is 700-850°C, and the holding time is 1-2 hours. The uniformity of the magnetic flux after magnetization of the device is similar to the results in Table 1 (the details are omitted).

A heat treating technology of magnetic device in a rotating magnetic field features that after a maganetic device is fixed to a rotary axle driven by a motor, it is arranged in a heating furnace and a magnetic field for magnetizing it uniformly.
Description
technical field [0001] The invention belongs to the technical field of magnetic devices, and in particular relates to a magnetic field heat treatment method and device for magnetic devices. Background technique [0002] At present, the traditional magnetic field heat treatment at home and abroad is to place the device in a furnace with a magnetic field for static heat treatment, and to improve the magnetic properties of the device through a certain magnetic field and heat treatment temperature, such as magnetic devices processed by AlNiCo, FeCrCo, FeNi alloys, etc. use this method. However, after such treatment, the magnetic inhomogeneity of each part of the device often reaches about 20%. Such magnetic devices, especially those with larger cross-sections, cannot meet the technical requirements of use. Contents of the invention [0003] The object of the present invention is to provide a magnetic field heat treatment method and device for a magnetic device with high magn...
