Embodiment 1
[0025] The present embodiment adopts following preparation technology:
[0026] Step 1: Select an alloy material with an amorphous cobalt-based amorphous material and a thickness of 23um;
[0027] Step 2: Winding with a winding machine needs such as figure 1 Dimensions of inner diameter ID, outer diameter OD, height HT shown;
[0028] Step 3: Raise the temperature of the vacuum annealing furnace to the preset temperature of 300 degrees;
[0029] Step 4: Put the wound magnetic core into the vacuum annealing furnace in Step 3 for annealing treatment;
[0030] Step 5: Use the instrument to control the annealing temperature, starting from 300 degrees, and use 80 minutes to raise the temperature to 350 degrees, and then keep warm for 70 minutes to crystallize the magnetic core. The vacuum pump is not turned on during the whole process to oxidize the magnetic core, and the heat preservation is over. Finally, take out the magnetic core and quickly cool down to room temperature;
