Second step, prepares iron-based amorphous and nanocrystalline soft magnetic alloy iron core product:
The obtained Fe-based amorphous iron core of above-mentioned first step volume is put into annealing furnace, is annealed, obtained at 540~580 DEG C
It is equally distributed nanocrystalline on noncrystal substrate, that is, iron-based amorphous and nanocrystalline soft magnetic alloy iron core product is made.
Determined through slide measure:The size of obtained iron-based amorphous and nanocrystalline soft magnetic alloy iron core product be external diameter × internal diameter ×
Height=D × d × h=Φ 30mm × Φ 24.92mm × (10~40) mm;Calculated according to Jade softwares:The Fe-based amorphous nanometers of AxFy
The mass fraction of crystalline phases is 78.4~86.2% in brilliant soft magnetic alloy core product;Surveyed through MATS-2010SD type soft magnetisms direct current
Amount device determines the product magnetic property and is:Saturation induction density is 1.26~1.49T, and initial permeability is 125k~148k.
