Problems solved by technology

But it also has some disadvantages: on the one hand, since the amorphous forming elements must be added, it is difficult for the saturation magnetic induction of iron-based amorphous alloys to match that of silicon steel, which makes the volume of amorphous coils with the same core power larger than that of silicon steel coils
On the other hand, in order to maintain the saturation magnetic induction of Fe-based amorphous alloys, high Fe content usually leads to weaker formation ability of amorphous alloys

Embodiment 1

[0025] The purity of the alloy raw materials Fe, Co, Si, B, Fe-20%P and Ti used in this embodiment is 99.9wt.%.

[0026] This embodiment prepares Fe according to the following steps 80.3 co 4 Si 4 B 8 P 3 Ti 0.7 Strip:

[0027] Step 1. Processing of raw materials

[0028] Fe, Co, Si, B, Fe-20% P and Ti raw materials are taken, and the oxides and grease substances on the surface are removed through mechanical grinding, alkali cleaning, degreasing, and pickling, so as to ensure that there are no other impurities on the surface of the raw materials.

[0029] Step 2, preparation of master alloy ingot

[0030] According to the nominal composition Fe 80.3 co 4 Si 4 B 8 P 3 Ti 0.7 , batching the processed raw materials, and then smelting in a vacuum arc melting furnace under the protection of high-purity argon. In order to ensure uniform alloy composition, the master alloy is repeatedly smelted in the furnace for more than 4 times to obtain a master alloy ingot;
