Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this
The accompanying drawing of inventive embodiments, is clearly and completely described the technical scheme of the embodiment of the present invention.
Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.
Based on described embodiments of the invention, those of ordinary skill in the art are without creative work
The every other embodiment obtained under premise, broadly falls into the scope of protection of the invention.
Definition:
In this application, term " large Barkhusen effect " refers to what amorphous band or fiber were had
A kind of characteristic, i.e. the movement of this material domain wall generation saltatory in magnetic history or reversion, this mistake
Journey can be detected by instrument.When actual detection, amorphous band or fiber are put into alternation
In magnetic field, after magnetic field reaches the switch yard of material, the magnetic domain generation instantaneous variation of material, detector
Device just can sense a distinctive electromagnetic signal.In some embodiments, wherein generate
Electromagnetic signal is pulse signal or higher hamonic wave.In the present invention, amorphous fiber has large Barkhusen effect,
As it is shown on figure 3, under the excitation of alternating magnetic field, when reaching a switching magnetic field value, magnetic induction is strong
Degree can jump, thus generates an electromagnetic signal, such as: pulse signal or higher hamonic wave.When
Detecting instrument will be reported to the police when detecting the electromagnetic signal that amorphous fiber produces.
In this application, term " melt czochralski method " refers to be made by the steps amorphous fiber
Method:
In the present invention, amorphous naked fiber uses melt czochralski method to prepare, (as shown in Figure 3) specific as follows:
First the foundry alloy rod with required composition is provided；
2. the mode utilizing sensing heating or LASER HEATING melts foundry alloy so that foundry alloy upper end is formed
One stable weld pool；
3. upwards fed foundry alloy by machinery, utilize the portion that guider is connected with foundry alloy simultaneously
Foundry alloy is cooled down by position, prevents the part beyond foundry alloy top from melting；
4. the foundry alloy of fusing is cut by the copper wheel of the high speed rotating using edge to be taper, obtains
Amorphous naked fiber.
