The amorphous material keeps the disordered atomic arrangement state of the liquid up to the solid state without crystallization time when the metal cools in the molten state and is cooled at a rate faster than the critical cooling rate . That is, in the liquid phase cooled at a rate faster than the critical cooling rate, the viscosity of the liquid phase becomes very high in the sub-cooled liquid phase region below the equilibrium melting point, and the fluidity of atoms in the liquid phase is greatly lowered. Therefore, atoms that lose fluidity at a very fast cooling rate are fixed in a non-equilibrium structure, resulting in solid-state properties. A material having such a structure is referred to as an amorphous material.

Generally, an amorphous fiber is a fiber that is solidly formed in a disordered atomic arrangement state of a liquid phase when atoms are regularly arranged and crystallized in a case where the metal is coagulated in a molten state and cooled at a rate higher than a critical cooling rate, And can be manufactured in the form of a fiber in the process of quenching the charcoal.

Unlike conventional crystalline alloy materials, amorphous materials have a structure similar to a liquid phase that has no crystallinity due to the irregular arrangement of atoms.

Therefore, amorphous alloys are free from crystalline imperfections such as grain boundaries and dislocations, which are characteristics of crystalline alloys, and have excellent softness, toughness, corrosion resistance, superconductivity and the like compared with crystalline metals of the same composition . If an amorphous fiber is made using charcoal, a concrete reinforcing material having excellent corrosion resistance can be produced.

Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art. The shape and size of elements in the drawings may be exaggerated for clarity.

Hereinafter, an amorphous fiber manufacturing apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.

3, the apparatus for manufacturing an amorphous fiber includes an injection nozzle 100 for injecting a molten molten metal downward from a tundish 1, and an injection nozzle 100 provided below the injection nozzle 100, (K) provided on a surface of the cooling roll (200) and formed on the surface of the cooling roll (200), and a cooling roll (200) And a pressurizing supporter 400 for supporting the fiber removing part 300 in the direction of the cooling roll 200. As shown in FIG.

The fiber removing unit 300 may be rotatably mounted on the surface of the cooling roll 200.

As shown in FIG. 3, the tundish 1 is a portion where melted molten metal is stored, and the injection nozzle 100 is a portion mounted on the lower side of the tundish 1 to discharge molten metal.

The cooling roll 200 is a portion formed below the injection nozzle 100 to rapidly cool the molten metal injected from the injection nozzle 100. The cooling roll 200 may be installed close to the lower portion of the injection nozzle 100 and configured to rotate at a high speed.

1, the molten iron in the tundish 1 is discharged to the circumferential surface of the cooling roll 200 rotating at a high speed through the hole of the injection nozzle 100 to form a puddle, An amorphous fiber (F) can be manufactured which is brought into contact with the substrate (200) and rapidly cooled to maintain an amorphous state.

In the manufacturing process of the amorphous fiber (F), a fine fiber which is a defective product is generated depending on the position of the nozzle and the cooling roll (200). The fibers that become the product are about 1mm wide, but the defective microfibers have a diameter of less than 0.1mm and accumulate like dust.

The gap G between the cooling roll 200 and the injection nozzle 100 is an important factor determining the quality and thickness of the amorphous fiber F product. And the quality of the produced amorphous fiber (F) may be deteriorated.

2 is a view showing a gap G between the injection nozzle 100 and the cooling roll 200 measured by an image recognition camera.

As shown in FIG. 2 (a), when fine fibers are not attached between the cooling roll 200 and the nozzle, it is easy to measure the gap G between the cooling roll 200 and the nozzle, It is difficult to measure the gap G between the nozzle and the cooling roll 200 when fine fibers are attached between the cooling roll 200 and the nozzle to form an attachment fiber K as shown in FIG. .

The amorphous fiber F may be produced using a molten iron produced in a blast furnace or a FINEX milling process and the amorphous fiber F may be produced by a method such as atomization, drop tube, melt spinning melt spinning, splat quenching, and the like, for example, by using a rapid quenching method.

The conveyance removing part 330 is disposed on the same axis as the central axis of the roller member 310 and is inserted into the engaging groove formed through the center axis of the roller member 310 in a state where the engaging projection of the conveyance removing part 330 is inserted And can be fastened and integrated by a bolt member.

At this time, the conveyance removing unit 330 is integrated on the same central axis as the roller member 310 and is rotated by the roller member 310 rotating together with the cooling roll 200 without the separate driving unit 470 Can be provided.

6, the conveyance removing unit 330 includes a rotation shaft 331 axially coupled to the center of the roller member 310 and a rotation shaft 331 formed on the outer circumferential surface of the rotation shaft 331, And a spiral brush 335 in which a plurality of brushes are arranged in a spiral direction in the direction of the edge portion (B).

At this time, the brush constituting the spiral brush 335 may be constituted by a bristle brush composed of a steel material. The bristle brush may be made of a material that can be deformed so as to be closely contacted by the cooling roll 200 due to a pressing force applied by the pressing support portion 400.

6 (b), when the roller member 310 is brought into close contact with the cooling roll 200, the spiral brush 335 is brought into close contact with the cooling roll 200 so that the spiral brush 335 The height of the roller member 310 protruding from the rotation shaft 331 may be higher than the height of the roller member 310 protruding from the rotation shaft 331.

This is because the helical brush 335 is closely contacted while being deformed in the direction of the cooling roll 200 by the pressing force applied by the pressing support portion 400 to smoothly adhere the attachment fibers K attached to the cooling roll 200 To remove it.

The height of the screw member 337 protruding from the rotation shaft 331 is set such that the screw member 337 is disposed close to the cooling roll 200 when the roller member 310 is in close contact with the cooling roll 200 The roller member 310 may be formed lower than the height of the roller member 310 protruded from the rotation shaft 331.

This is because if the screw member 337 directly contacts the cooling roll 200, damage may occur to the surface of the cooling roll 200.

Therefore, when the roller member 310 is brought into close contact with the cooling roll 200, the screw member 337 can be disposed slightly spaced from the surface of the cooling roll 200. Therefore, the attachment fibers K can be removed by the screw members 337 when the attachment fibers K are formed at a height higher than the predetermined height on the surface of the cooling roll 200.
