DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a long ribbon-shaped amorphous metal, and more particularly to an apparatus for manufacturing an amorphous metal in which different metals are arranged side by side in the short direction.

In recent years, amorphous metals, especially amorphous metals obtained by rapidly quenching molten metals, have attracted attention due to their unique magnetic properties and mechanical properties. metal(
Hereinafter, it shall include alloys.

), most of them consisted of

Therefore, as electronic devices become more sophisticated, smaller, and more reliable, it is desired to develop composite amorphous metals with various complex functions. When a composite amorphous metal is obtained by joining different types of amorphous metals by electrodeposition or the like, the process is complicated and sufficient mechanical joining force cannot be obtained.

Furthermore, there are problems such as the inability to perform heat treatment when joining different types of amorphous metals, and no practically effective means have yet been found.

In view of the above points, the present invention aims to provide a manufacturing apparatus capable of obtaining a long ribbon-shaped composite amorphous metal in which different types of amorphous metals are juxtaposed in the direction of the rotation axis of a high-speed rotating roll. purpose.

The present invention includes a plurality of tubular containers for heating and melting different types of raw material metals, a nozzle provided in the tubular containers and ejecting different types of molten metal using inert gas pressure, and molten metal ejected from the nozzles. Equipped with high-speed rotating rolls that rapidly quench the amorphous metal to obtain a long ribbon-shaped amorphous metal.
In the manufacturing apparatus for manufacturing a composite amorphous metal, the nozzles are arranged in the axial direction of the high speed rotating roll so that the different types of molten metal are arranged side by side in the direction of the roll rotation axis on the high speed rotating roll. This is manufacturing equipment.

That is, the composite amorphous metal manufacturing apparatus according to the present invention is configured as shown in FIG. 1, for example.

Nozzles 2, 2' are provided at the lower ends of tubular containers 1, 1' formed of quartz tubes or the like, in which different raw material metals are individually melted by high-frequency melting or the like.

In addition, high-speed rotating rolls 3 or 3, 3' (FIG. 1 a shows a single-roll method) are used to turn the raw metal ejected by inert gas pressure into an amorphous metal by high-speed quenching corresponding to the nozzles 2, 2'. , b shows the case using the twin roll method.

) is provided. By manufacturing a composite amorphous metal as shown in FIG. 2 in which different types of non-quality alloys 4, 5 are continuously arranged side by side using the above-mentioned manufacturing apparatus, different types of amorphous alloys 4, 5 can be produced. without mixing by pressing the button on the joint, and
An excellent composite amorphous metal with sufficient mechanical strength can be obtained.

The arrangement of the nozzle, high-speed rotating roll, etc. shown in FIG. 1 is appropriately adjusted depending on the roll rotation speed, inert gas pressure, nozzle diameter, type of raw material metal, etc.

The present invention will be described in detail below using an example in which a composite amorphous alloy was manufactured using the manufacturing apparatus according to the present invention.

Example-1 Two types of raw metal C prepared in advance by high-frequency melting
Q'75 Sl 15 B1 □Alloy 29 and Fe
75Si15 Bto alloy (2 g) were respectively inserted into the tubular containers 1.1' shown in FIG. 1a, and heated and melted in an electric furnace while flowing argon gas.

Therefore, 2 atm of argon gas was sent into the tubular vessels 1 and 1', and the molten raw metal was heated at 5.000 rpm using the nozzles 2 and 2' with a nozzle diameter (+, 5 mm) and a nozzle interval of 2.
The mixture was simultaneously ejected onto one roll 3 rotating at a high speed of pm, and quenched at a high speed.

The resulting sample is C07 with a width of 3.4 mm and a thickness of approximately 40 μm.
It was a long ribbon-shaped composite amorphous metal in which a 55i15 layer 5 and a Fe75Si15B1o layer 5 were joined.

When X-ray diffraction measurements were performed, it was confirmed that buttons 5 and 6 were amorphous.

When the boundary state of both alloys was examined using an X-ray microanalyzer, the boundary region was clear.

This was also confirmed by magnetic measurement results.

That is, when the above ribbon-shaped alloy was wound around a ceramic winding frame and its DC magnetization characteristics were measured, a stepped hysteresis curve as shown in FIG. 3 was obtained.

This shows that the two metals are sharply bounded.

Materials having such step-like hysteresis are suitable for latching relays.

Example-2 Three types of raw metal C prepared in advance by high-frequency melting
0755i15 Blo, Fe755i15Bto+

f', and the molten raw metal was simultaneously jetted onto a single roll 3 rotating at a high speed of 5.00 rpm using nozzles 2, 2', and 2' with a nozzle diameter of 0.51 rL1 rL and a nozzle interval of 2 mm, and was rapidly quenched.

The resulting sample is C0755 with a width of 5.3 plates and a thickness of approximately 40 μm.
Its Bt.

Each layer was confirmed to be amorphous.

When the boundary state of the three types of alloys was examined using an X-ray microanalyzer, the boundary region was clear.

Example-3 Cu3o Ni2O button and Co75 as two types of alloys
A composite alloy consisting of stripes of both alloys was obtained by conducting an experiment in the same manner as in Example 1 except that 3i15 Bio was used.

X-ray diffraction revealed that CuB N12o (111 is crystalline, C0755i15 Bt).

The sides were amorphous.

When the boundary state was examined using an optical microscope, there was no sagging of the boundary phase.

Example 3 shows the case of a composite amorphous metal consisting of an amorphous metal and a crystalline metal. It is clear that the process becomes extremely easy, and a composite amorphous metal with clear boundaries and sufficient mechanical strength to be buttoned at the joint can be obtained.

As described above, the apparatus for producing a composite amorphous alloy according to the present invention is capable of continuously and easily obtaining an excellent composite amorphous metal in the form of a long ribbon having different types of metal layers in the short direction. It can be used in various composite functional materials such as magnetic materials and composite contact materials, and can be said to have great industrial utility value.
