Description

Description: TECHNICAL FIELD The present invention relates to a winding device in the production of ultra-quenched ribbon and ultra-quenched wire.

[Prior Art] Conventionally, in this type of manufacturing, a ribbon or a wire rod has been manufactured by injecting an alloy or the like melted by a high-frequency coil or the like onto a quenching rotating roll from a refractory nozzle.

[Problems to be Solved by the Invention] However, in the conventional method, the sprayed molten metal hits the roll surface and solidifies and jumps out in the tangential direction of the roll, but the protruding angle is not constant, and it is difficult to wind this. Therefore, after the injection was completed, it was necessary to rewind or take a large-scale device.

Therefore, in view of the above-mentioned drawbacks, a technical problem of the present invention is to provide an apparatus for performing winding at the same time as injection.

[Means for Solving the Problem] According to the present invention, in a winding device for winding a super-quenched material, a rotatable cooling having an outer peripheral surface that receives an injected molten alloy and rapidly cools it to scatter as a super-quenched material. Roll for
A rotatable drum that has an inner peripheral surface that surrounds and separates the outer peripheral surface, and that winds the ultra-quenching material scattered from the outer peripheral surface on the inner peripheral surface; And a winding means for winding the ultra-quenched material from the inner peripheral surface thereof.

Further, according to the present invention, there is provided a super-quenching material winding device characterized in that the inner peripheral surface is formed in a shape capable of holding a coolant by centrifugal force.

Further, according to the present invention, there is provided a method of using the above-described ultra-quench material winding device, wherein a coolant is retained on the inner peripheral surface by centrifugal force, and the ultra-quenched material scattered from the outer peripheral surface, There is provided a method of using a super-quenching material winding device, characterized in that winding is performed while promoting cooling on the inner peripheral surface.

Further, according to the present invention, the cooling agent includes a rust preventive material, and at the same time that the super-quenched material scattered from the outer peripheral surface is wound on the inner peripheral surface, a rust preventive treatment is performed. A method of using the ultra-quenched material winding device is obtained.

Further, according to the present invention, the inner peripheral surface has a double structure composed of a first wall surface and a second wall surface surrounding the first wall surface, and a passage hole is provided in the first wall surface. , Passing the coolant from the first wall surface to the second wall surface by centrifugal force through the passage hole to separate the coolant from the ultra-quenched material wound on the inner peripheral surface. An ultra-quenched material winding device characterized by the above is obtained.

In other words, the present invention, in the production of quenched ribbons and quenched wire rods, melted alloy melted in a high frequency coil or the like is sprayed toward the cooling roll with Ar gas or the like to be rapidly solidified into ribbons or wire rods, This ribbon or wire is received by the inner peripheral surface of the rotating drum coaxial with the cooling roll, and further held by this inner peripheral surface by centrifugal force.After that, the cooling roll is removed and used as a reel for winding instead. It is configured to receive a ribbon or a wire and is characterized in that the ribbon or the wire is wound without being separated.

In addition, in the rotating drum, a liquid layer of cooling liquid or rust preventive oil is formed by centrifugal force to accelerate the cooling of the melt or to discharge the hot melt, and at the same time to put a thin strip or wire into the rust preventive oil to prevent oxidation. And

The inner peripheral surface of the rotating drum is divided into two parts, the first wall surface and the second wall surface.
It is also possible to have a heavy structure and to form the first wall surface side with a rope or a porous plate so as to be dehydrated and removed after the above-mentioned treatment.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 (a) to (c) show the principle configuration of the winding device,
The winding process is shown in FIGS. 2 (a) to (d).

1 is a cooling roll, 2 is a coil for high frequency induction heating, 3 is a crucible with an alloy melting nozzle, 4 is a melting raw material or molten metal, 5
Is a rotary drum arranged coaxially with the cooling roll 1 and having an inner peripheral surface formed so as to be able to retain cooling water or rust preventive oil by centrifugal force, and 6 is arranged on the inner wall surface of the rotary drum 5. A punching plate, 7 is rust preventive oil for cooling water, 8 is a winding reel whose radius can be varied, and 9 is a thin strip which is melted and rapidly cooled by the cooling roll 1. As described above, the punching plate 6 is arranged on the inner wall surface of the rotating drum 5, and thus the inner peripheral surface of the rotating drum 5 is formed into the first wall surface (the wall surface of the punching plate 6) and the second wall surface. It has a double structure of the wall surface (inner wall surface of the rotating drum 5).

Now, rotate the cooling roll 1 and adjust the rotation speed of the rotating drum 5 so that the peripheral speed becomes the same as the peripheral speed, and rotate in the same direction. Then, water is applied to the wall of the rotating drum 5. Water was poured to make a rotating liquid layer.

As shown in FIG. 1 (c), the crucible 3 with a nozzle is
An alloy for obtaining a ribbon is put, the alloy is heated and melted by the high frequency induction coil 2, and the molten metal is pressurized and sprayed toward the cooling roll 1 by Ar gas, and the molten metal is rapidly cooled and solidified by the cooling roll 1. Rotating drum 5 consisting of thin plate 9
Of the rotating drum 5, which hits the cooling water 7 rotating on the inner peripheral surface of the rotating drum 5 and is further cooled and is pressed against the inner peripheral surface of the rotating drum 5 by the centrifugal force to continue the rotation (FIG. 2). (See (a)).

Next, the cooling drum 1 is pulled out while the rotating drum 5 continues to rotate (see FIG. 2 (b)).

After the cooling roll 1 has been wiped, the winding reel 8 shown in FIG. 1 (b) is inserted, and rotation is performed in synchronization with the rotary drum 5 (see FIG. 2 (c)). The liquid layer on the inner peripheral surface of the rotary drum 5 is removed by suctioning and applying a centrifugal force of a predetermined value or more, and the rotary drum 5 and the winding frame 8 are synchronously decelerated and finally stopped. After winding the wire rod, reel 8
Reduces the radius and pulls it out from the rotary drum 5, and finishes the winding process (see FIG. 2 (d)).

In this embodiment, cooling water or rust preventive oil was used in the winding step, but it is of course possible to use neither cooling water nor rust preventive oil in the rotary drum.

[Advantages of the Invention] Conventionally, winding of a wire rod manufactured by this type of method for manufacturing a quenched ribbon or a quenched wire rod is performed by injecting a wire rod or pressure applied to a roll,
Since the flight angle is extremely changed by changing manufacturing conditions such as rotation, it is difficult to continuously perform winding at the same time as jetting, and the device is large-scale.

However, the present invention has a simple structure and can be wound without any problem even if the manufacturing conditions are changed. Moreover, the cooling water drum not only accelerates the cooling of things that do not completely solidify until a certain distance after injection, but also uses a rust preventive agent to perform rust preventive treatment after winding once. Since it is processed at one time, it is possible to significantly reduce the number of winding steps and rustproofing.
