て有望視されている。2. Description of the Related Art Conventionally, various means have been disclosed for continuously producing a ribbon from a molten metal. However, in any case, molten metal is melted at a predetermined pressure from a nozzle having an opening of a predetermined shape. A continuous ribbon is formed by collision solidification on the cooling substrate facing the nozzle opening. As a concrete means for producing a wide metal ribbon, for example, Japanese Patent Application Laid-Open No. 53-535.
There is a method described in Japanese Patent No. 25, the outline of which is a slit nozzle having a rectangular opening and cooling substrates (rolls or belts) facing each other at intervals of 0.03 to 1 mm, and cooling substrates of 100 to 2000 m / It moves at the speed of a minute, sends the molten metal from the slit nozzle to the surface of the cooling substrate,
This is a method for producing a metal ribbon by thermally contacting and rapidly solidifying. The metal ribbon produced by such a method exhibits various excellent characteristics.For example, an amorphous ribbon of an iron-based alloy is regarded as a promising material for iron cores of power transformers due to its excellent magnetic characteristics. There is.

になった。The metal ribbon obtained by this method generally has a thin plate thickness of about 30 μm at most, and thus has a problem in being used as an industrial material. For example, when it is used as a material for a power transformer core, the number of windings becomes large when manufacturing a core by winding a thin strip, and the process becomes complicated. As a countermeasure, the applicant of the present invention has disclosed, for example, in JP-A-60-108144.
In the publication, a method for producing a thick metal ribbon by using a multiple slit nozzle having a plurality of parallel openings to perform rapid solidification on a moving cooling substrate was proposed. By this method, it became possible to manufacture a metal ribbon having a plate thickness of 50 μm or more.

することである。However, in order to stably produce a thick ribbon industrially by the method disclosed in JP-A-60-108144, it is necessary to further improve the following points. That is, for example, with this method,
In order to manufacture a thin ribbon having a thickness of m or more, the number of nozzle openings must be 3 or more, and the intervals between the nozzle openings must be plural. When producing a small amount in a short time casting, a very good thin strip can be obtained, but since the interval of the nozzle opening must be generally thin, when casting for a long time using a nozzle with multiple intervals, this nozzle Occasionally, the gap between the openings may be damaged or bent, and the ribbon may break during casting, interrupting the casting, or even if the casting can be completed, the thickness of the ribbon is not uniform in the width direction. Occasionally it became uniform. An object of the present invention is to provide a method for suppressing such troubles that occur during casting and stably producing a thick metal ribbon for a long time on an industrial scale.

Further, in a nozzle having two openings (hereinafter referred to as a double slit nozzle), the length of each opening in the cooling substrate moving direction is 0.8.
It has been found that it is possible to manufacture a thick ribbon having a thickness of 50 μm or more if the thickness exceeds mm, and the inventors have invented a method for stably producing a thick ribbon on an industrial scale.

That is, the nozzle 1 is composed of two openings 2 and 2 ', which are parallel to each other, have the same length in the longitudinal direction, and are arranged substantially at right angles to the moving direction of the cooling substrate. .

In FIG. 1, when the number of nozzle openings is two (in the case of the method of the present invention) and one, the length of each opening in the cooling substrate moving direction (hereinafter referred to as opening width), the plate thickness of the ribbon, and The relationship with the plate thickness variation will be shown. In the case of the double slit nozzle, the plate thickness of the ribbon increases with the increase of the opening width, and when the opening width exceeds 0.8 mm, the plate thickness of the ribbon is stable at 50μ.

であることが望ましい。Furthermore, the variation in the thickness of the ribbon is 0.8 for the opening width.
When it exceeds mm, it is stably 10% or less. Therefore, the opening width of the double slit nozzle is set to more than 0.8 mm. This is because, when the thin strips are wound or laminated and used, the variation in the thickness of the thin strips used is preferably 10% or less in view of the space factor and the like.

The upper limit of the opening width of the double slit nozzle used in the method of the present invention was set to 2 mm.

The method disclosed in Japanese Patent No. 525, that is, the relationship between the opening width and the plate thickness of the ribbon and the plate thickness variation when the numerical aperture is set to 1 is also shown. Even if the width is increased, the plate thickness does not stably reach 50 μm or more, and the plate thickness variation is a value exceeding 10%.
The distance between the two openings (indicated by d in FIG. 3) is determined by the opening width of each opening, the distance between the nozzle opening and the cooling substrate, the ejection pressure of the molten metal, the moving direction of the cooling substrate, and the like. However, it is usually in the range of 0.2 to 4 mm.

帯である。It can be seen from FIG. 1 as an experimental result that the variation of the strip thickness of the ribbon is improved by setting the number of the nozzles to be two. The effect on thickness variation is considered as follows. FIG. 4 is a schematic diagram showing an example of the present invention, and 3 is a roll or belt-shaped cooling substrate, which moves in the direction of the arrow. A crucible 4 has a double slit nozzle 1 at the bottom and holds a molten metal 5 inside. The crucible 4 and the nozzle 1 may be provided separately. 6,
Reference numeral 6'denotes a molten metal reservoir (hereinafter referred to as paddle) formed by the molten metal 5 flowing out from the openings 2 and 2 ', and 7 a manufactured ribbon.

好となる。When casting is performed using a double slit nozzle, two paddles are formed as shown in FIG.
It is considered that the second paddle (for example, 6'in FIG. 4) contributes to the improvement of the strip thickness variation. That is, FIG. 2 schematically shows a view when these paddles are viewed from the rear in the cooling substrate moving direction.
And 8'are ribbons formed at 6 and 6'in FIG. 4, respectively. For example, even if the surface of the thin strip 8 formed by the first paddle 6 has unevenness as shown by the dotted line (even if the plate thickness varies), molten metal will not flow from the next second opening. Since the paddles 6'are formed so as to alleviate this unevenness and the paddles 6'are formed, the resulting ribbon 7 has a good thickness variation.

The molten metal 5 is caused to flow out onto the cooling substrate 3 which is moving to the first opening 2. However, the molten metal 5 is drawn out from the paddle 6 formed on the cooling substrate 3 through the first opening 2 and is discharged from the second opening 2 '. A paddle 6 ′ is formed by the molten metal 5 that has flowed out, the ribbon is pressed to enhance the thermal contact between the ribbon and the cooling substrate 3, and the ribbon made from the paddle 6 ′ is polymerized and finally thickened. Obtain the ribbon 7.

く述べる。At this time, since the nozzle has two openings, the effect of increasing the thickness of the ribbon is smaller than that when three or more openings are provided, but the length of each opening in the cooling substrate moving direction is reduced. If it exceeds 0.8 mm, the lengths of the paddles 6 and 6'in the moving direction of the cooling substrate become long, and the thickness of the thin strip exceeds 50 μm. Here, the lengths of the respective openings of the double slit nozzle in the cooling substrate moving direction may take the same value in the range of more than 0.8 mm and 2.0 mm or less,
Also, different values may be taken. On the other hand, since the strip width is determined by the lengths of the two openings in the longitudinal direction (indicated by L in FIG. 3), this length can be selected as appropriate according to the desired strip width. Good. The appropriate conditions for other manufacturing factors in the method of the present invention will be described in detail in Examples.
