関し、とくに占積率の有利な向上を図ったものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an amorphous alloy ribbon for a magnetic core, which is suitable for use as a magnetic core, i.e., the iron core of a transformer, and a method for manufacturing the same. This is an advantageous improvement.

て製造される。(Prior art) Amorphous alloys, especially Pa-based amorphous alloys with excellent magnetic properties, are seen as promising magnetic core materials for transformers, etc., and have recently been put into practical use, with field tests being conducted for use in power distribution transformers. It is at the stage immediately before. ``Such an amorphous alloy is disclosed in Japanese Patent Application Laid-Open No. 54-148122.
There are Fe-3i-B alloys, such as those disclosed in Japanese Patent No. 55-94460. It is manufactured by a so-called rapid solidification method in which it is cooled into a thin ribbon.
（発明が解決しようとする問題点）
ところでかような方法で製造された板を用いてトランス
磁心を作製したときの欠点の１つとして、積層した場合
における占積率の低下が挙げられる。(Problems to be Solved by the Invention) One of the drawbacks of producing a transformer core using plates manufactured by such a method is a decrease in space factor when laminated.
今まで試作されたトランスの占積率は７８〜８５％であ
り、従来のけい素鋼板を用いた場合のそれが９８％前後
であるのと比べると大幅に劣る。The space factor of the transformers prototyped so far is 78 to 85%, which is significantly inferior to the 98% or so obtained when conventional silicon steel plates are used.
かかる占積率の低下は、磁心において同一の磁気回路的
効果を得ようとする場合に、磁心の体積を増加せざるを
得ないという弊害を招いていた。Such a decrease in the space factor has caused the disadvantage that the volume of the magnetic core must be increased if the same magnetic circuit effect is to be obtained in the magnetic core.
また占積率の低下は、表面あらさが大きいことがその一
因であるが、表面あらさが大きいと板同志の接触が不均
一となって接触部の接触電気抵抗が増大するため、そこ
に熱が集中し、磁心を破損するおそれもあった。In addition, one of the reasons for the decrease in the space factor is the large surface roughness, but when the surface roughness is large, the contact between the plates becomes uneven and the electrical contact resistance of the contact area increases, so heat is generated there. There was also a risk that the particles would concentrate and damage the magnetic core.

５％の占積率を実現したのである。Therefore, in this invention, a trace amount of an element that improves the workability is added to the Fe-5t-83 element alloy to improve the workability, and then surface smoothing treatment is performed to improve the workability of the Fe-5t-83 element alloy.
They achieved a occupancy rate of 5%.

This is a method for producing quality alloy ribbon.
以下この発明を具体的に説明する。This invention will be specifically explained below.
まずこの発明において成分組成を上記の範囲に限定した
理由について説明する。First, the reason why the component composition is limited to the above range in this invention will be explained.
Ｂ：５〜２０％
Ｂ含有量が５％に満たなかったり２０％を超えたりする

〜２０％の範囲に限定した。B: 5-20% If the B content is less than 5% or exceeds 20%, it will be extremely difficult to form an amorphous alloy at room temperature.
It was limited to a range of ~20%.
Ｓｉ：５〜２０％

は５〜２０％の範囲に限定した。Si: 5-20% If the Si content is less than 5%, excellent magnetic properties cannot be obtained when forming an amorphous alloy, while if it exceeds 20%, it becomes difficult to form an amorphous alloy, and Since the saturation magnetic flux density decreases even if an amorphous alloy is formed, the Si content is limited to a range of 5 to 20%.
記号Ｍで示したＣｒ、Ｍｏ、Ｔａ、Ｍｎ、Ｎｉ。Cr, Mo, Ta, Mn, and Ni indicated by the symbol M.

飽和磁束密度を低下させ、磁心材料として不適当になる
ので添加量は０．０５〜５％の範囲に限定した。Co, V, Nb, and W are all elements that improve workability. However, when each of the above elements is used alone or in combination,
If the amount added is less than 0.05%, no significant effect on rolling will be obtained, while if it is more than 5%, it will reduce the saturation magnetic flux density, apart from the workability, making it unsuitable as a magnetic core material, so the amount added is 0. It was limited to a range of .05 to 5%.
上記のような好適成分組成に調製した合金溶湯から、急
冷凝固法によって非晶質合金薄帯を作製するのであるが
、急冷凝固ままの薄帯の表面は荒れているため、そのま
までは十分満足のいく鉄損特性は得られない。An amorphous alloy ribbon is produced by a rapid solidification method from a molten alloy prepared to have a suitable composition as described above, but since the surface of the ribbon as rapidly solidified is rough, it is not completely satisfactory as it is. It is not possible to obtain good iron loss characteristics.

It is finished to be less than m.

表面平滑化処理としては、冷間や温間における軽圧延処

で、３００℃以下の温度域で処理する必要がある。When adjusting the surface roughness by warm rolling, if the processing temperature exceeds 300°C, some alloy components may crystallize and the original excellent magnetic properties may not be obtained, so the treatment temperature should not exceed 300°C. It is necessary to process in a temperature range of
