【発明の詳細な説明】
従来、付加価値の高い方向性珪素鋼板の製造には、各種
圧延工程などの多くの工程が必要であり、それには多大
のエネルギー消費が伴う。DETAILED DESCRIPTION OF THE INVENTION Conventionally, the production of grain-oriented silicon steel sheets with high added value requires many processes such as various rolling processes, which involve a large amount of energy consumption.
最近、金属合金溶湯を急冷して、直接高付加価値(磁気
特性の良い等)の金属合金を得ようとする努力がなされ
、電子機器用あるいは電力機器用トランス鉄芯用などの
目的に沿う特性を有する合金が得られつつある。Recently, efforts have been made to rapidly cool molten metal alloys to directly obtain metal alloys with high added value (such as good magnetic properties), which have properties that meet purposes such as transformer cores for electronic equipment or power equipment. Alloys with
一般に行なわれている急冷法としては、第1図に示すよ
うに、回転円柱1に高温合金溶湯3をルツボ2の***ま
たはスリットを有するノズル4から打出して回転円柱1
の面上で急冷して帯状の金属合金5を得るものが多い。As shown in FIG. 1, a commonly used quenching method involves ejecting high-temperature alloy molten metal 3 onto a rotating cylinder 1 from a nozzle 4 having a small hole or slit in a crucible 2.
In many cases, a band-shaped metal alloy 5 is obtained by rapid cooling on the surface of the metal alloy.
しかしこの急冷法には次のような欠点が存在する。However, this rapid cooling method has the following drawbacks.
(1)大気中に高温状態で噴出するため、金属合金表面
が酸化されるなど、材料変質を起こしやす10
(2)噴出ノズルは高温溶湯が高速で通過するため常に
高温に保たれ、さらに大気雰囲気との界面であるため焼
結などの変質変形を起しやすい。(1) Because it is ejected into the atmosphere at a high temperature, material deterioration, such as oxidation of the metal alloy surface, is likely to occur. Because it is at the interface with the atmosphere, alteration and deformation such as sintering is likely to occur.
(3)回転円柱も高温溶湯と直接接触するので、瞬間的
に高温となり、酸化変質などをうけやすい。(3) Since the rotating cylinder also comes into direct contact with the high-temperature molten metal, it becomes instantly hot and susceptible to oxidation and deterioration.
(4)急冷法は製造方法が簡単である一方、製造工程で
の調整が困難である。(4) Although the rapid cooling method is a simple manufacturing method, it is difficult to adjust the manufacturing process.
本発明は以上のような欠点を除去し、より均一な鉄芯用
等の帯状急冷合金を製造することを目的とする。The present invention aims to eliminate the above-mentioned drawbacks and to produce a more uniform strip-shaped rapidly solidified alloy for use in iron cores, etc.
以下本発明をその実施例を示す第2図を参考に詳述する
。The present invention will be described in detail below with reference to FIG. 2 showing an embodiment thereof.
第2図に示すように、直径100cfrLの回転円柱1
を600回転/分で回転させる。As shown in Fig. 2, a rotating cylinder 1 with a diameter of 100 cfrL
Rotate at 600 rpm.
回転円柱1の真上からその回転方向に15°移動した位
置に溶湯が接触するように、内部に32%Si含有鉄溶
湯(合金溶湯)3を含む石英のルツボ2の下部のノズル
4を配設し、このルツボ2の周囲にステンレス製の流体
導管6および7を配置したものである。A nozzle 4 at the bottom of a quartz crucible 2 containing 32% Si-containing molten iron (molten alloy) 3 is arranged so that the molten metal comes into contact with the rotating cylinder 1 at a position moved by 15° in the rotational direction from directly above it. The crucible 2 is equipped with stainless steel fluid conduits 6 and 7 arranged around the crucible 2.
そして内側の導管6から51/分のヘリウムガスを回転
円柱に、噴出溶湯と平行してその周囲に流し、導管7に
液体窒素を31/分で、ヘリウム流の外側に噴出させる
。Helium gas is then flowed from the inner conduit 6 at a rate of 51/min into the rotating cylinder around the rotating cylinder in parallel with the spouted molten metal, and liquid nitrogen is jetted through the conduit 7 at a rate of 31/min to the outside of the helium flow.
これらの流体導管6,7の端と回転円柱1の側面との距
離はり、5mrnである。The distance between the ends of these fluid conduits 6 and 7 and the side surface of the rotating cylinder 1 is 5 mrn.
以上の装置を用いると、均一で良好な特性を有する帯状
金属合金5が得られる。By using the above-described apparatus, a strip-shaped metal alloy 5 having uniform and good properties can be obtained.
このようにして得られた帯状金属合金は、通常の製法で
作成した合金帯にくらべ、その表面金属酸化物量が1/
10以下に制御できる。The thus obtained strip-shaped metal alloy has a surface metal oxide content that is 1/1 that of an alloy strip produced by a conventional manufacturing method.
It can be controlled to 10 or less.
また回転円柱の表面は均質な帯状合金製造のため、平滑
さを保つ必要があるが、本発明のものは酸化等の変化を
受ける率が少く、同時に液体窒素で常時冷却されるため
、その温度が制御され、従来の方法で用いる回転円柱の
15倍程度、同様な表面の荒れを生ずるのに時間を要す
る。In addition, the surface of the rotating cylinder must be kept smooth to produce a homogeneous strip-shaped alloy, but the surface of the rotating cylinder is less susceptible to changes such as oxidation, and at the same time, it is constantly cooled with liquid nitrogen, so the temperature It takes about 15 times longer to produce similar surface roughness than the rotating cylinder used in the conventional method.
また、ノズルの周囲雰囲気には、大気を含まないため長
時間同じ径を維持することができ、均一な帯状合金を供
給することができた。Furthermore, since the atmosphere around the nozzle does not contain air, it was possible to maintain the same diameter for a long time, and a uniform strip-shaped alloy could be supplied.
このように本発明の方法を用いると、帯状合金薄板をよ
り安定に均一の質で製造することができる。As described above, by using the method of the present invention, a strip-shaped alloy thin plate can be manufactured more stably and with uniform quality.
また同様の方法によって、ニッケル、コバルト等を主成
分とする帯状の各種合金の製造にも適用できる。The same method can also be applied to the production of various strip-shaped alloys containing nickel, cobalt, etc. as main components.

Even when using active gases such as inorganic and organic gases such as carbon monoxide, carbon dioxide, and methane, or a mixture of two or more of these gases, the manufacturing atmosphere is stable and it is possible to produce homogeneous products that suit the purpose. It is.
また、合金溶湯と大気との絶縁には不活性ガスが良いが
、合金溶湯との反応性を有する流体(CO等)を流し、
合金溶湯の成分を変化せしめる用途(浸炭など)にも適
用が可能である。Although inert gas is good for insulating the molten alloy from the atmosphere, it is also possible to flow a fluid (such as CO) that is reactive with the molten alloy.
It can also be applied to applications that change the composition of molten alloys (such as carburizing).
