As shown in the figure and the schematic diagram of FIG. 2, the raw metal 2 charged into the molten metal supply pipe 1 is heated and melted in the heating furnace 4 directly above the molten metal spouting nozzle 3, and then an air piston or the like (not shown) is used. The molten metal supply pipe 1 is lowered to just below the surface of the rotary cooling body 5, and an inert gas such as argon is added at high pressure to the molten metal 2' in the molten metal supply pipe 1, and the molten metal 2' is directed toward the rotary cooling body. , eject and solidify to produce a metal ribbon. In order to prevent the raw metal 2 from oxidizing due to heating, an inert gas such as argon gas is constantly fed into the molten metal supply pipe 1 at low pressure. Here, when melting the raw metal, a heat-resistant plate 8 having porous holes is provided for the following reason. As a result, the distance between the molten metal and the tip of the nozzle increases, leading to a drop in the temperature of the molten metal when it is spouted.

ズル３においては原料金属２が溶は始めるとその溶融金
属２′によってノズル３が塞がれる。Further, in the molten metal spouting nozzle 3 disposed coaxially with the molten metal supply pipe 1, when the raw metal 2 starts to melt, the nozzle 3 is blocked by the molten metal 2'.
そのためにノズル３まで流れず先端部の溶融金属はノズ
ルより流入した空気と接触することになる。Therefore, the molten metal does not flow to the nozzle 3 and the molten metal at the tip comes into contact with the air flowing in from the nozzle.
従っテ鉄、アルミニューム、ジルコンなど酸化し易い原
料金属の溶湯はノズル先端部で酸化され。Therefore, molten raw metals that are easily oxidized, such as iron, aluminum, and zircon, are oxidized at the nozzle tip.
溶湯の底部に酸化被膜６が形成される。前記の様な状態
でノズルから溶融金属が噴出される場合。An oxide film 6 is formed on the bottom of the molten metal. When molten metal is spouted from the nozzle under the conditions described above.
該酸化被膜６はノズルスリット間に引っ掛かり。The oxide film 6 gets caught between the nozzle slits.

酸化被膜が耐熱板よりノズルへ流出しない様にした。Causes clogging. As a result, cracks occur at the tip of the molten metal jet, and cracks and holes occur in the produced metal ribbon, making it impossible to produce wide strips. In order to eliminate this defect, the applicant of the present application previously made an invention as disclosed in Japanese Patent Publication No. 57-54227, ``Method and Apparatus for Manufacturing Wide Amorphous Metal Tape''. That is, a heat-resistant plate having a large number of holes was disposed between the molten metal supply pipe and the molten metal spouting nozzle, and this served as an R material to prevent the oxide film from flowing out from the heat-resistant plate to the nozzle.

、これは積極的な酸化防止策とはならない。As a result, only the molten metal passed through the heat-resistant plate (P material) and a stable molten metal jet stream was ejected from the nozzle tip. However, there are strongly oxidizing substances in the molten metal (
For example, if Ti + Zr, etc.) are added, it becomes difficult to prevent the above-mentioned oxide film on the air contact surface. Moreover, this is not a positive oxidation prevention measure.

属広幅薄帯を提供する。(3) Problems to be Solved by the Invention The present invention uses a liquid ultra-quenching method to produce metal ribbon, which is comprised of a rotary cooling body, a molten metal supply pipe equipped with a spout nozzle, and a heating furnace. In the device, a heat-resistant plate (P material) having a large number of holes is arranged directly above the molten metal spouting nozzle in the molten metal supply pipe, and further, the arrangement of the heat-resistant plate when raw metal is melted on the heat-resistant plate (P material). In order to prevent the temperature drop at the nozzle tip and the formation of an oxide film on the bottom of the molten metal due to air inflow, the carbon ring is placed under the heat-resistant plate so that it does not come into direct contact with the raw metal or the molten metal supply pipe. This method involves heating ultra-quenched metal ribbon in argon gas at the same time as the raw material metal, and a stable molten metal jet is ejected from a jet nozzle to produce a homogeneous and high-quality wide metal ribbon. provide.
（４）問題点を解決するための手段

が耐熱板下に配設される。(4) Means for Solving Problems As shown in FIG. 1, the metal ribbon manufacturing apparatus used in the present invention has a large number of holes directly above the nozzle 3 when melting the raw metal in the molten metal supply pipe 1. A heat-resistant plate 8 having the same structure is provided as a P material. Further, a carbon ring is provided under the heat-resistant plate as a getter material to prevent the temperature from decreasing from the bottom of the heat-resistant plate to the tip of the nozzle and to prevent the formation of an oxide film on the molten metal due to air flowing in from the tip of the nozzle.
該炭素環は溶融金属や炭素と反応する材質からなる溶融
供給管などに直接接触することを避けねばならない。The carbon ring must be prevented from coming into direct contact with a melt supply pipe made of a material that reacts with molten metal and carbon.
耐熱板の孔は溶融金属がそれ自体の表面張力で保持され
る程度の大きさであればよい。The holes in the heat-resistant plate need only be large enough to hold the molten metal by its own surface tension.
原料金属とゲッタ材としての炭素環とがアルゴンガス中
で同時に加熱されるときノズル先端から流入する空気は
上部から流しているアルゴンガス熱され混入する空気中
の酸素７炭酸ガスとする。When the raw material metal and the carbon ring as the getter material are heated simultaneously in argon gas, the air flowing in from the nozzle tip is heated by the argon gas flowing from the top, and the mixed air becomes oxygen and carbon dioxide.
その炭酸ガスは耐熱材（Ｐ材）とノズル先端までの空間

して外部へ流出する。ノズル先端から流入する空気中の
酸素は溶融金属に接触する前にゲッター材と燃焼反応し
、炭酸ガスとなり溶融金属の酸化被膜生成を防ぐことが
出来る。The carbon dioxide gas fills the space between the heat-resistant material (P material) and the nozzle tip. Furthermore, the excess carbon dioxide gas generated flows out through the nozzle. The oxygen in the air flowing in from the nozzle tip undergoes a combustion reaction with the getter material before coming into contact with the molten metal, and becomes carbon dioxide gas, which can prevent the formation of an oxide film on the molten metal.
（５）作用
以上の様にゲッターとして炭素環を耐熱板（Ｆ材）の下

溶融金属を円滑な渦流れの下に。(5) Function As described above, by arranging the carbon ring as a getter under the heat-resistant plate (F material), the molten metal can flow under a smooth swirl without clogging the nozzle.
ノズルの先端から冷却回転に向けて噴出させることが出
来る。It can be ejected from the tip of the nozzle toward the cooling rotation.

とき溶融金属の噴出状況は極めて滑らかであった。After the raw metal is completely melted, the supply pipe 1 is lowered and the nozzle 3 is placed at a predetermined position opposing the rotary cooling body 5 (the gap between the circumferential surface of the rotary cooling body 5 and the nozzle tip is approximately 0).

った。またゲッター用の炭素環の消耗は稀かであった。Note that all the slag (slag) 6 was caught on the heat-resistant plate (P material) used after manufacturing the wide amorphous alloy ribbon, and almost no stains due to the slag from the shinozzle were observed. In addition, consumption of the carbon ring for the getter was rare.

ノズルの目詰まりの直接原因とはならない。The slag 7 caught on the heat-resistant plate is an oxide generated when the raw metal is heated. In the molten state, this floats to the top of the molten metal and is not a direct cause of nozzle clogging during the production of wide ribbons.

ど完全な広幅薄帯とはならなかった。As a result of investigating the number of times the nozzle can be used using the same manufacturing method as above with a raw material metal having the same component composition as above, it was found that even if Zr-added molten metal, which is easily oxidized, was blown out 10 times using the same nozzle, the quality remained stable and of good quality. It was possible to make wide amorphous alloy thin strips. However, the heat-resistant plate (P material) gets dirty with slag, so it has to be removed and washed every few times. No. The carbon ring was hardly consumed and could be used ten times. Of course, if the carbon ring for the starter is not used to protect the tip of the nozzle from the oxidizing atmosphere, the jet flow from the nozzle will be unstable and sloppy when molten metal, especially metals that are easily oxidized such as Zr, are contained. (Slag) 4 caused cracks and holes due to clogging of the slits, and an almost perfect wide ribbon was not obtained.
