表面をもつことが要求される。The technology for producing ultra-quenched ribbons using the single roll method has made significant progress, and has recently been applied to the production of amorphous magnetic alloy ribbons used as materials for fB magnetic heads, high-frequency transformer cores, and the like. A ribbon of such an amorphous magnetic alloy is required not only to have good magnetic properties but also to have a smooth surface of good quality.

なる。In the case of the conventional general amorphous alloy ribbon manufacturing method,
The angle θ (θ is the angle with respect to the normal direction of the surface of the moving cooling body) at which the molten metal is jetted from the spout part of the molten metal supply pipe to the surface of the moving cooling body is a right angle or almost a right angle (%
-46845). Or 70° to 10° with respect to the moving direction of the moving cooling body (Japanese Patent Laid-Open No. 59-183
The molten metal ejected at the ejection angle θ of the method disclosed in Japanese Patent Publication No. 957 forms a puddle on the surface of the cooling body. The hot water tank is immediately cooled at a rate of 104°C/8e0 or more and becomes a thin ribbon.

移動し。In particular, a smooth ribbon can be obtained by setting the ejection angle in the same direction as the moving direction of the moving cooling body (for example, a rotating roll), while a smooth ribbon can be obtained by ejecting the molten metal in the opposite direction and forming it on the surface of the moving cooling body. The molten metal may be turbulent and the molten metal may scatter in a direction different from the moving direction of the moving cooling body. Momentum is imparted to the molten metal particles, and a portion of the molten metal particles once again moves toward the spout.

も不可能にもなる。The experiment of manufacturing a ribbon by spouting molten metal in the opposite direction to the moving direction of the moving cooling body described in JP-A-58-16760 was repeated, and the experiment was published in JP-A-59-1839.
As stated in Publication No. 57, when molten metal is jetted out against a moving cooling body that is moving at high speed, it is generally difficult to form a stable pool on the surface of the moving cooling body. This was confirmed experimentally. JP-A-57-1
No. 95564 and Japanese Unexamined Patent Application Publication No. 16760/1982 describe manufacturing conditions other than ejecting the molten metal in the opposite direction (the shape of the spout, the gap between the tip of the spout and the surface of the movable cooling body, the shape of the movable cooling body) There is no mention of movement speed, etc.). However, these conditions make the production of ribbons both possible and impossible.

術を提供する事にある。The present inventors have found that when spouting molten metal in the opposite direction to the moving direction of the moving cooling body, it is extremely important to It has been found that it is difficult to complete an apparatus for producing an amorphous ribbon unless strict conditions are added.That is, one object of the present invention is to determine the above-mentioned manufacturing conditions for producing an amorphous ribbon by the reverse injection method. Under these conditions, the present invention aims to provide a technology for manufacturing an amorphous ribbon in which molten metal is ejected in a direction opposite to the moving direction of a moving cooling body.

造方法において。According to the present invention, there is provided a method for producing an amorphous metal ribbon by spouting a molten metal from a spout part of a molten metal supply pipe to a moving cooling body, and rapidly cooling and solidifying the molten metal, comprising:
In the method for manufacturing an amorphous metal ribbon, the molten metal is jetted onto the surface of the moving cooling body in a direction opposite to the traveling direction of the moving cooling body.

Then, the relationship that the length a of the rear lip in the direction opposite to the traveling direction is at least larger than dtanθ is satisfied, and d is within the range of 0.01■≦d (0.6 mm). Furthermore, there is obtained a method for manufacturing an amorphous metal ribbon, characterized in that the rear lip is disposed substantially parallel to the surface of the moving cooling body.
以下憩日 〔実施例〕 次に本発明の実施例について図面を参照して説明する。The following rest days 〔Example〕 Next, embodiments of the present invention will be described with reference to the drawings.

同一方向の場合、噴出溶湯の流速は移動冷却体に近づく
につれて２次第に加速される。従って冷却体表面で形成
される湯溜シは安定する事なく、複雑な流速変化を受け
つつ凝固され。In the case of the conventional manufacturing method (forward jet method) shown in Fig. 2, that is, when the jetting direction of the molten metal 2 is always the same as the moving direction of the moving cooling body 3, the flow velocity of the jetting molten metal increases as it approaches the moving cooling body. 2 It will be accelerated gradually. Therefore, the molten water formed on the surface of the cooling body is not stabilized and solidifies while undergoing complicated changes in flow velocity.
移動冷却体の移動速度でもって搬送される。流速が加速

凸凹を生ずしめる。It is conveyed at the moving speed of the moving cooling body. When the flow rate is accelerated, atmospheric gas or air that adheres to the surface of the moving cooling body is drawn in, and when it expands and scatters, it causes unevenness on the surface of the ribbon.

速度と等しい速度でもって移動を開始する。On the other hand, in the case of the reverse injection method according to the present invention shown in FIG. 1, the molten metal 2 is ejected in the opposite direction to the moving cooling body 3, so it approaches the surface of the moving cooling body. The flow velocity is gradually reduced due to the load resistance of the moving cooling body, which is different from the case of the above-mentioned sequential jetting method, and the flow velocity reaches zero near the position where the pool is formed. It will have a velocity vector in the same direction as . Eventually, the sump 2' solidifies on the surface of the moving cooling body and starts moving at a speed equal to the moving speed of the moving cooling body.
上記の場合、噴出湯が逆噴出されるための負荷抵抗に対
して、湯溜シを安定に静止させ更に逆方向に搬送させる
ための条件を整えねばならない。In the above case, it is necessary to prepare conditions for stably stopping the hot water tank and transporting it in the reverse direction against the load resistance for the hot water to be jetted out in the opposite direction.

The failure of the reverse jetting method described in Publication No. 4 and Japanese Patent Application Laid-Open No. 58-16764 was due to errors in other setting conditions, not just the molten metal jetting angle θ. it is conceivable that.

小さくする事を試みた。The present inventors first made the rear lip ff at the tip of the jet nozzle part, which is closer to the rear with respect to the traveling direction of the moving cooling body 3, longer than the front lip f1, which is closer to the front, and the gaps d and e with the respective moving cooling bodies. We tried to establish the relationship d≦e between the two and to make d as small as possible.

移動冷却体と噴出口部との相対移動速度と溶湯の噴出角
度との明白な相関関係は見られなかった。There was no obvious correlation between the relative movement speed between the moving cooling body and the spout and the spout angle of the molten metal.
噴出角度が大きくなる場合、該移動速度を下げた方が薄
帯製造の成功率は高くなる。When the ejection angle becomes large, the success rate of ribbon production becomes higher if the moving speed is lowered.
本発明の逆噴出方式によって製造される薄帯は従来の順
噴出方式によって得られる薄帯よりも。The ribbon produced by the reverse jetting method of the present invention is superior to the ribbon produced by the conventional forward jetting method.

を下げる事によって制御可能である。You can get a thinner one. Therefore, depending on the conditions, the ribbon may have a network of holes. This is because the amount of molten metal ejected per unit time is insufficient, and can be controlled by lowering the relative movement speed.

現可能な領域である。It is desirable that the pool formed on the surface of the moving cooling body be uniform both in quantity and temperature. In order to make the temperature distribution of the hot water pool uniform, it is generally desirable to make the width of the spout groove as narrow as possible. However, if the spout groove gb becomes smaller, the jet pressure P2 must be increased, and the molten metal supply pipe,
Problems arise in the mechanical strength of the jet nozzle, control of the jet flow velocity under high pressure, etc., and there is a natural limit to the narrowing of the jet nozzle groove width. According to the experimental results, b=0.1~0
．． It was possible to manufacture a ribbon with a thickness of 6 mm. Especially b=
Stable ribbon production was possible at 0.1 to 0.3H. In this case, when b > 0.6 m, the ejection pressure P is such that the molten metal easily ejects from the ejection port and creates a stable ribbon.
8 becomes difficult to control. Even if the groove width is 0.01≦b<0.1 and 0.6 pb≦1 (hu), the ejection pressure P in the molten metal supply pipe remains constant. This is an area that can be fully realized by improving the sophistication of the control mechanism.

最適製造条件とその製品薄帯評価をまとめて示す。15.20.The optimal manufacturing conditions at 30, 40, 50, 60, and 70 degrees and the evaluation of the product ribbon are summarized.

帯の板厚は次第に薄くなシ、その断面の平行度δもまた
急激に小さくなる。As is clear from this figure, as θ increases, the thickness of the ribbon gradually decreases, and the parallelism δ of its cross section also decreases rapidly.
上述の結果は最適条件下に於ける薄帯製造評価であるが
、その条件が適切でないと溶湯の飛散の生ずる場合もあ
る。The above results are evaluations of ribbon production under optimal conditions, but if the conditions are not appropriate, molten metal may scatter.

が６０°を越える場合には、均一な薄帯を得ることは困
難であった。As θ becomes larger, it becomes difficult to control the molten metal jetting pressure P2 and the moving speed υ of the moving cooling body, and it is difficult to obtain a uniform ribbon especially when the molten metal jetting angle exceeds 60°.

、込みは少く、滑らかなものであった。As shown in Figure 5 above, the ribbon manufactured by the molten metal jetting pressure under sufficient control of the manufacturing conditions is different from the ribbon manufactured by the forward jetting method (currently, most manufacturing uses this method). Even when produced in the atmosphere, there was little gas entrainment and entrainment, and the product was smooth.

The molten metal of 3Mo, 5(stn)2z alloy was jetted onto the surface of the cooling roll, and the plate width was 30 and the plate thickness was 0.02 to 0.0158.
A thin ribbon was made. The crystal structure of this ribbon was examined by X-ray diffraction, and it was confirmed that it was amorphous from an X-ray perspective.
