る。 The injection nozzle in the present invention is for supplying molten metal to the surface of the cooling roll,
a molten metal storage section provided with the molten metal supply side open to the atmosphere and for temporarily storing the molten metal; and a molten metal provided in communication with the lower part of the molten metal storage section to supply the molten metal to the surface of the cooling roll. It consists of a molten metal spout for defining the flow cross section, shape, and flow rate of the molten metal. The injection nozzle extends through the outer wall of the main container, with the molten metal supply side of the molten metal storage section directed toward the outside of the main container, and the molten metal spout directed toward the inside of the main container. It is arranged at a predetermined distance from the surface of the cooling roll.

択される。 Here, the surface peripheral speed of the cooling roll is 10 to 80 m/
The reason for this is that if the speed is less than 10 m/s, the desired metal ribbon, etc. cannot be obtained, and if it exceeds 80 m/s, a metal ribbon, etc. of uniform quality cannot be obtained. It is from. This rotational speed is appropriately determined depending on the type of molten metal, the amount of feed, the distance between the molten metal spout and the rolls, etc. For example, when the molten metal is high alloy steel such as maraging steel, the speed is about 20 to 50 m/s, and when it is an Al-Al 2 O 3 composite material, it is 15 to 35 m/s.
When s is Al-Fe-Mo alloy, 50 to 75 m/
In the case of an iron-silicon-boron alloy, etc., the preferred rotational speed is about 30 to 60 m/s.

First, molten metal adjusted to a desired component ratio is supplied to the molten metal storage section of the injection nozzle. At this time, it is best to plug the molten metal spout to prevent molten metal from flowing into it. On the other hand, the exhaust means is operated to forcibly supply compressed fluid from the compressed fluid supply source to the exhaust section through the conduit, to forcibly exhaust the gas inside the main body container to the outside of the main body container, and to reduce the pressure inside the main body container. Also, the cooling roll is rotated at high speed. 10 to 80 m/s depending on desired reduced pressure state and type of molten metal
When the molten metal reaches the desired number of rotations of the rolls, the molten metal is guided to the molten metal spout, and the molten metal is sucked into the main container and comes into contact with the cooling roll. The molten metal is rapidly cooled by the cooling roll, which is controlled to rotate at a desired rotational speed within 10 to 80 m/s taking into account the type of molten metal, and is turned into a metal ribbon or the like by the rotation of the roll. These metal ribbons or thin pieces are carried by exhaust fluid directed from the inside of the main container to the outside of the main container formed by the exhaust means, and are continuously taken out of the main container from the metal ribbon extraction section. This allows continuous production of metal ribbons and the like.

With the apparatus of the invention, metal ribbons can be continuously produced and taken out. In addition, the rotation speed of the cooling roll is controlled at a speed that takes into account the type of molten metal, and the molten metal storage section is open to the atmosphere instead of the closed structure required for the injection nozzle to pressurize the molten metal. Therefore, molten metal can be replenished to the injection nozzle without interrupting operation, and metal ribbons and the like can be manufactured with high yield and uniform quality.

Embodiments of the exhaust system in the present invention include:
It is a fluid type and uses the suction effect of fluid.
A so-called aspirator type exhaust means can be used. As the fluid used here, compressed air, compressed gas such as nitrogen or argon, water, etc. can be used. This exhaust means communicates with the interior of the main container.

してもよい。 The shape of the cooling roll in the present invention is usually cylindrical, but it is not limited to this. You can stay there. In this case, the cooling conditions differ in the width direction of the metal ribbon, resulting in a composite material. The material for the cooling roll may be steel, copper, aluminum, or an alloy thereof, and may be appropriately determined depending on the type of molten metal, cooling conditions, etc. Further, the surface of the cooling roll that comes into contact with the molten metal may be treated with a hard coating such as hard chrome plating to prevent roughness.
また、冷却用ロールは、金属溶湯から熱を奪う

よい。 Furthermore, since the cooling roll removes heat from the molten metal, the temperature of the roll itself also increases. Therefore,
If the operation continues for a long time, the cooling conditions for the molten metal will change, which may change the quality of the product. In order to prevent this, heat may be taken out from the roll through the roll shaft to the outside of the main container and dissipated. A heat pipe may be used as a heat conductor.
