いた。The former one of the above-mentioned prior arts is a method of injecting fine molten metal droplets into an atmosphere gas. Therefore, the atmosphere gas is used as a refrigerant, so that the cooling capacity is reduced. There was a problem that was small. Therefore, in order to increase the cooling capacity, it is necessary to increase the flight distance of the metal droplets or to make the metal droplets as small as possible. There was a problem that it was necessary to speed up. Moreover, the metal powder produced under this conventional technique has a large surface area because of its fineness, which increases the danger of dust explosion and poses a safety problem.

が実情である。On the other hand, the latter of the above prior arts is
Although the cooling capacity can be improved by adopting the cooling base, there is a problem that the risk of dust explosion is rather increased because the manufactured metal powder is fine. Therefore, in order to eliminate the danger of dust explosion, it is indispensable to oxidize the surface of the metal powder and the handling of the manufactured powder and its handling are complicated. Of course, such a drawback can be avoided by producing coarse-grained metal powder or flake-shaped metal. However, in the case of this conventional technique, since the melting container (crucible) itself is rotated and jetted, the orifice shape of the nozzle cannot be increased (the leakage of the molten metal occurs), and the metal powder is not pulverized due to the structure. The reality is inevitable.

製造装置が有効であることが判った。That is, according to the present invention, the molten metal in the molten metal container held in an inert gas atmosphere is cooled by a rotary injection nozzle disposed in the lower portion of the molten metal container in a direction opposite to the rotation of the nozzle. When producing solidified metal by allowing it to flow down onto the board and quenching, the orifice diameter
A device equipped with a cooling plate and a concentric injection nozzle of 1.0 mm or more that rotates in the opposite directions.
While rotating at a speed of rpm, the molten metal is horizontally ejected by centrifugal force, and at the same time, it is collided with the inclined inner wall surface of the cooling plate that rotates in the opposite direction at a speed of 3000 to 7000 rpm, and the rapidly solidified metal is spread. A method for producing quenched metal flakes, characterized by obtaining flakes. In order to carry out the above method, the melting furnace is mainly arranged in the atmosphere adjusting chamber, a rotary injection nozzle for molten metal, and a cooling board rotating in the opposite direction to the nozzle are arranged in the apparatus. While attaching the pouring nozzle to the bottom of the furnace,
Immediately below this pouring nozzle, an injection nozzle formed by opening a plurality of orifices on the peripheral surface of the lower end is rotatably supported, and an inclined wall surface concentric with the rotation axis of the injection nozzle and facing the orifice. It has been found that a quenching metal flake manufacturing apparatus characterized by supporting a funnel-shaped rotating cooling plate having a rotator so as to be reversible is effective.

とにより金属融滴の冷却に必要な飛行距離を小さくする
ことができるので装置の小型化が図れる。The principle of the present invention is based on the fact that the molten metal held in the rotating injection nozzle is ejected as a molten droplet from the orifice by centrifugal force, and at the same time, the molten metal collides against the inclined inner wall surface of the rotating cooling plate. Then, the molten metal is ultra-quenched and solidified to obtain a flake-shaped quenched metal. As described above, by using the cooling plate as the quenching means, the flight distance required for cooling the metal melt droplets can be shortened, so that the apparatus can be downsized.

らである。Further, in the present invention, by maintaining the respective rotation speeds of the rotary injection nozzle and the reverse rotation cooling board within a suitable range, the metal melt droplets colliding with the inclined inner wall surface of the cooling board,
By extending and extending the wall surface, it is possible to simultaneously increase the cooling area and the flake of the quenched metal. In the present invention, it is necessary to control such a rotation speed in the range of 3000 to 5000 rpm for the injection nozzle and 3000 to 7000 rpm for the cooling plate. The reason for this is that when the number of revolutions of the injection nozzle and cooling plate is 3000 rpm or less, the solidified metal does not become flakes but becomes a ribbon-like continuous body, while
When the injection nozzle exceeds 5000 rpm and the cooling board exceeds 7000 rpm,
This is because the solidified metal is pulverized and does not become flakes.

れないからである。An appropriate number of orifices having an orifice diameter of 1.0 mmφ or more are opened on the peripheral surface of the lower portion of the nozzle. This is because if the diameter is less than 1.0 mmφ, the molten droplets to be ejected become fine and the flake-like quenched metal intended by the present invention cannot be obtained.
