される。Molten metal 2 prepared in an electric furnace or the like is stored in a container 1 having a stopper (not shown). Container of molten metal 2
After the filling is completed, the stopper is opened and the molten metal 2 is injected from the injection nozzle 3 into the atomizing device as an injection stream 21. A spray medium is injected from the atomizing nozzle 4 of the atomizing device to form a spray medium surface 41,
The injection stream 2I from the pouring nozzle 3 falls onto the spray medium surface 41, becomes powder, and is stored in the atomization tank 5 together with the spray medium.

このように従来の装置においては、容器１に溶融金属２
を収容後にストッパを開いて注湯を行っている。連続的

ながら、同時に溶融金属２を注入することはできない。(Problems to be Solved by the Invention) In this way, in the conventional apparatus, the molten metal 2 is placed in the container 1.
After filling the tank, the stopper is opened and pouring is performed. It is not possible to simultaneously or inject molten metal 2 while accommodating the molten metal 2 that is continuously or intermittently supplied in the container 1 .
これは次の理由による。This is due to the following reason.
従来の容器１は、−室構造である。このため、溶融金属
２の供給を受けなから注湯ノズル３から注入を行うと、
容器ｌ内の溶融金属２の乱流のため注入流２１が乱れて

けとは、注入流２１が分裂して多数の粒の形で落下する
現象である。またねじれとは、注入流２１がやや偏平に
なって螺旋状に旋回しながら落下する現象である。The conventional container 1 has a -chamber structure. Therefore, if the molten metal 2 is poured from the pouring nozzle 3 without being supplied,
The injection flow 21 is disturbed due to the turbulence of the molten metal 2 in the container l. That is, the turbulence inside the container 1 caused by the molten metal 2 poured into the container 1 extends to the vicinity of the pouring nozzle 3, causing disturbances such as swinging, scattering, and twisting in the injection flow 21. The fluctuation of the injection flow 21 means that the injection flow 21 is
This is a phenomenon in which the injected flow 21 is deviated from vertically downward to one side and falls, and the scattering is a phenomenon in which the injected flow 21 is split and falls in the form of many particles. Further, twisting is a phenomenon in which the injection flow 21 becomes slightly flattened and falls while swirling in a spiral shape.
噴霧媒面４１へ落下する溶融金属２の注入流２１に乱れ
（振れ、ばらけ、ねじれ等）が発生すると、注入された

凝固し、該ノズル内の空間を閉塞してしまう。すなわち
アトマイズノズル４のブロッキングが発生する。ブロッ
キングが発生すれば、アトマイズの中断は避けられない
。When turbulence (shaking, unraveling, twisting, etc.) occurs in the injection stream 21 of the molten metal 2 falling onto the spray medium surface 41, the injected injection stream 21 is not atomized and solidifies in the atomizing nozzle 4. It blocks the space. That is, blocking of the atomizing nozzle 4 occurs. If blocking occurs, interruption of atomization is inevitable.
したがって従来の注入容器ｌでは、溶融金属２の供給を
受けながら同時に注湯を行へばブロッキングの発生は避
けられない。よって、このような同時注湯は不可能であ
った。Therefore, in the conventional pouring container 1, if the molten metal 2 is supplied and poured at the same time, blocking will inevitably occur. Therefore, such simultaneous pouring was impossible.

とは非能率的である。よって連続的または間欠的に容器
１に溶融金属２の供給を受けながら、同時にアトマイズ
装置への注湯をおこなう必要がある。The amount of molten metal 2 processed at one time as in the conventional method is reduced to 1 at most.
If the amount is small, such as 0.00 kg to several tons, there is no major problem even if the process of supplying the molten metal 2 to the container 1 and the process of atomizing are performed separately. However, when the scale of production is expanded and a large amount of molten metal 2 weighing several tons is to be processed at one time, it is inefficient to carry out both processes separately. Therefore, it is necessary to continuously or intermittently receive the molten metal 2 into the container 1 and simultaneously pour the metal into the atomizer.
従って、本発明の目的は、溶融金属２の供給を受けなが
ら同時に注湯をおこなっても注入流２１に乱れを生じな
い注入方法および装置を提供することである。Accordingly, an object of the present invention is to provide a pouring method and apparatus that does not cause disturbance to the pouring flow 21 even when the molten metal 2 is supplied and simultaneously poured.

This jet of molten metal collides with a wall provided in the second chamber facing in this direction and is reversed. As a result, the decelerated and rectified flow of molten metal is guided to the third chamber through the gap that forms a flow path between the second and third chambers. If the artificial wall surface of the gap forming the flow path from the second chamber to the third chamber is formed into a dogleg shape, the flow of the molten metal can be further calmed by the swirling current generated thereby.

安定した噴流を得ることができる。The molten metal that has passed through the immersion hole 6 becomes a jet and flows into the second chamber 1.
Flows into 2. As a result, the flow in the first chamber 11 that has a high flow velocity, is highly turbulent, and has large temporal changes becomes a stable jet with a high flow velocity but a constant direction. Immersion hole 6
Instead, a narrow vertical gap may be provided in the wall between the first chamber 11 and the second chamber 12, but a more stable jet flow can be obtained by using the seven dipping holes 6.

流が発生する（第１図参照）。The flow path connecting the second chamber 12 and the third chamber 13 is formed by a gap provided in the wall end 7 of the wall 12c that separates the second chamber 12 and the third chamber 13. This wall end 7 is bent into a dogleg shape, and the cross section of the side wall at the entrance of the flow path from the second chamber 12 to the third chamber 13 has this shape. As a result, a vortex is generated at the inlet of the flow path (see FIG. 1).
この渦流の発生は、第２室１２から第３室１３への溶融
金属の流れをさらに沈静化する効果がある。The generation of this vortex has the effect of further calming the flow of molten metal from the second chamber 12 to the third chamber 13.

った。In order to confirm the effects of the present invention, a water model experiment was conducted using a half-sized model of the apparatus shown in FIGS. 1 and 2. The stopper 8 is lowered and water is poured from the ladle 10, and when the water level reaches a predetermined level, the stopper 8 is raised and the pouring nozzle 3 is opened to start pouring. After that, water continued to be supplied from the ladle 10, but the turbulence of the water flow in the first chamber 11 did not affect the third chamber 13, and the water was swayed by the injection flow 21 from the pouring nozzle 3, dispersing, No disturbances such as twisting occurred.
