面レベル炉１が受湯側５に対し遠近方向に、すなわち図
中左右方向に移動できるようになっている。FIG. 1 shows an example of a device for supplying a molten metal according to the present invention. In the drawing, reference numeral 1 denotes a constant level furnace in which the level 2a of the molten metal 2 is always kept constant. The lower end is provided with a gear 4 that rolls freely on a plane 3 so that the constant level furnace 1 can move in a distance direction from the hot water receiving side 5, that is, in the horizontal direction in the figure. .

湯管10を直線状にすることできない。As shown in FIG. 1, an electromagnetic pump 13 composed of an iron core 11 disposed at the axial center and a coil 12 disposed at the outer peripheral portion is attached to the intermediate hot water distribution pipe 7. The electromagnetic pump 13 induces an induced current in the metal melt 2 in the intermediate hot water distribution pipe 7, is driven by an electromagnetic force generated by the induced current and a magnetic field generated by the coil 12, and transfers the molten metal 2 to the receiving side 5. In the case where the electromagnetic pump 13 is mounted in the middle of the hot water distribution pipe 10, the iron core 11 needs to be fixed, so that the hot water distribution pipe 10 cannot usually be made straight.
そこで本実施例では、第１図に示すように鉄心ホルダ

16を構成している。As shown in FIG. 1, an orifice 14 is provided inside the distal end hot water distribution pipe 9, and constitutes a narrowed portion having a smaller cross-sectional area than the inside of the distal end hot water distribution pipe 9. At the end of the hot water distribution pipe 9, an adapter 15 is provided which is raised up to a position higher than the molten metal surface 2a and whose tip is bent downward in an inverted U-shape as shown in FIG. Hot water pipe system with hot water pipe 10

ようになっている。Inside the adapter 15, as shown in FIG.
A molten metal surface 17 having the same height as 2a is formed so that the molten metal surface level can be maintained. And with this adapter 15,
The metal pipe 2 can always be filled with the molten metal 2 in the hot water pipe 10.

溶湯22が残るのを防止できるように考慮されている。As shown in FIGS. 2 and 3, the orifices 14 are formed by providing U-shaped notches 14b at two upper and lower portions of a disk 14a having the same outer diameter as the inner diameter of the tip water pipe 9 respectively. ing. And, by providing notches 14b in the upper and lower two places, it is possible to prevent air from being confined in the hot water distribution pipe system 16, and when the inside of the hot water distribution pipe system 16 is emptied, Consideration is given so that the molten metal 22 can be prevented from remaining.
次に、本実施例の作用について説明する。 Next, the operation of the present embodiment will be described.
