きる。 In the above configuration, each of the first pipes 4 and 5 has a
When a moving magnetic field is generated in one direction of arrow Y shown in the figure,
Molten metal 2 is pumped up through each of the pipes 4 and 5. In this case, the molten metal 2 can be supplied to two different molds, and the amount of molten metal supplied to each mold can be individually controlled by the current supplied to the coils 8b, 9b. Next, a case will be described in which a moving magnetic field in the direction of arrow Y1 is generated in one of the pipes 4 and 5, and a moving magnetic field in the direction of arrow Y2 (opposite direction to Y1 ) is generated in the other. For example, when a moving magnetic field in the direction of arrow Y1 is generated in the pipe 5, the molten metal 2 is drawn up by the moving magnetic field, and therefore the molten metal 2 can be supplied to one mold.
On the other hand, when a moving magnetic field in the direction of arrow Y2 is generated in the pipe line 4, the molten metal 2 in the heat-insulating container 1 can be stirred by this moving magnetic field. That is, the moving magnetic field within the pipe 4 is strongest at the center of the cross section, and weaker at the peripheral edge (inner wall). As a result, the molten metal 2 in the center of the pipe line 4 is successively returned to the heat-insulating container 1 due to the moving magnetic field in the direction of arrow Y2, while the molten metal 2 in the heat-insulating container 1 moves along the inner wall of the pipe line 4. and enters into the pipe line 4. This operation utilizes the so-called side-end effect of a linear motor, and the molten metal 2 in the heat-insulating container 1 is stirred based on the molten metal flow obtained thereby.
Thereby, the temperature of the molten metal 2 can be made uniform.

2 and 13 may be joined together. Also,
The pipes 4 and 5 may have different cross-sectional areas. In this case, the flow rate of the molten metal 2 can be changed for each pipe.
