First, the control circuit 9 is operated by the drive device 5 to move the stopper 4 while the inductor 6c of the electromagnetic pump is generating a strong moving magnetic field toward the molten metal holding furnace 1 side.
is raised to release the fitted state between the tip of the stopper 4 and the molten metal inlet 3b1 of the hole 3b. Next, by operating the control circuit 9 to weaken the power to the inductor 6c of the electromagnetic pump 6, the molten metal 2 existing in the small chamber 3 is transferred to the hole 3b formed in the molten metal holding furnace 1 and the molten metal introduction hole 6a of the electromagnetic pump 6. The hot water flows into the hot water storage tank 7 through the outlet 6d. In this process, the amount of molten metal flowing out per unit time from the outlet 7a of the hot water storage tank 7 is
If the amount of molten metal introduced into the hot water storage tank 7 per unit time is large, the level of molten metal in the hot water storage tank will rise.
Therefore, the molten metal level in the hot water storage tank 7 gradually decreases due to the action of the control circuit 9 which reaches a constant molten metal level by the level sensor 8, but increases again by weakening the check force again. Based on such an operation, the level of molten metal in the hot water storage tank 7 is kept almost constant, and the amount of molten metal flowing out from the molten metal supply port 7a per unit time can be made constant.
