PURPOSE: To eliminate or reduce the space for separating storage of the power source panel to store the component for power source and to make the maintenance easy with approaching the power source parts and magnetic conduit by storing all or one part of the power source parts of electromagnetic conduit on the lower part zone of the magnetic conduit.

CONSTITUTION: A fire resistant container 1 stores a molten metal in the inner part and electromagnetic conduit 2 is set up with passing the one end through the side part of the container 1 and with inclining the downstream toward the upper part. An electromagnetic conduction device is provided on the bottom part of the magnetic conduit 42 as well, the molten metal is transferred to the slant upper part, moved to a guide conduit 5 and to a separate container. A plate 6 is connected to the rack 3 of the conduit 2 and provided on the lower part zone 7 of the conduit 2. The power source parts 8 of transformer and capacitor for improving power factor, etc. are respectively fixed onto the plate 6. The plate 6 is not always necessary to be provided and the power source parts 8 may be fixed on the floor face 4 of the lower part zone 7 of the conduit 2. All of the power source parts may not always by stored in the lower part zone 7 thereof and one part of the power source parts may be stored.
