ABSTRACT:
In supplying molten metal to a mold by means of an electromagnetic pump mounted on a metal container, the molten metal received in the pump is held in high temperature by means of partition walls longitudinally extending in the pump, even when the supply of molten metal is suspended for a long period. The partition walls define several passageways. In this period of suspension the driving force of travelling magnetic field is directed to the molten metal container and causes circulation of molten metal through central passageway and side passageways. Through this circulation molten metal in the pump is substantially replaced by molten metal in the container, thus making it possible to prevent solidification of molten metal in the pump by maintaining high temperature therein.
