IMPIANTO MAGNETODINAMICO, IN PARTICOLARE PER LA FUSIONE E LA COLATA DI METALLI IN FORME DA FONDERIA.

摘要

Appts. or plant includes at least one inductor, and at least one electromagnet, which are connected to two autotransformers supplied with mains a.c. A variable capacitor is used to provide symmetrical currents, esp. from a 3-phase a.c. supply. The windings of the transformers are connected to different phases of the a.c. supply; and a tapping on each winding is used to supply electric current to the electromagnet via a switch. The inductor is connected to one phase of the mains a.c. and also to a tapping on one transformer. The result is that the inductor can be used alone as a furnace or, when both the inductor and the electromagnet are switched on, a pump is formed which can be used for dosing molten metal into foundry moulds.
