Induction melting furnace

Plant for inductive melting of metals. Eddy currents are induced in an alternating electromagnetic field in the metal insert to be melted, which then heats it up due to its electrical resistance and causes it to melt. The induction crucible furnace, operated at mains or medium frequency, is the most frequently used today.

Fig. 1 shows the principle of inductive melting schematically.
