Consarc electrode eschange ESR furnaces utilize multiple electrodes, one at a time in series, to form a single larger ingot. Electrode exchange furnaces always utilize two ESR furnace heads, and can be designed to exchange into either a static melt station or a withdrawal melt station that is located between the two heads.
Frequently these furnaces will have one or two “side” melting stations as well, which can allow for higher productivity when melting more standard product in a single electrode to single ingot configuration.
