METHOD FOR OPERATING A VACUUM MELTING SYSTEM AND VACUUM MELTING SYSTEM OPERATED ACCORDING TO THE METHOD

摘要

Metallurgical treatment of a steel melt is provided in a vacuum melting system in which acoustic signals generated in a pan receiving the steel melt are recorded with at least one structure-borne sound pick-up acoustically coupled directly or indirectly to the pan. The acoustic signals are used to determine a variable characterizing the operating state of the vacuum melting system.
