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

摘要

In a method for operating a vacuum melting system for the metallurgical treatment of a steel melt and a vacuum melting system operated according to said method, acoustic signals generated in a pan (6) receiving the steel melt are recorded with at least one structure-borne sound pick-up (30-1, 30-2, 30-3, 30-4) acoustically coupled directly or indirectly to said pan (6) and are used for determining a variable characterising the operating state of the vacuum melting system.
