Method for detecting a process variable and arc melting plant describing a melting process of metal in an arc melting plant having at least one electrode

摘要

The invention relates to a process for detecting a state variable describing a state of flux describing a melting process of metal (1) in an arc melting plant (100) having at least one electrode (11 to 13), in which a current (I) flowing in at least one electrode (11 to 13) is compared as a first characteristic with at least one second characteristic. According to the invention, it is provided that the second parameter is a magnetic flux density (B) detected in a wall region (44) of a furnace vessel (10) for receiving the metal (1) by means of at least one sensor (31 to 37).
