摘要： Gas purging system comprising a gas purging plug (10) and gas purging plug (10) for metallurgic applications and a gas supply pipe (30) connected to the gas purging plug (10), the gas purging plug (10) with a ceramic refractory body (10k) with a first end (10u) and a second end (100); the second end (100) is in the mounted position of the gas purging plug (10) in contact with a metal melt (41); the first end (10u) is at least partially covered with a metal cover (12.1), the metal cover (12.1) comprises an opening (16) to which optionally a gas supply adapter (20) is connected; the gas purging plug (10) is designed in such a way, that a purging gas which is supplied via the gas supply pipe (30) to the opening (16) flows through the body (10k) and exits the body (10k) at the second end (100); and wherein at least one electronic sensor (70, 70.1, 70.2, 70.3, 70.4) is in contact with the gas purging plug (10), to detect an oscillation waveform of a mechanical vibration (81). The gas purging system further comprises a data processing unit (80) for acquiring the oscillation waveform of a mechanical vibration (81) detected by the electronic sensor (70, 70.1, 70.2, 70.3, 70.4) of the gas purging plug (10) and for calculating a bubble index-signal (83) from the oscillation waveform of a mechanical vibration (81) detected; a control unit (100); wherein the control unit (100) is configured to: displaying the bubble index-signal (83) and/or varying the volume flow (102) through the gas supply pipe (30) depending on the bubble index signal (83) and/or -generating a warning signal (101) when the bubble index signal (83) lies outside a defined range.
