Various embodiments provide for a gas purging plug () with a ceramic refractory body (k) with a first end (u) and a second end (o); the second end (o) is in the mounted position of the gas purging plug () in contact with a metal melt (); the first end (u) is at least partially covered with a metal cover (), the metal cover () comprises an opening () to which optionally a gas supply adapter () is connected; the gas purging plug () is designed in such a way, that a purging gas which is supplied via the gas supply pipe () to the opening () flows through the body (k) and exits the body (k) at the second end (o); and wherein at least one electronic sensor () is in contact with the gas purging plug (), to detect a mechanical vibration ().

Gas purging plug, gas purging system, method for characterization of a gas purging plug and method for purging a metal melt

With a method for detecting variables in an outlet of a metallurgical vessel, different variables in the outlet are detected or measured by at least one coil surrounding the outlet channel and/or an induction coil of an induction heater as a monitoring system, wherein the variables relate to the slag portion when pouring out the metal melt, wear condition of refractory parts in the outlet channel, the solidified metal melt, flow rate and/or plugging mass in the outlet channel. After evaluation, a closure element for the outlet is actuated, heating of the metal in the outlet channel is activated and/or renewal of the outlet channel is triggered. In this way, optimum operation in the pouring of metal melt out of a vessel is simply achieved, wherein occurrence of irregularities are detected during the entire pouring, and pouring out of slag can be successfully prevented at the end of the pouring.
