Gas purging element (10) comprises (a) a refractory ceramic body having a first end and a second end. The second end is in the installed state of the gas purging element in contact with a molten metal. The first end is externally covered by a metal sheath (12) having an opening (16) which is followed by a gas connection pipe (20). The gas purging element, the body and the gas connection pipe are designed such that a treatment gas flows through the body, which is supplied via the gas connection pipe and emerges from the body at the second end. Gas purging element (10) comprises (a) a refractory ceramic body having a first end and a second end. The second end is in the installed state of the gas purging element in contact with a molten metal. The first end is externally covered by a metal sheath (12) having an opening (16) which is followed by a gas connection pipe (20). The gas purging element, the body and the gas connection pipe are designed such that a treatment gas flows through the body, which is supplied via the gas connection pipe and emerges from the body at the second end. The gas connection pipe is connected to the metal sheath and is formed as a plug or socket of a plug connection for connecting to a corresponding socket, or a corresponding connector of a gas supply line (30). An independent claim is also included for a gas supply line for a gas purging element, comprising a first end and a second end for connection to the gas connection socket of the gas purging element, where the second end corresponds to the gas connection pipe as a plug or socket of the plug-in connection between the gas connection pipe. |
