GAS PURGING ELEMENT AND CORRESPONDING GAS SUPPLY LINE

A gas purging device for metallurgical applications comprising a gas supply pipe and a gas purging element that features a ceramic fireproof body with a first end and a second end in a mounted position of the gas purging element in contact with a metal melt. The first end is covered by a metal coat which features an opening to which a gas supply adapter connects. The gas purging element, the body and the gas connection adapter are designed such that a treatment gas supplied via the gas supply adapter flows through the body and exits the body at the second end. The gas supply adapter is connected to the metal coat and at its free end is designed as a plug or socket of a push-fit connection for connection to a corresponding socket or plug of the gas supply pipe. A secure element with an inner screw thread mechanically secures the push-fit connection according to a cap nut together with a corresponding outer screw thread at the free end of the gas supply adapter. La présente invention concerne un élément de barbotage sur un récipient métallurgique, ainsi qu'une conduite d'alimentation en gaz correspondante.
