Abstract
The present invention pertains to a device for installing and removing gas purging plugs (17) for metallurgical vessels, comprising a guide (7) for axially displacing the gas purging plug (17). On the one hand, movement exactly in the axial direction can be achieved during introduction, and, on the other hand, the extracted gas purging plug can be brought into an ejection position by providing hinges (6, 11), which permit at least two independent pivoting movements of the gas purging plug (17) around different axes (6a, 11a).
