Abstract: The withdrawing device comprises a bearing device for bearing the withdrawing device on the metallurgical vessels, and a drawing device for coupling and drawing gas sink from the external side of the metallurgical vessels. The bearing device comprises an attaching device (4) for attaching on and/or mounting on a ribbing, strutting or stretching the metallurgical vessels in an attaching position. The bearing device has a flat base (5) with a bearing area, which is stretched for bearing the withdrawing device on external side of the ribbing, strutting or stretching of the metallurgical vessels. The withdrawing device comprises a bearing device for bearing the withdrawing device on the metallurgical vessels, and a drawing device for coupling and drawing gas sink from the external side of the metallurgical vessels. The bearing device comprises an attaching device (4) for attaching on and/or mounting on a ribbing, strutting or stretching the metallurgical vessels in an attaching position. The bearing device has a flat base (5) with a bearing area, which is stretched for bearing the withdrawing device on external side of the ribbing, strutting or stretching of the metallurgical vessels. The base is formed as flat frame and/or plate with the bearing surface. The attaching device comprises positioning elements for cooperating with power- and/or form-fitting positioning of the drawing device in the attaching position on the ribbing, strutting or stretching of the metallurgical vessels. A projection is formed as positioning projection (8) that extends itself in the attaching position of the drawing device with a head stretching component in the direction of the base for metallurgical vessel. The drawing device is fixed over the positioning projection at the later ribbing, strutting or stretching of the metallurgical vessels in the attaching position. The positioning projection is formed with projections (10) formed as backup projection in claw or hook manner and/or a curvature. The withdrawing device is arranged parallel to contact surface (6) in attaching position of the metallurgical vessels. A slit guidance is equipped for the withdrawing device in which the withdrawing device is changeably arranged parallel to contact area. The withdrawing device is arranged along the ribbing, strutting or stretching along parallel to contact area or base in guide- or roll relocatable manner. The attaching device comprises a first roller pair that adjoins in attaching position at the rib, the strutting or the stretching at the inner side. The rib is equipped to the projection over an equipped area for attaching and/or displacing the withdrawing device. The projection extends itself in an assembly area of the metallurgical vessel for attaching the withdrawing device at the interior and end side of the rib with a stretching component. The base comprises a recess on its contact area. In the recess, the projection formed as a fixing projection for fixing the withdrawing device provided on the ribbing, strutting or stretching interferes in a certain attaching position. A revolvable base for supporting the withdrawing device in its attaching position is arranged at the metallurgical vessel on the contact area. The drawing device is arranged to the base so that the gas sink is connectable in the attaching position of the withdrawing device in a coupling direction vertical to the contact area and extendible in a withdrawing direction vertical to the contact surface. The withdrawing device comprises a vertical turning spindle variably positioned to the contact area and guided in the base. The turning spindle comprises an actuating end modified in the attaching position of the withdrawing device, and a coupling end with a coupling mechanism for coupling on the gas sink in the attaching position of the drawing device.
