Abstract
To permit placement of a stopper element, preferably including a cylindrical alignment plug (13) accurately with respect to an outflow pipe (3, 3', 3') of a metallurgical vessel adapted to contain a melt, an operating rod (5) vertically projecting from the stopper (6) is surrounded by a refractory sleeve (10), and secured to a support arm (23), which support arm is vertically movable and capable of transmitting rotation to the operating rod, the operating rod is connected to the support arm by a coupling link (48) which extends radially from the operating rod and is clamped by a clamping connection (46) to the support arm. The clamping connection (46) permits longitudinal adjustment of the upper end portion of the operating rod (5) as well as angular adjustment with respect to the support arm. Preferably, a part-spherical joint (50) couples the upper end portion of the operating arm (5) to the coupling link, and a part-spherical lower joint (11, 1311) with spherical surfaces formed on different materials connect the plug and/or adjacent portion of the sleeve (10) to the operating rod.
