Abstract (en)
[origin: EP0361052A2] The refractory stator/rotor unit for a nozzle gate of a vessel (11) containing molten metal consists of a stator (15) fastened in the vessel wall (14), and of a rotor (16), which is rotatable in the latter from the underside (11') of the base of the vessel and serves for opening or closing the gate. The unit projecting into the vessel has transverse openings (17, 18) extending therein and, starting from these openings (17, 18), a nozzle opening (19) leading out of the vessel. In the entire region lying within the vessel, a sealing cylindrical surface (20), surrounding the transverse openings (17, 18) is provided between the rotor (16) and the rotator (15) while in the region lying in the vessel wall (14) a clearance (22), compensating for the different thermal expansions of stator and rotor, is provided in order to prevent the unit from seizing. A gate system is thus provided which is very simple and space-saving and functions with high operational reliability. <IMAGE>
