| 摘要 |
The invention relates to a closure and control device for the pouring of liquid metal melt contained in a metallurgical vessel having at least one elongate outlet, in particular when pouring for continuous casting close to the final dimensions, as in continuous strip casting or in casting thin slabs. This closure and control device is characterised by a refractory stator with a rotor placed therein associated with the outlet. The stator and the rotor abut one another with circular cylindrical working surfaces and (for the passage of melt) are provided with cooperating openings extending in the axial direction substantially over the entire length of the stator and rotor, the rotor being rotatable and/or axially displaceable with respect to the stator.
