ABSTRACT CLOSURE AND/OR CONTROL ELEMENT FOR A METALLURGICAL VESSEL A closure and/or control element of a metallurgical vessel (2) has a fixed, vertical inner tube (3) with a lateral opening (9) and an outer tube (6) which is movable with respect to it and with a lateral opening (12). In order to control the discharge height and thus the discharge velocity, the extent of the opening (9) is larger than that of the opening (12). At the upper end of the working stroke (A) the opening (9) is closed in its lower zone. At the lower end of the working stroke (A) the opening (9) is closed in its upper zone. (Figure 1)
