However, it has been proven in practice that due to the possibility of miscalculation and improper control, cracks can occur where the metallurgical steel flows in an uncontrolled manner through the deck and damages the deck or even destroys it completely.

Embodiment Construction
[0015] Figure 1 shows a schematic view of a slide cover 10 fastened to a metallurgical vessel 15, only partially shown, comprising, for example, a tank containing metallurgical steel in an extrusion plant. The components of the vessel 15 are shown as a steel jacket 11 , a refractory covering 12 , a perforated stone 14 and a refractory sleeve 13 with an outlet 16 .
[0016] The sliding cover 10 comprises an upper housing part 17 in which a refractory cover 21 is fastened. A slidable cover part 22 is accommodated in the other housing part 19 , wherein the housing part 19 is held in the housing structure 18 and can be moved by a drive element 25 into an open position - as shown - or into a closed position. This drive element 25 takes the form of a hydraulic piston / cylinder element and is thus activated by a hydraulic combination 29 through the pipes 26 , 27 . Furthermore the cover plates 21 , 22 are pressed against each other by spring elements 23 so that a sufficient seal is pr...

The invention relates to a method for operating a sliding gate for metallurgical vessels in which the sliding gate (10) has at least two fire-resistant gate plates (21, 22), which can be tensioned against one another and which are each arranged inside a respective housing part (17, 19) in a manner that enables them to slide relative to one another. Spring elements (23) are provided in at least one of the housing parts (17, 19) in order to tension the gate plates (21, 22). One gate plate (22) can, with its housing part (19), be slid into a closed or open position by means of a drive element. An offline and / or online diagnosis of the operating state is carried out, in particular, in the area of the gate plates (21, 22, 41, 42) during which one or more variables with regard to dimensions, temperatures, pressures and / or forces are measured at the sliding gate (10, 40) and are evaluated directly or while including additional relevant process parameters in order to be able to locate it during the operating state and, therefore, during an additional use of the sliding gate (10). Interruptions can be largely prevented as a result.
Description
technical field [0001] The invention relates to a method for operating a sliding cover of a metallurgical container, wherein the sliding cover at least includes a plurality of refractory cover plates that can be tensioned in reverse, and each cover plate can slide in reverse, and along the Placed against the sliding surface, and a spring element is designed therein to tension the cover in at least one housing part, and one of the cover plates together with the housing part can be pushed into the closed or open position by the drive element. Background technique [0002] Sliding lids are especially suitable for extrusion plant tanks or dispensing containers to control the pouring of molten steel. The refractory decks and refractory sleeves used for these slides, as well as the mechanisms supporting them, are subject to severe wear and tear through which the liquid metallurgical steel flows. These covers and sleeves must therefore be replaced frequently. [0003] For high ef...
