METHOD FOR SERVICING A SLIDE CLOSURE AT THE SPOUT OF A METALLURGICAL VESSEL, AND A SLIDE CLOSURE

Method for servicing or maintenance of a sliding closure on an outlet of a metallurgical vessel includes controlling, using a robot for automated maintenance, a drive on the sliding closure to selectively enable release of the sliding closure or drive, and enable unfolding of the sliding closure. When the sliding closure is unfolded, a first refractory closure plate is, together with a first cassette, insertable into or removable from a housing of the sliding closure and a second refractory closure plate is, together with a second cassette, insertable into or removable from a slider unit coupled to the housing. In an available manual maintenance stage at the same location, the cassettes are fixed in the housing and slider unit and the closure plates are insertable manually directly into the respective cassette to be centered and fastened therein, or the closure plates are releasable from the respective cassette.
