Abstract

Slide closure for a vessel that operatively contains molten metal, comprising: a slide housing including a recess receiving a first refractory closure plate; a slide unit including an opening receiving a second refractory closure plate; wherein at least one clamping mechanism is arranged to start the clamping of the corresponding refractory closure plate via an actuation of the at least one clamping mechanism when the slide unit is displaced relative to the slide housing and the first and the second refractory closure plates are distant apart from each other, essentially before the first and the second faces of the respective first and the second refractory closure plates are in contact under pressure.
