Abstract
A sliding closure unit includes a stationary refractory plate to be mounted on a metallurgical vessel, a movable refractory plate, a slide frame supporting the movable refractory plate and movable in a direction of movement between an open position with discharge openings in the movable and stationary refractory plates in alignment and a closed position with the discharge openings out of alignment, and tensioning devices on opposite sides of the movable refractory plates for pressing the movable refractory plate against the stationary refractory plate. The force of the tensioning structures is distributed evenly along the opposite sides of the movable refractory plate by strip members mounted in the slide frame for movement relative in the direction of the thickness thereof. A respective strip member is positioned on each opposite side of the movable refractory plate and is positioned between the tensioning structure on such side and the bottom surface of the movable refractory plate on such side.
