Abstract

L'invention concerne une fermeture coulissante pour récipient métallurgique, qui comprend une plaque coulissante (2) réfractaire, allongée, remplaçable et disposée dans un cadre métallique (1), dont le sens de la longueur (L) correspond au sens de coulissement de la fermeture coulissante. La fermeture comprend en outre des moyens (3) de serrage de la plaque coulissante (2) dans le cadre métallique (1), qui comprennent un patin en biseau (10) sollicité par un ressort (9) et ajustable transversalement par rapport au sens de coulissement de la fermeture coulissante. Ce patin en biseau (10) peut coopérer avec une pièce complémentaire (11) qui peut être reliée à la plaque coulissante (2) et qui agit sur la plaque coulissante (2) dans le sens de sa longueur (L). Les déplacements d'oscillation de la plaque coulissante mobile qui surviennent en fonctionnement sont repris et le dispositif de serrage garantit à tout moment un serrage fiable de cette plaque coulissante.
