A binding system for applying a vertical compressive force to the refractory walls of a rectangular or circular furnace comprises a compressive member engaging a laterally extending surface of the furnace wall and a support member to which the compressive member is connected. The compressive member preferably comprises a coil spring which acts directly on the laterally extending surface or indirectly through a force-applying member. The force applied by the compressive member is sufficient to control vertical expansion and substantially prevent vertical expansion of the furnace walls due to infiltration of material into the joints between the refractory bricks during operation of the furnace.
L'invention concerne un système de fixation destiné à appliquer une force compressive sur les parois réfractaires d'un four rectangulaire ou circulaire, qui comprend un élément de compression en prise avec une surface de la paroi du four s'étendant latéralement et un élément de soutien auquel ledit élément de compression est relié. De préférence, l'élément de compression comprend un ressort à boudin qui agit directement sur ladite surface s'étendant latéralement ou indirectement par le biais d'un élément d'application de force. La force appliquée par l'élément de compression est suffisante pour réguler l'extension verticale et empêcher sensiblement celle des parois du four due à l'infiltration de matière dans les joints entre les briques réfractaires lors du fonctionnement du four.
