Abstract

Event pour four à anodes Évent pour un ouvreau d’un four à cuisson d’anodes, ayant : un châssis; au moins un volet déplaçable par rapport au châssis d’une position fermée dans laquelle la communication entre l’environnement et la cloison creuse est limitée à une position ouverte dans laquelle l’évent permet la communication entre la cloison creuse et l’environnement; et un mécanisme de sollicitation engagé à l’au moins un volet et exerçant une force de sollicitation sollicitant l’au moins un volet dans la position ouverte, la force de sollicitation étant inférieure à une force de pression résultante d’une différence entre une pression nominale de la cloison creuse et une pression de l’environnement, la force de sollicitation étant telle que l’au moins un volet se déplace de la position fermée vers la position ouverte par l’intermédiaire de la force de sollicitation lorsque la force de pression diminue sous un seuil déterminé.
