Abstract
La présente invention concerne un procédé et un dispositif de fabrication d'une structure thermiquement stable pouvant faire partie de fours. Plus particulièrement, cette invention concerne des structures de base destinées à des fours tubulaires utilisés pour calciner des blocs d'anode qui s'utilisent dans l'électrolyse de l'aluminium. La structure de base repose sur un socle constitué d'un certain nombre de colonnes (15, 16, 17, 18, 19, 20) et est constituée par une première couche B' de briques réfractaires reposant sur le socle. Ces comportent des éléments de blocage (25, 26) à leur partie supérieure, sur lesquels on dispose une deuxième couche C' de briques réfractaires dont le dessous comporte des éléments de blocage équivalents complémentaires. Ainsi, les deux couches sont reliées l'une à l'autre et l'on obtient une structure à la stabilité éprouvée par rapport aux charges thermiques et mécaniques.
