A thermally compensated structural element (1) comprising an upper element (2) and a lower element (3). The upper element consists of an angle section with a mainly horizontal part (15) and a mainly vertical part (16). The lower element (3) is designed with a base part (17) and a vertical part (18). The upper element (2) and the lower element (3) are both connected to connection elements (5, 6, 7, 8, 9) in such a way that thermally induced expansion/contraction is compensated for. The solution comprises further features which will contribute to preventing distortion of the structural element. Structural elements of the above type may be used in a base frame for covers which are used in thermal processes such as section covers for use in furnaces for calcining of carbon bodies.
L'invention concerne un élément structurel thermiquement compensé (1) comprenant un élément supérieur (2) et un élément inférieur (3). L'élément supérieur consiste en une section d'angle dotée d'une partie sensiblement horizontale (15) et une partie sensiblement verticale (16). L'élément inférieur (3) est conçu avec une partie de base (17) et une partie verticale (18). L'élément supérieur (2) et l'élément inférieur (3) sont tous deux connectés à des éléments de connexion (6, 7, 8, 9) de manière à compenser l'expansion/contraction induite thermiquement. La solution comprend, en outre, des caractéristiques qui contribuent à prévenir la distorsion de l'élément structurel. Les éléments structurels du type susmentionné peuvent être utilisés dans un cadre de base pour des couvercles qui sont utilisés dans des traitements thermiques tels que des couvercles de section s'utilisant dans des fours destinés à calciner des corps en carbone.
