Abstract (en)

The invention relates to a ring furnace having a plurality of hollow partitions (3, 3') acting as flue walls and defining baking pits for stacking carbonaceous articles therein. So as to allow thermal expansion of the bricks (110) during use, while preserving the transverse imperviousness of the hollow partitions, at least one built-in expansion joint is arranged in at least one of said hollow partitions by providing at least one gap (111, 112) between specified bricks in each said lateral wall and by arranging sealing bricks (1111, 1112, 1121, 1122) within said hollow partition so as to overlap said gap and thereby seal the same.
