Abstract

A tap hole construction of a metallurgical vessel with a refractory lining has a plurality of annular bricks (4) arranged in the longitudinal direction of the tap hole and having central openings which provide the tap hole flow passage (1) and refractory casting or spraying material (6) around said bricks (4) to fix them in place. To improve the centering of the tap hole and to make its renewal easier, at least one of the annular bricks (4) has at least one projection (7) projecting radially from its peripheral outer face. After introduction of the surrounding material (6), the projection becomes embedded in the material (6).
