Abstract of the Disclosure A cover for a metallurgical vessel comprises an annular outer tubular collar defining a center, a plurality of tubular legs extending inwardly from the collar toward the center, and an annular inner tubular collar fixed to the legs and defining a plurality of throughgoing passages. The inner collar is formed by respective inwardly concave tubular sections defining the passages and respective inwardly convex and tubular elbow sections carried on the legs between the passages and forming an undulating annulus with the inwardly concave sections. A multiplicity of cooling tubes extend between the collars and legs and are connected thereto, and a cooler is provided for circulating a coolant through the tubes, collars, and legs. This system ensures excellent cooling right at the passages, so electrodes extending through these passages need not be provided with their own coolers.
