Abstract

A cooled converter trunnion ring, which is arranged at a distance from the converter, encompasses the converter and is connected to a coolant supply station. In order to achieve good accessibility of the trunnion ring by simple measures and to ensure reliable cooling of the loaded trunnion ring areas with low energy expenditure, a pipe coil, which runs in a largely meandering fashion and through which a liquid coolant flows, is provided on the inner surface of the inner side member substantially facing the converter of the steel mantle of the converter trunnion ring.
