Cooled converter carrier ring

摘要

The cooled converter carrier ring (20) is positioned with a gap around the converter (10), and is connected to a cooling agent supply station. It is characterised by the fact that the inner surface (22) of at least the wall (24)- which faces the converter - of the steel carrier ring shell (21) is provided with a meandering pipe system (31) for circulation of a liq. cooling agent. At the same time, a part of the pipe profile is formed by the inner surface (22) of the carrier ring shell (21), while the distance (a) between the middle axes of the adjacent pipes equals at least twice the pipe dia. (D).
