Abstract

An improved arrangement for securing a plate-type cooler in metallurgical furnaces is disclosed. The cooler comprises a cast body including embedded cooling pipes provided with protective tubes which are run into the cooler body and secured to the outlets of the cooling pipes. At a first level, at least one of the protective tubes is designed as a fixed support and the other tubes at the same level are designed as horizontally displaceable supports to allow for a thermal expansion. At a vertically opposite level, at least one of the protective tubes is designed as a vertically displaceable support and the other tubes extending at the same level are designed as movable supports.
