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.
Claims5
An improved arrangement for securing plate-type coolers on an inside furnace shell of a metallurgical furnace, such as a blast furnace, the coolers being of the type having coolant conducting pipes extending through openings in the furnace shell, protective tubes being surrounded in spaced relationship about the pipes and extended into the cooler, and means for sealing the openings in the furnace shell to prevent gas escape, the improvement comprising at least one of the protective tubes spaced about a first coolant conducting pipe extending in a respective horizontal plane of the plate cooler being mounted to the shell as a fixed support, and the other protective tubes in the same plane being mounted to the shell as horizontally displaceable supports, and at least one protective tube extending in a second horizontal plane spaced about said first coolant conducting pipe opposite to the fixed support being mounted to the furnace shell as a vertically displaceable support, and the other protective tubes extending in the second plane being mounted to the shell as movable supports.
