Definitions

  • evaporative cooling is preferably used, which is designed in such a way that there is little or no condensation of the steam in the individual cooling units.
  • Coolant supply is led around the furnace to two collecting lines 14 and 15, to which the cooling units 5 / 1.5 / 2 ... 5 / n between the box girders 3 / 1.3 / 2 ... 3 / n are connected independently of one another by means of supply lines 16 and derivatives 17 are connected via shut-off devices 18.
  • the lines 17 are connected to the thick-walled tubes 10 of the edge sections 6/1, 6/2 ... 6 / n. The area of the container wall 5 directly adjacent to the furnace cover 7 is thus sufficiently cooled.
  • the lines 16 and 17 are separated from the cooling unit and the screw connections 8 between the edge section 6/1 and the box girders 3/1 and 3 / n are loosened.
  • the brittle layer of slag and the spray compound burst off in the area of the joints as a result of a brief, jerky pull-up using a crane and lifting tongs, and the cooling unit can be lifted upwards.
