Definitions

  • the present invention relates to a device for cooling tanks brought to high temperatures, for example ladles for steelworks.
  • the invention aims to provide an apparatus for cooling ladles of steelworks, and generally tanks brought to high temperature, in a relatively short time. It also offers a cooling device of simple construction and minimum size.
  • an apparatus comprising a ferrule open at its lower and upper ends, a fan housed inside the ferrule, and a frustoconical wall fixed to the ferrule near the lower end of this and surrounding the shell away from it as one moves away from said lower end.
  • Supports are provided, which are intended to rest on the upper edge of a tank to be cooled and to support the frustoconical wall in such a way that, the shell extending inside the tank to be cooled, a peripheral space is formed between the upper edge of the tank and the upper end of the frustoconical wall.
  • the apparatus according to the invention makes it possible to cool steel ladles in just a few hours, where it was usually several days to cool them. It therefore results from the use of the device according to the invention, a significant saving in investment and storage costs.
  • the device comprises a metal ferrule 1 open at its ends and in which is housed a fan 2.
  • a metal wall 3 On the ferrule 1 is fixed a metal wall 3 forming the lateral surface of a truncated cone and which surrounds the ferrule, said metal wall 3 moving away from the ferrule as the section of the truncated cone moves away from the lower end of the ferrule.
  • the frustoconical wall 3 is advantageously made of refractory steel. Its upper end is fixed under a cover plate 4 traversed by the upper end of the ferrule 1.
  • On the periphery of the frustoconical wall 3 are fixed supports 5 intended to rest on the upper edge of a tank to be cooled (shown partially at 10 in FIG.
  • the upper end of the shell 1 carries a silencer 8 or a mesh suction cone 9.
  • a suspension device 11 for suspending the device from a lifting machine.
  • the suspension device 11 is preferably oriented perpendicularly to one of the supports 5 so as to allow easy installation of the device on a beaker ladle, the latter then coming to be automatically placed in the angle between two consecutive supports.
  • the fan 2 When the fan 2 is started, it draws fresh air inside the shell 1 and launches a flow of pulsed air towards the bottom of the tank. This air flow flows along the side wall of the tank going up towards the frustoconical wall 3 which then directs it outwards.
  • the tank can thus be effectively cooled in a very short time. It has been found that a casting ladle of 280 tonnes for example, brought to about 800 ° C is cooled to a temperature of about 20 ° C, in a period of just nine hours while it such ladles should usually be left to stand for about nine to ten days before they are cooled and their refractory linings can be repaired. It therefore results from the use of the cooling device according to the invention a significant reduction in the cost of investment in equipment and the cost of storage.
  • the fan 2 is mounted inside a second ferrule 12 which is housed in the ferrule 1 by simple sliding. This allows the fan 2 to be easily removed from its shell 12 for maintenance or repair.
