Definitions

  • the present invention relates to a slag cleaning device for foundry furnace crucibles comprising a shaft driven in rotation by a motor and carrying at its lower end tools for removing slag from the crucible.
  • the object of the present invention is to provide a slag cleaning device which does not require emptying. This optimizes fusion engagement and increases production.
  • the use of the device leads to a better thermal balance of the refractory and to a gain in rammed earth consumption. Health and safety conditions are improved.
  • the apparatus according to the invention is characterized in that the scouring tools are rigidly connected to the drive shaft so as to allow scouring of the crucible in the liquid metal.
  • the apparatus is mounted on a crucible 1 of a foundry furnace forming a chamber or tank containing the liquid metal 3.
  • the internal wall of the chamber is formed by a lining or a refractory brick.
  • the apparatus marked 2 as a whole set for eliminating the dross depositing on the interior lining of the crucible.
  • the apparatus 1 compotes a frame 21 which is placed on the upper edge of the oven so as to cover the opening of the latter.
  • This chassis supports the moving parts of the device.
  • a carriage 22 carrying a drive motor 23 is suspended from the chassis by a lifting mechanism 24.
  • the carriage 22 is guided vertically in the chassis 21 by vertical slides 221 fixed inside the chassis.
  • the apparatus comprises a rotary shaft 25 which is introduced into the crucible.
  • This shaft 25 is suspended from the movable carriage 22 and it is rotated by the motor 23. about a vertical axis corresponding to the axis of symmetry of the crucible.
  • the rotary shaft 25 has at its lower part radial arms 26 fitted at their ends with percussion weights 27.
  • the lifting mechanism is for example constituted by cables 241 winding on return pulleys 242 and winched by a motor mechanism 243. Tensioners 244 are provided on the cables.
  • the centering of the chassis on the rim of the crucible is ensured by centralizers. Its upper part of the oven is called water-jacket.
  • the device is placed in a hoist on the upper part of the oven.
  • the device thus deposited is centered by the centralizers, placed at 120 ° on the periphery of the Water-Jacket.
  • the commissioning of the device consists in switching on the installation.
  • the motor 23 rotates at a constant speed and has a torque limiter which makes it stop and go back when the force is too great.
  • control member 243 allows the carriage 22 to be held in all the positions of the scouring.
  • the weight of the carriage combined with the weight of the motor helps the work. When the slag is hard to take off, it is sufficient to slightly loosen the cable suspension system.
