Definitions

  • the present invention relates to a slag cleaning device for foundry furnace crucibles according to the preamble of the claim.
  • Publication EP-A-0 148 711 describes an apparatus for removing slag from a crucible in which a shaft driven in rotation is driven back and forth under the action of a vibration generator. The vertical movement of the shaft is achieved by a control arm.
  • the publication US-A4 511 125 describes an apparatus for removing slag deposited in a crucible in which a carriage suspended by a cable system from a chassis fixed to the crucible, moves along this chassis. This carriage non-rigidly carries vibrating arms, the lower end of which allows percussion to be removed 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 equilibrium of the refractory and to a gain in rammed earth. Health and safety conditions are improved.
  • the subject of the invention is another cleaning device.
  • 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 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 mobile 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 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 set up with the 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 23 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 relax the cable suspension system.
