Definitions

  • the present invention relates to an emergency shutter of a supply device and pouring tube exchange applied sealingly against the fixed underside of a refractory reference plate housed in the frame of the device fixed to a container of metal pouring from the bottom, under the upward push of guide rails which determine a rectilinear trajectory along which the pouring tubes slide, under the action of a jack, from a loading position to a service in the casting axis and from the service position to a position of release.
  • Removing the blind plate was, however, a relatively straightforward operation. complicated due to the extreme temperatures prevailing near the axis of risk of forgetting to put it back in place or losing it in the mold by a wrong maneuver during preparations for loading the tube replacement.
  • the present invention aims to facilitate the establishment and removal of a plate shutter refractory during and after the pouring tube change operation of a continuous casting installation. To this end, it offers a shutter Emergency of the type described in the preamble to claim 1 attached.
  • This shutter is characterized in that it consists of a plate on which is deposited a blind refractory plate to be moved along a second path which intersects the first aforementioned trajectory, from a positioning position availability outside the second trajectory to an alert position on the right a trajectory overlap zone, adjacent to the service position of a pouring tube in the pouring axis.
  • the aforementioned trajectories are parallel to the fixed underside of the reference plate and included in the same plane horizontal.
  • the movable plate is a rotating plate by means of a rotary arm articulated to a frame of the supply and exchange device pouring tubes, around a vertical axis.
  • the movable tray is a tray-drawer sliding along straight guides fixed to the frame parallel to the plate reference refractory.
  • the movable plate is provided with a handle and / or a drawer or handle more accessible to an operator than the movable tray itself to manually operate it.
  • a supply and exchange device 2 of pouring tubes without however representing the mold in which should have immerse the pouring tube 3 shown in the service position in the casting axis.
  • This tube 3 is attached to a plate 4 applied sealingly against a lower face fixed of a reference refractory plate 5 applied against the frame of the device 2.
  • a upward pushing force is exerted on the plate 4 by guide rails 6 and 7.
  • the fixed guides 19 and 20 determine a first trajectory of the tube replacement and the tube to be replaced.
  • a blind refractory plate 8 which adjoins the tube 3 in the service position in the casting axis.
  • the plate shutter 8 is at work to be instantly moved under the push a retractable arm 9 of a pneumatic cylinder, as described in the patent EP-B-0192019, in the casting axis, to replace the pouring tube that it has itself pushed back by pressing along a common transverse rim.
  • a complete closure device 10 incorporated into the frame of the supply device and exchange of pouring tubes in the immediate vicinity of the guide rails 6, 7 is capable to deposit and remove, at will, the blind refractory plate 8 from a positioning position on availability 14 to an alert position 15 connected to the service position and vice-versa.
  • the shutter 10 consists of a movable plate 11 on which the blind refractory plate 8.
  • the movable plate 11 moves the blind refractory plate 8 along a second trajectory which intersects the above-mentioned first trajectory, from a standby position 14 outside the second trajectory towards a alert position 15 in line with an overlap zone of the two trajectories, adjacent to the service position of a pouring tube in the casting axis.
  • the plate mobile 11 is a tray-drawer sliding along rectilinear guides 12 and 13 fixed to the frame of the device for supplying and exchanging pouring tubes.
  • the movable platform is provided with a handle 17 and a drawbar or handle 18 more accessible to an operator than the movable plate 11 itself for manually actuating it.
