Definitions

  • the cast product is guided at the outlet of the mold by two parallel rows of rollers.
  • the guiding device has been divided into segments, each segment or cage being formed from a chassis carrying several rollers from each row and fixed to a supporting chassis.
  • Different means have been proposed for setting up the cages on the carrying frame and for dismantling them.
  • the present invention relates to curved continuous casting installations in which these means consist of two fixed rails arranged radially, on either side of each cage, the sides of which are provided with rollers engaged in these rails, and a device for lifting to move the cages along the rails.
  • a first solution consists in dismantling the cages by moving them outwards, that is to say, away from the center of curvature of the installation.
  • This solution is expensive because it requires a support frame of complicated construction.
  • Another solution is to mount one of the end rollers of the outer row of each cage so that it can be disassembled on site to allow disassembly of the cage. This solution complicates the replacement of the segments since it is necessary to disassemble the removable roller in order to be able to remove the cage, and, after the installation of a new cage, fix this roller on the latter.
  • the present invention proposes to provide a simple solution to this problem allowing easy and rapid replacement of the cages.
  • the device which is the subject of the invention is characterized in that the rails for removing the cages each comprise at least one portion inclined with respect to the general radial direction of the rail and situated so as to cause, during the movement of a cage on these rails, a tilting of the cage to place it at an angle and allow it to cross in this position the passage limited by the extreme rollers of the inner row of the two cages adjacent to the dismantled cage.
  • each rail will have two portions inclined in opposite directions and cooperating respectively with the inner and outer rollers of the cage to cause the latter to tilt.
  • the continuous casting installation shown in Figure 1 comprises a support frame 10 consisting of curved beams of large section resting on supports allowing their expansion.
  • the chassis 10 supports the ingot mold 12 and the device for guiding the cast product consisting of two parallel rows of horizontal rollers defining between them a curved passage for the cast product.
  • the row closest to the center of curvature of the installation and therefore having the smallest radius of curvature is called the interior row; the other row with the greatest radius of curvature is called the outer row.
  • This guide device is formed by several segments which can be dismantled and replaced individually.
  • the upper segment 14 can be removed from above, by means of an overhead crane, after removing the mold.
  • each of them there are provided, on each side of each of them, guide rails 18 arranged radially, that is to say in a direction parallel to the radii of the arc of a circle that constitutes the axis of the passage defined by the two rows of rollers. Rollers 20 mounted on the sides of the segments are engaged in these rails which generally have a U-shaped section, and a winch 22 carried by a carriage 24 movable on a raised raceway makes it possible to disassemble the segments by moving them along the rails 18.
  • the rails 18 are connected to vertical rails 18 ′ and the carriage 24 is also provided with vertical rails 26 which can be brought into alignment with any of the 18 'rails.
  • the dismantled segment can thus be easily transferred to the trolley and transported by it to the repair and maintenance workshop and a new segment can also easily be put in place.
  • the segments In the installation shown in FIG. 1, the segments have a substantially rectangular section and can be disassembled without problem by moving them radially along the rails 18.
  • Each rail 18, the general direction of which is that of a radius of the arc of a circle of center 0 constituting the axis of the passage delimited by the two rows of rollers, comprises, moving from the chassis 10 towards the center 0, a first radial portion a - b, a portion inclined to the left b - c, a portion inclined to the right c - d, a second radial portion d - e, a portion inclined to the right e - f, a portion inclined towards the left f - g and a third radial portion g - h; the successive portions are connected together by curved portions of sufficient radius to allow the rollers 20 to roll on the rails.
  • the successive positions of the segment during disassembly are shown in Figure 2.
  • the successive positions of the outer and inner rollers 20 are indicated in A, B, C, D and A ', B', C ', D', respectively.
  • the length, the inclination and the position along the rails 18 of the inclined portions b - c and e - f depend on the dimensions X and Y and on the spacing between the two rows of rollers; they can be straight or curved.
