Definitions

  • the present invention relates to a device for regulation of a continuous flow rate under a ladle casting, which device comprises a push cover containing a fixed upper plate and mounted on a frame rectangular metal, arranged to pivot relative to a bottom wall of the ladle and carrying a carriage provided with means for guiding a pouring tube applied against a movable plate in tight contact with the upper plate fixed, the two plates being pressed against each other by pressure devices, the moving plate and the tube casting can be moved simultaneously from one position shutter to an open position of the tap hole and vice versa.
  • a metal frame for sliding closure device a metallurgical container for continuous casting mainly comprising a base plate integral with the metal container and a pivoting door articulated on the base plate.
  • Removable rotation hinges and device removable door lock on the plate base allow easy access to parts wear, at the same place where the steel is poured.
  • a device pressure tap is provided to apply the plate movable against the fixed plate while the tube casting is held removably against the plate mobile.
  • a disadvantage of this known device lies in the fact that the movable plate is clamped between two elements fixed. Such a movable plate therefore has two sliding surfaces, the first face being sliding relative to the top plate of the tube of casting and the second in relation to the added plate of the pouring tube.
  • a sliding closure device for a container bottom pouring including a push cover held in place by a mounted metal frame pivoting relative to a bottom wall of the container casting to facilitate access to the refractory plates wear.
  • the push cover contains a top plate fixed and a carriage carrying a pouring tube forming body with a movable refractory plate in contact with the fixed upper plate.
  • the top plate is subjected to a rectification. This operation ensures the flatness of the surface but not constant or precise thickness of the top plate.
  • the present invention aims to reduce the number wear elements in sliding contact during adjusting the flow and improving the supply and exchange of a pouring tube under a ladle or under a flow distributor without having to modify notably the speed of extraction of the slab, bloom or billet.
  • the present invention provides a articulated frame for flow control device pouring to bring and exchange a tube as described in the first paragraph of the descriptive memory.
  • the articulated chassis is essentially characterized in that pressure devices consist of prime and second pushing means, the first pushing means being downward pushing means which apply the upper plate against a reference plane constituted by the movable plate and the second thrust means being of upward pushing means acting independently of means of pushing down, on guides which apply the pouring tube against the movable plate, following the movement of the movable plate between its closed positions and opening the tap hole.
  • pressure devices consist of prime and second pushing means, the first pushing means being downward pushing means which apply the upper plate against a reference plane constituted by the movable plate and the second thrust means being of upward pushing means acting independently of means of pushing down, on guides which apply the pouring tube against the movable plate, following the movement of the movable plate between its closed positions and opening the tap hole.
  • the push cover is articulated on the metal frame around second pivots.
  • the device pressure of the fixed upper plate against the movable plate consists of two series of cartridges spring loaded on either side of the hole pouring along opposite sides of the top plate fixed.
  • the spring cartridges are retained in place by a removable removable compression plate on the pusher cover using studs.
  • the originality of the supply and exchange system pouring tube according to the invention resides in the fact that the tube change is done by sliding against the underside of a movable plate forming a system drawer closure with two plates, without however forming a three-plate system as described in particular Belgian patent nr 896,223.
  • the device according to the invention offers the advantage of make it possible to adjust the steel flow by translation a movable part of the sliding closure device without the tube changing device itself does not move under the movable plate. We thus avoids any deterioration of the joint between the plate mobile and the sinking tube due to friction or infiltration steel.
  • the displacement of the pouring tube following a movement crossed, i.e. in two perpendicular directions between them has the advantage of allowing the implementation of first means of training fast and large, but imprecise for bringing the pouring tubes in the immediate vicinity of the tap hole and second drive means perpendicular to the first, of small amplitude, but very precise for adjusting the flow.
  • This mounting method not only allows the supply and the exchange of a pouring tube, but also easy replacement of wearing parts such as the plate fixed upper as well as visual examination of the internal nozzle.
  • a closing device sliding 1 which carries out the supply and the exchange of a pouring tube 2 and the regulation of the flow of a ladle 3 includes a rectangular metal frame 4 arranged to be able to pivot relative to a bottom wall 5 of the ladle 3 around a on its sides by means of the first horizontal pivots 6 arranged transversely to the direction of movement of the movable plate 10 within sight to regulate the flow rate.
  • the first pivots 6 are engaged in lugs 30 fixed on the bottom of the ladle 3.
  • the metal frame 4 supports a push cover 7 containing a fixed upper plate 8 and a carriage 9 carrying the movable plate 10.
  • the upper plate 8 is pressed down by a pressure device 12 consisting of two series of spring cartridges 13, 14 arranged on either side tap hole 15 along opposite sides of the plate fixed upper 8.
  • Spring cartridges 13, 14 are retained in place by the studs 17. They are subject compression preload, before the chassis 4 is raised and locked.
  • the movable plate 10 is subjected to a thrust downwards transmitted by the fixed upper plate 8 pushed down by a series of cartridges to spring 13, 14 and it is also subjected to a thrust upwardly exerted by the pouring tube, subjected to the action of the pushing devices 31, which act independently of the cartridges 13, 14.
  • the plate mobile 10 is therefore compressed between the upper plate fixed 8 and a flange 11 of the pouring tube 2.
  • the push-button cover is hinged to the metal frame 4 7 arranged to pivot down around second horizontal pivots 18.
  • the carriage 9 comprises guide means 19, 20 of the pouring tube 2 erected vertically.
  • the guide means 19, 20 extend in a horizontal plane. They bring the replacement pour tube 2 from a loading position 21 located far from the tap hole to a standby position 22 located just below the casting hole 27 on the plate mobile 10 when it is in position sealing the tap hole.
  • the means of pushing 31 are pushed upwards by articulated levers 35 at 36 and subjected to the action of springs 37 at their end free 38.
  • first and second pivots 6, 18 are parallel to each other. They determine an axis of rotation L L perpendicular to the direction of travel according to arrow X of the two-plate drawer formed by the fixed upper plate 8 and the movable plate 10 when regulating the steel flow.
  • the double articulated chassis 4 simply facilitates access to refractory parts, in particular to the movable plate 10.
  • Assembly and disassembly of the articulated chassis 4 a device for supplying and exchanging a pouring tube 2 and regulating a ladle 3 on the bottom wall 5 of a ladle 3 is made as following.
  • an internal nozzle is positioned 23 in a seat brick 24 of the ladle 3 from below.
  • Two series 13, 14 of cartridges are retained in place spring loaded using a compression plate 16 removably attached to the top plate 8 using studs 17.
  • spring cartridges are compressed 13, 14 using a hydraulic tool not shown leaning on the compression plate 16 and the compression plate 16 is locked using anchor pieces comprising a wing nut 40. In releasing the hydraulic tools, the plate is released higher.
