Definitions

  • the invention relates to a sliding closure device for a steel or metallurgical container consisting of a support frame comprising a fixed upper plate, itself formed of at least one refractory element provided with at least one pouring orifice and possibly maintained in a metal frame, and at least one sliding plate, optionally removably mounted in a slide, so as to slide relative to the fixed upper plate against which it is applied.
  • the sliding closure device according to the invention can in particular be mounted on a continuous casting distributor for the manufacture of blooms and small slabs.
  • the present invention relates to a method and a device making it possible to avoid the abovementioned drawbacks. It proposes to make the closure device independent of the container, to allow the replacement of the refractories independently on each line, while retaining a good seal in the runner.
  • a sliding closure device for a steel or metallurgical container consisting of a support frame comprising a fixed upper plate, itself formed of at least one element. refractory provided with at least one pouring orifice and possibly maintained in a metal frame, at least one sliding plate optionally removably mounted in a slide, so as to slide relative to the fixed upper plate against which it is applied.
  • This device is essentially characterized in that it makes it possible to separate at least one element from the upper plate, removably mounted on said device before it is placed under the container, so that the plate element which is separates from the device remains integral with the container when, during an interruption of the casting operation, the device is moved away from said container.
  • each above-mentioned upper plate element only represents part of the sliding surface with respect to each movable plate
  • the sliding face of each element of the upper plate with respect to the sliding plate is held against reference supports formed in the walls of the support frame by means acting on the back of each plate element.
  • the upper plate advantageously has at its upper part a boss constituting an internal nozzle intended to penetrate into the seat brick.
  • the aforementioned boss of the upper plate is preferably porous to gases and is provided with a gas supply arranged in the upper plate for injecting gas, in particular inert, into the pouring channel through the porous boss of the upper plate.
  • the device comprises two sliding plates brought alternately under the pouring orifice of the upper plate by translation in the opposite direction.
  • the device according to the invention comprises a cam which extends symmetrically with respect to an end plane passing through the casting axis, on which acts at least one spring disposed symmetrically with respect to the above-mentioned plane and along from which slides at least two levers mounted on a carriage and intended to apply each of the aforementioned plates against the sliding plane of the upper plate, so that the pressure increases when any of the plates approaches the pouring orifice and decreases when it deviates from it, allowing easy removal of the aforementioned plate in the rest position.
  • the device advantageously comprises, in the pouring axis and under the lower movable plates, a lower plate possibly attached to a jet protection tube which possibly dips in the mold and held in place in a fixed lateral position against the underside of the other movable plate using a movable support fork in a vertical plane.
  • the sliding closure device designated as a whole by the reference notation 1, consists of a main frame 2 comprising an upper fixed plate 3 mounted in a fixed assembly 4, a carriage or slide 5 on which is removably mounted at least one movable plate 6,7 of refractory material.
  • the upper fixed plate 3 is optionally formed of several independent elements 8, 9 and 10, one of which is provided with a boss acting as an internal nozzle 11 and forms an internal nozzle-upper plate element 12 assembly provided in a single sheet 13.
  • This assembly 13 is deposited on the support frame 2 and is held in place using a retractable blocking device 14 which can be removed even when the closure device is put in place under a container 15.
  • This implementation is carried out simply by approaching the sliding closure device 1 of the container 15 so as to introduce the internal nozzle 11 into a seat brick 16, mounted by the interior side of the container 15 during the preparation of the refractory lining 17
  • the positioning of the seat brick 16 is ensured by a metal centering ring 18 fixed to the bottom of the container.
  • the closing device can be handled using an individual motorized or manual forklift.
  • the sliding closure is fixed using, for example, four eyelet bolts 19 tightened on lugs 20 welded to the container 15.
  • the sliding surface 21 of the above-mentioned upper plate 3 must preferably be large in order to ensure in said sliding closing device, a sufficient bearing stroke for the movable plates 6,7.
  • the machined working face 21 or the sliding face of the plates 8, 9 and 10 are used as positioning reference and not, as is generally the case, their back.
  • the method of attachment described makes it possible to mount the closure device 1 on a container 15 just before casting and to remove it just after.
  • a clamping device 24 applies the carriage or slide 5 provided with the movable plate (s) 6 (7) against the upper fixed plate 3, so as to obtain a sealed contact in the casting zone.
  • each movable plate 6, 7 is carried by an independent fork 25 articulated in all directions to allow perfect application of said movable plate 6,7 against the sliding plane of the upper fixed plate 3, which transmits the pressure force against the upper fixed plate 3 by means of a lever 26.
  • the above-mentioned pressure force is transmitted to the lever 26 by the clamping device 24 illustrated in FIGS. 2 and 4, consisting of a substantially horizontal tilting bar 27, held laterally by two axes 27 ′ introduced into elongated orifices 28 and by a housing 28 'so as to be able to oscillate and slide in a substantially vertical plane with a play of a few millimeters and repelled by at least one spring 29 acting in the vicinity of its midpoint.
  • the force exerted by the tilting bar 27 on one or more rocker (s) 30 moving simultaneously along said tilting bar 27 will increase as a pad 30 'of the rocker arm 30 will approach the point or area of application of the spring (s) 29.
  • a low residual pressure makes it easy to extract and replace a used plate 6 in the waiting area.
  • the device allows the mobile plate 6,7 intended for a particular use to be put in place, such as a calibrated orifice for starting a line of the continuous casting installation or even a closing plate 7.
  • the linear movement of the carriage 5 is ensured by a device of the threaded rod-nut type.
  • the threaded rod 32 is rotated by an electric motor 33 on which is mounted a speed reducer 34. It is advantageous to provide two speeds, the slow speed allowing precise rolling of the jet of liquid metal, the other allowing a change quick of the above plate.
  • the drive nut 35 is advantageously carried by a U-shaped piece intended to move the carriage 5 by acting on one side or the other, so that the reserve plate 7 pushes the plate in service 6
  • This design makes it possible to avoid any infiltration of liquid metal, in particular when the line of separation of the plates passes in front of the pouring orifice 31.
  • the threaded rod 32 is advantageously surrounded by an expandable device of conical shape forming a protective sheath 32 'around the threaded rod 32.
  • the closing device 1 comprises, under the movable plate 6 in the working position, in the extension of the axis of the pouring channel 30, a pouring tube 36 secured to a lower plate 37 held in place by a support fork. 38, pivoting in a vertical plane, around the point of application of a lever 38 '.
  • This support fork 38 is held in the high position by a set of four springs 39, fixed by the bolts 40, thus making it possible to strongly apply the lower plate 37 against the lower face of the movable plate 6.
  • the action of the above-mentioned springs 39 is counterbalanced by jacks 41.
  • a movable closing plate 7 is brought by sliding along the upper 3 and lower 37 fixed plates, opposite the pouring orifice 30.
  • the support fork 38 supporting the pouring tube 36 is lowered by means of pneumatic cylinders 41 acting against the springs 39.
  • the pouring tube can then be removed manually using the fork 42 and replaced by a new tube.
  • the aforementioned fork 42 is advantageously articulated so that it is easy to remove the lower plate and the pouring tube without raising the container 15 or the distributor. This ensures independence for the various casting lines total lines between them.
  • each jack 41 is for example constituted by a metal bellows closed at its ends by the metal flanges 43.
  • One of the metal flanges is provided with a supply of gas 44 under pressure making it possible to actuate the pneumatically cylinder.
  • the internal nozzle 11 is made of a porous material for gases and is provided with a gas supply formed in the upper plate 3 for injecting gas, in particular inert, into the pouring channel 31 through the porous boss 11 of the upper plate 3 .
  • the sliding closure device allows the implementation of a one-piece assembly comprising a bottom plate and a pouring tube incorporated therein. It allows the replacement of such a possibly defective assembly by a new assembly without the need to interrupt the casting or to raise the distributor.
  • the monobloc assembly described above has the advantage of having no seal.
  • the device according to the invention therefore makes it possible to obtain effective protection of the pouring joint, since it only involves connections made up of two plates applied one against the other. These flat connections generally have an excellent seal and are capable of being easily inertized.
