Definitions
- the invention relates to a casting device comprising a metallurgical container provided with an orifice casting, especially a converter for the elaboration steel; a slide shutter for said orifice casting, said shutter comprising: at least one fixed refractory plate having an orifice placed opposite the pouring orifice; at least one refractory plate mobile having at least one orifice; of the moving means for moving the movable plate relative to the fixed plate so as to control the covering the holes of the fixed plate and the plate mobile; pressure means which make it possible to tighten the movable plate against the fixed plate.
- FR-A-2 436 923 is a shutter with a shutter plate solid or having a through hole for the metal.
- This shutter plate is disposed between two plates, respectively an upper plate and a lower support plate on which is fixed a pouring tube.
- the top plate is a work plate.
- the shutter plate rubs against its underside with each movement of the drawer. This face is thus eroded relatively quickly which requires changing the upper plate at each change of the sealing plate.
- JP-49-105730 a device for assembling a set of refractory plates without a casting vessel. This device does not have planar function surfaces.
- a device for the replacement of refractories used to transfer liquid steel from a dispatcher to a casting mold has a junction plate, mounted at the end of the tundish orifice, and at least two sets each consisting of a fixed plate and a movable plate secured to a tube of casting. These assemblies are mounted on guide rails, so that a used refractory set can be replaced by a new set, one chasing the other.
- Such a device is provided for replacement refractories during casting, and not between two flows. It can not therefore allow access to the plate junction in order to check it and possibly to change.
- a set of new refractories is introduced on one side of the pouring orifice, while the used refractory assembly is evacuated from the opposite.
- the introduction of refractories must be done alternately on one side then the other of the pouring orifice.
- the device thus requires three distinct zones, namely an introductory zone new refractories, a casting zone, and a zone evacuation of used refractories. Its size is therefore at least equal to three lengths of plates.
- the device does not describe any means to put the refractories in place and remove them easily.
- the present invention relates to a device casting and a method of implementing this device who solve these problems.
- the present invention also relates to the use of a plate according to claim 16.
- the device comprises a surface substantially extending the surface of the connection of the pouring orifice in the introduction / extraction zone, in order to ensure pre-guidance of the fixed plate relative to the junction surface of the pouring orifice to facilitate placement and / or removing at least the fixed plate by sliding on the joining surface.
- junction surface of the orifice casting and the joining surface of the fixed plate are planar.
- the flatness of these two surfaces also makes it easier to in place and / or removal of the fixed plate by sliding on the joining surface of the pouring orifice.
- the surface of junction of the pouring orifice consists of a plate refractory. This plate is changed between two when the container is empty and the steel is not do not run. It is therefore impossible for steel to penetrate between this junction plate and the fixed plate.
- the guide surface should be exactly the same level as the joining surface. But this is not mechanically feasible because machining tolerances.
- the level of the surface of guidance is therefore equal by default (ie to the tolerances machining near) at the joining surface of the pouring orifice, a chamfer being provided for facilitate the placement of the fixed plate on the surface junction of the pouring orifice.
- the pressure means for tighten the joining surface of the fixed plate against the junction surface of the pouring orifice are arranged to act during set-up and / or removal by sliding at least the fixed plate to eliminate the waste possibly remaining on this surface.
- Means of travel to implement place and / or remove the fixed plate by sliding on the junction surface of the pouring orifice are preferably the same as the means to move the plate mobile relative to the fixed plate.
- the device preferably comprises: a frame; a frame for driving the fixed plate; a frame driving the movable plate; moving means the drive frame of the movable plate, these means constituting the means of displacement of the movable plate mentioned above; of the means of securing the training framework of the fixed plate either with the frame or with the training frame of the movable plate.
- the means for securing the drive frame of the fixed plate with the frame or with the drive frame of the movable plate are, in a preferred embodiment, constituted by a two-position latch mounted on the drive frame. of the fixed plate, this lock immobilizing the drive frame of the fixed plate relative to the frame in a first position and relative to the drive frame of the mobile platform in the second position, the moving means of the drive frame the movable plate having a sufficient stroke to move all of the two frames to release the fixed plate of the grip of the pressure means of the fixed plate against the junction surface of the casting orifice.
- the device comprises a fixed stop relative to the frame against which the fixed plate comes into abutment at the end of introduction, the lock comprising means for recovering clearance to lock said fixed plate against the stop via the frame of drive of the fixed plate so that the fixed plate and the drive frame of the fixed plate are together immobilized relative to the frame.
- the clamping means of the fixed plate against the junction area of the pouring orifice are preferably the same as the pressure means for press the movable plate against the fixed plate.
- the joining surface of the pouring orifice may consist of a refractory plate surrounding the pouring orifice mounted on a metal support allowing to ensure a rigid fixation of said refractory plate on the metallurgical container.
- the metal support may have at least a portion of co-planar surface with the refractory plate in order to enlarge the support surface of the fixed plate on the junction surface of the pouring orifice.
- Plots made of a material compatible with that of the refractory plate from the point of view of machining by the same tool can be rigidly attached on the metal support and machined co-planar with the refractory plate so as to enlarge the support surface of the fixed plate against the joining surface.
- At least the fixed plate is brought and / or withdrawn laterally with respect to the cast and slid under pressure prior the fixed plate does not begin to cover and / or discover the pouring orifice of the container.
- FIG. 1 shows an overall view of the casting device.
- the metallurgical container is designated by the general reference 1.
- This container can be a dispatcher, or a pocket, or as in the example shown, a converter for the development of steel.
- a slide shutter, designated by the general reference 10 is fixed under the container. The steel contained in the converter is poured into a pocket 3.
- FIG. 2 shows a schematic view in section of the device.
- the steel wall 2 of the container is covered by a protective layer 4 of refractory material, for example bricks.
- a taphole 6 allows the exit of the metal out of the converter.
- the hole of this hole is delimited by a surface outer 8, flat in the example shown. This surface 8 constitutes a joining surface.
- the slide shutter 10 fixed under the container consists of a frame 12 fixed on the outer wall 2 of the metallurgical container.
- a set two plates namely a fixed plate 14 and a movable plate 16.
- Each of the plates comprises one or more holes for the passage of the metal and is surrounded by a frame, respectively 20 and 22. These two plates are enclosed in a housing 24.
- pressure means schematically represented by the springs 26 allow to press the fixed plate 14 against the movable plate 16.
- An actuating means such as a hydraulic cylinder 28, whose rod is connected to the frame 22 of the movable plate can move the movable plate relative to the fixed plate. This displacement allows, in known manner, to vary the recovery holes of the two plates so to control or stop completely the passage of the metal.
- the drawer includes only two plates, it could include more, for example three or more.
- the housing 24 is in turn pressed by pressing means 30 against the surface 8, which ends the pouring orifice so that the back of the plate fixed, which has a fitting surface 32 adapted at surface 8 be applied sufficiently strongly to create a metal seal.
- Surface qualities in the presence of course are of sufficient quality to ensure this tightness.
- the joining surface must be large enough so that means pressure do not exert effort cantilever. Since the pressure means to tighten against each other the fixed plate and the movable plate are different pressure means for pressing the surface of joining the fixed plate against the surface of junction of the pouring orifice, it is possible to vary pressures per unit area independently one from the other.
- the guiding surface 34 may be slightly behind this plan, as shown in fig 2.
- a chamfer will be then provided on the fixed plate or on the joining surface to facilitate the installation of the fixed plate in absorbing the difference in level.
- FIGS. 3 and 4 show another mode embodiment of a casting device according to the invention.
- This device comprises a solid frame 12 fixed on an outer wall 2 of the metallurgical container.
- a plate of junction 36 reported and cemented on the end of the hole casting.
- the outer surface of this plate 36 constitutes the junction surface 8.
- the fixed plate is here consisting of the refractory plate itself and a envelope 38.
- the movable plate consists of the plate refractory itself, a support 40 and a nozzle collector 42, separate or made in one piece with the refractory plate.
- the means of pressure 26 will be described in more detail with reference to FIG. Note, however, that in this embodiment the clamping means of the fixed plate against the surface junction of the pouring orifice are the same as the pressure means for pressing the fixed plate 14 against the movable plate 16. The same means fill therefore two distinct functions.
- the fixed plate is placed in the training frame of the fixed plate 20 and the movable plate in the drive frame of the movable plate 22.
- the rod 44 of the cylinder 28 is retained in a frame housing driving the movable plate 22.
- the cylinder 28 allows to move the movable plate on the fixed plate of in a manner known to control the flow metal out of the metallurgical container.
- FIG. 4 shows a sectional view of the embodiment shown in FIG. perpendicular cutting plane.
- This figure shows in particular the details of the designated means of pressure as a whole by the general reference 26. They comprise a helical spring 46 having one end is resting on the frame 12 and the other on a rocker arm 48. The rocker transmits the action of the spring, in the sense reverse, on the moving plate. Action on the mobile plate is retransmitted to the fixed plate, then to the junction plate 36.
- a latch 50 with two positions.
- This lock is rotatably mounted on the training frame 20 of the fixed plate. In a first position, shown in fig 3, he enters a dwelling 51 of the frame 12. In its other position it penetrates in a housing 53 provided in the training frame of the movable plate 22. In the first position it immobilizes the drive frame of the fixed plate relative to the frame and, in its second position, relative to to the drive frame of the movable plate.
- the cylinder 28 has a stroke sufficient to move all of the two frames enough to release the fixed plate of the right of way of the pressure the fixed plate against the junction surface of the orifice casting.
- the same medium namely the cylinder 28, performs successively two distinct functions.
- it allows to move the moving plate (first position of the latch 50).
- it serves to extracting the part to be changed and setting up a new fixed plate.
- the lock is placed in his second position. The action of the jack allows then move the fixed plate and the plate in a single block mobile, secured together by the lock 50.
- a fixed stop 52 is provided on the frame 12.
- the fixed plate 14 bears against this stop 52 at the end of its introduction.
- the latch 50 has a surface 54 constituting means of catching up play to lock the fixed plate against the stop 52 via the drive frame of the fixed plate.
- This surface 54 is for example a surface constituting a helical cam. So the fixed plate and the frame drive the fixed plate are together immobilized without play compared to the frame. This provision is intended to prevent relative movement of the plate fixed relative to the joining surface. Indeed the movable plate transmits sharp forces to the plate fixed. Such efforts, which are important, tend to move the fixed plate. If it was not blocked, she would move relative to the surface of junction of the pouring orifice, which would have the consequence detrimental wear of the surfaces in contact of the fixed plate and the joining surface.
- FIG. 5 shows a variant of realization of the drawer of Fig 3 in the open position.
- the parts of the same kind are designated by numbers identical reference numbers.
- the lock 50 is placed in said second position in which it secures the training frame 20 of the fixed plate 14 with the drive frame 22 of the movable plate 16.
- the jack 28, whose rod 44 is connected to the frame 22 of the mobile plate, was used to push the set constituted by the two training frames (fixed and mobile) and the plates housed in the openings of these frames (fixed plate 14 and plate mobile 16). This movement has been pursued sufficiently so that the fixed and mobile plates are entirely freed from the action of pressure this way they can be removed freely without have to open a door like this is usually done in the devices of the prior art.
- the installation of new plates is carried out in the same way.
- the fixed plate 14 is first placed inside the opening of the training frame 20 of the fixed plate on a bearing surface of frame 12 located (with close machining tolerances), in the extension of the joining surface.
- the moving plate is then placed on the fixed plate, inside the opening of the drive frame 22 of the movable plate. It is not necessary to connect or disconnect because the cylinder rod remains fixed, during these operations, on the drive frame of the plate mobile.
- the cylinder is then actuated to pull the assembly which penetrates laterally with respect to the pouring orifice under the locking means 50, which immobilizes the two plates without further operation.
- the fixed plate 14 is brought and / or withdrawn and slid under pressure means 30 prior to this that the fixed plate 14 does not begin to cover the orifice casting of the container.
- FIGS. 6 and 7 show two variants embodiment of the junction plate.
- the junction plate of the pouring orifice is constituted a refractory plate 56 surrounding the pouring orifice.
- the plate 56 is secured to a metal support 58 to ensure a rigid fixation on the container metallurgy, for example by means of screws, bolts, studs or the like arranged in the holes 60.
- the surface of the metal support 58 is co-planar, at less in part, with the joining surface 8. This may be obtained by a correction of these two surfaces after assembly of the refractory plate on the support metallic.
- the surface of the metal support 58 allows to enlarge the support surface of the fixed plate on the surface junction and avoid a cantilevered plate fixed.
- Plots 62 are fixed rigidly on the support 58 metal and co-planar machined with refractory plate 56 so as to enlarge the bearing surface of the fixed plate 14 against the joining surface 8.
- the pads 62 are made of a material compatible with that of the refractory plate 56 from the point of view of machining.
- the pads 62 are made in the same refractory material than that of the plate 56. Thus it is possible to machine them simultaneously without difficulty.
