Definitions

  • the invention relates to a casting device comprising a metallurgical container provided with a pouring orifice, in particular a converter for the production of steel; a slide shutter for said pouring orifice, this shutter comprising: at least one fixed refractory plate having an orifice placed opposite the pouring orifice; at least one movable refractory plate comprising at least one orifice; displacement means for moving the movable plate relative to the fixed plate so as to control the covering of the orifices of the fixed plate and of the movable plate; pressure means which allow the movable plate to be clamped against the fixed plate.
  • Casting devices of this type are already known.
  • the fixed plate of the slide valve is cemented at the end of the pouring orifice outside the container.
  • the end of the pouring orifice is coated with cement, and the fixed plate is pressed against this end.
  • FR-A-2 436 923 a drawer shutter provided with a full shutter plate or having a through hole for the metal.
  • This closure 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 present invention relates to a casting device and a method of implementing this device which solve these problems.
  • junction surface of the pouring orifice and the junction surface of the fixed plate are planar.
  • this characteristic is not essential, the flatness of these two surfaces facilitates the positioning and / or removal of the fixed plate by sliding on the junction surface of the pouring orifice.
  • the junction surface of the pouring orifice consists of a refractory plate. This plate is changed between two castings while the container is empty and the steel does not flow. It is therefore impossible for steel to get between this junction plate and the fixed plate.
  • Preferably means are provided to facilitate the positioning and / or removal of at least the fixed plate by sliding on said planar junction surface.
  • These means to facilitate the introduction and / or removal of at least the fixed plate can be constituted by at least one guide surface on the side of the introduction of the fixed plate, a surface which substantially extends the junction surface of the pouring orifice so as to ensure a pre-guiding of the fixed plate with respect to the junction surface of the pouring orifice.
  • the guide surface should be exactly at the same level as the junction surface. However, this cannot be done mechanically because of the machining tolerances.
  • the level of the guide surface is therefore equal by default (that is to say, to the machining tolerances) at the level of the junction surface of the pouring orifice, a chamfer being provided to facilitate positioning. place the fixed plate on the junction surface of the pouring orifice.
  • the pressure means for clamping the junction surface of the fixed plate against the junction surface of the pouring orifice are arranged so as to act during the positioning and / or the sliding removal of at least the fixed plate in order to eliminate the waste possibly remaining on this surface.

  • the means for securing the drive frame of the fixed plate either with the frame or with the drive frame of the movable plate are, in a preferred mode, constituted by a two-position lock 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 movable plate in the second position, the means for moving the frame drive of the movable plate having a sufficient stroke to move the assembly of the two frames until releasing the fixed plate from the grip of the pressure means of the fixed plate against the junction surface of the pouring orifice.
  • the device comprises a fixed stop relative to the frame against which the fixed plate abuts at the end of introduction, the lock comprising clearance recovery means for blocking said fixed plate against the stop via the drive frame of the fixed plate so that the fixed plate and the drive frame of the fixed plate are immobilized together with respect to the frame .
  • the means for clamping the fixed plate against the junction surface of the pouring orifice are preferably the same as the pressure means for pressing the movable plate against the fixed plate.
  • the junction surface of the pouring orifice can consist of a refractory plate surrounding the pouring orifice mounted on a metal support making it possible to rigidly fix said refractory plate to the metallurgical container.
  • the metal support may have at least a portion of surface co-planar with the refractory plate so as to enlarge the bearing surface of the fixed plate on the junction surface of the pouring orifice.
  • Studs made of a material compatible with that of the refractory plate from the point of view of machining by means of the same tool can be rigidly fixed on the metal support and machined co-planar with the refractory plate so as to enlarge the surface of the fixed plate against the junction surface.
  • the invention also relates to a method of implementing the device.
  • This method of replacing at least the fixed plate of said drawer obturator is characterized in that a cementless joint is produced between the pouring orifice of the metallurgical container and the fixed plate of the obturator by tightening a junction surface of the fixed plate against a junction surface of the pouring orifice.
  • At least the fixed plate is brought and / or removed laterally relative to the pouring orifice and slid under pressure means before the fixed plate begins to cover and / or uncover the casting member of the container.
  • FIG. 1 An overview of the casting device.
  • the metallurgical container designated by the general reference 1.
  • This container can be a distributor, or a pocket, or even, as in the example illustrated, a converter for the production of steel.
  • a drawer 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 a schematic sectional view of the device.
  • the steel wall 2 of the container is covered by a protective layer 4 of refractory material, for example bricks.
  • a tap hole 6 allows the metal to exit the converter.
  • the orifice of this hole is delimited by an outer surface 8, flat in the example shown. This surface 8 constitutes a junction surface.
  • the drawer shutter 10 fixed under the container consists of a frame 12 fixed on the outer wall 2 of the metallurgical container.
  • a frame 12 fixed on the outer wall 2 of the metallurgical container.
  • Each of the plates has one or more orifices for the passage of the metal and is surrounded by a frame, respectively 20 and 22. These two plates are enclosed in a box 24.
  • Pressure means represented schematically by the springs 26, make it possible to press the fixed plate 14 against the movable plate 16.
  • An actuating means, such as a hydraulic cylinder 28, the rod of which is connected to the frame 22 of the movable plate makes it possible to move the movable plate relative to the fixed plate. This movement makes it possible, in known manner, to vary the overlap of the orifices of the two plates so as to completely control or stop the passage of the metal.
  • the drawer has only two plates, it could have more, for example three or more.
  • the housing 24 is in turn pressed by pressure means 30 against the surface 8, which terminates the pouring orifice so that the back of the fixed plate, which has a junction surface 32 adapted to the surface 8 is applied strong enough to create a metal seal.
  • the qualities of surfaces present are of course of sufficient quality to ensure this seal.
  • the junction surface must be large enough so that the pressure means do not exert a cantilever force. Since the pressure means for clamping the fixed plate and the movable plate against each other are different from the pressure means for pressing the junction surface of the fixed plate against the junction surface of the pouring orifice , it is possible to vary the pressures per unit area independently of each other.
  • junction surface 8 is smaller than the fixed plate. This is why it is advantageous to provide means to facilitate the positioning and / or removal of at least the fixed plate by sliding on said planar junction surface.
  • These means consist of a guide surface 34. This surface is located on the side of the pouring orifice 6 through which the fixed plate must be introduced. It is located substantially in the plane of the junction surface.
  • the guide surface 34 may be slightly set back from this plane, as shown in FIG. chamfer will then be provided on the fixed plate or on the junction surface to facilitate the positioning of the fixed plate by absorbing the difference in level.
  • the housing 24 containing the used fixed and mobile plates is first removed by sliding them on the junction surface 8 and then on the guide surface 34 using the jack 28 until 'They are no longer subjected to the action of the pressure means 30. This has the effect of shearing the waste which is on the junction surface. In particular, if a steel ring has formed at the junction between the junction surface of the pouring orifice and the fixed plate, this ring will be sheared and the waste evacuated through the taphole 6. The housing is then disconnected from the cylinder rod 28 and removed.
  • FIGS. 3 and 4 show another 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 connecting plate 36 attached and cemented on the end of the tap hole.
  • the outer surface of this plate 36 constitutes the junction surface 8.
  • the fixed plate here consists of the refractory plate itself and an envelope 38.
  • the movable plate consists of the refractory plate itself, a support 40 and a collecting nozzle 42, separate or produced in one piece with the refractory plate .
  • the pressure means 26 will be described in more detail with reference to FIG. 4. It will however be noted that in this embodiment the means for clamping the fixed plate against the junction surface 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 therefore fulfill two distinct functions.
  • the fixed plate is placed in the drive frame of the fixed plate 20 and the movable plate in the drive frame of the movable plate 22.
  • the rod 44 of the jack 28 is retained in a housing of the drive frame of the movable plate 22.
  • the jack 28 makes it possible to move the movable plate on the fixed plate so as to control, in known manner, the flow of the metal out of the metallurgical container.
  • Fig 4 a sectional view of the embodiment shown in Fig 3, along a perpendicular section plane.
  • This figure shows in particular the detail of the pressure means designated as a whole by the general reference 26. They comprise a helical spring 46, one end of which is supported on the frame 12 and the other on a rocker arm 48. The rocker arm transmits the action of the spring, in opposite direction, on the movable plate.

In its other position it enters a housing 53 provided in the drive frame of the movable plate 22. In the first position it immobilizes the drive frame of the plate fixed relative to the frame and, in its second position, relative to the drive frame of the movable plate.
  • the jack 28 has a sufficient stroke to move the assembly of the two frames sufficiently to release the fixed plate from the grip of the pressure means of the fixed plate against the junction surface of the pouring orifice.
