Definitions

  • the present invention relates to the technical field of the continuous casting of liquid metal and more particularly to a device for holding and changing the plate of a metal casting installation.
  • the liquid metal is generally contained in a metallurgical vessel, for example a distributor, before being transferred to another container, for example in a casting mold.
  • the metal is transferred from the container to the container by means of a nozzle formed on the bottom of the metallurgical vessel, called the inner nozzle ("inner nozzle” in English), coming into sealing contact with a sliding transfer plate (or casting plate) brought in the extension of the internal nozzle through a holding device and plate change, reported under the metallurgical vessel.
  • This sliding plate makes it possible to transfer the liquid metal, either in the form of a free jet or by guiding the jet when the plate is an external nozzle ("pouring nozzle” or "outer nozzle” in English), comprising a pouring tube.
  • the plate holding and changing device comprises on the one hand clamping means intended to press against the internal nozzle, in particular downwards, for the pressing against the frame of the device, and pushing means, intended to press the sliding plate, in particular upwards, so as to press the plate against the inner nozzle, in order to obtain a sealed contact.
  • the inner nozzle is a stationary member during casting. Therefore, its life should be substantially that of the metallurgical vessel.
  • the sliding plate meanwhile, can be replaced during casting thanks to the device for holding and changing the plate
  • the inner nozzle and the plate each comprise, at least in part, a refractory material.
  • a problem lies in the fact that the forces exerted by the clamping or thrusting means tend to exert stress on the refractory material. These stresses can cause the deterioration of the refractory material, in particular cracks.
  • the invention is intended to provide an internal nozzle whose quality and integrity of the material will be maintained during the life of the nozzle.
  • the invention particularly relates to an internal nozzle for the transfer of liquid metal contained in a metallurgical vessel, the casting direction defining a vertical direction, the inner nozzle comprising an inner nozzle plate comprising a lower contact surface , extending in a substantially horizontal plane called sliding plane, intended to be in sealing contact with a sliding plate slidably brought facing the inner nozzle by a holding and plate changing device, the internal nozzle further comprising a metal casing and at least one so-called bearing surface intended to be in contact with a frame of the device, extending in a substantially horizontal plane, called the support plane, characterized in that the bearing surface is formed on the metal casing of the nozzle and in that the support plane is set back vertically relative to the sliding plane of the nozzle.
  • the nozzle is less sensitive to stress, resulting in fewer cracks, less air suction, less risk of metal infiltration, less wear of the nozzle and an improvement in the quality of the metal. sank.
  • the support plane is sufficiently recessed relative to the sliding plane so that the wear of the lower contact surface, made of refractory material, does not interfere with the setting of the internal nozzle in the frame .
  • the envelope is metallic but all the other materials making it possible to fulfill the same function could be envisaged.
  • the metal casing is thick and has walls having a thickness greater than 6 mm. This facilitates the flowability of the envelope, for example cast iron, during manufacture. Thus, relatively complex envelope shapes can be obtained while keeping acceptable manufacturing costs.
  • the bearing surface presented above made of metal, has a sufficient area for the inner nozzle can bear on the frame.
  • the bearing surface is distinguished from a simple peripheral wall of a traditional metal shell, whose thickness rarely exceeds 2 or 3 mm (millimeters). Such a dimension is not sufficient to serve as a support surface.
  • clamping system means a clamping system of the inner nozzle, for exerting pressure on the inner nozzle to immobilize it with respect to the frame on which is mounted the clamping system.
  • the force exerted by the clamping system on the inner nozzle is a force directed in particular downwards, applied to an upper surface of the inner nozzle.
  • the vertical direction is further defined as the direction of flow of the liquid metal at the outlet of the metallurgical vessel, the longitudinal direction as the direction of plate change of the device, and the transverse direction as the direction perpendicular to the other two directions vertical and longitudinally, so that the longitudinal, transverse and vertical directions define an orthogonal reference.
  • the forward direction is defined with reference to the direction of plate change in the plate changing device, the plate being moved from the rear to the front to take the following successive positions: waiting position (when another plate is already in the pouring position), casting position (when a pouring orifice formed on the plate extends the pouring channel of the internal nozzle), position shutter (when a sealing surface formed on the plate closes the pouring channel) and ejection position (when the sliding face of the plate is disengaged from the pouring channel).
  • the inner nozzle and / or the sliding plate are generally each composed of a metal casing surrounding a refractory element, and that the sliding plate may optionally be an external nozzle, comprising a pouring tube made of refractory element.
  • the inner nozzle may further include one or more of the following features, taken alone or in combination.
  • the bearing surface projects from a peripheral surface of the inner nozzle plate.
  • Peripheral surface means the surface extending from the periphery of the lower contact surface of the plate, preferably in a substantially vertical direction.
  • the bearing surface has a length and a width, each having a dimension greater than 5 mm, preferably equal to or greater than 10 mm.
  • the surface has an area large enough for the nozzle to bear on the frame.
  • the nozzle comprises at least two separate bearing surfaces.
  • "Separate surfaces” means separate, non-contiguous surfaces. They may for example be separated from each other by an empty space or by a rib.
  • the nozzle comprises three distinct bearing surfaces, and only three. These bearing surfaces make it possible to provide satisfactory support at three distinct points while optimizing the space available around the nozzle and in the device for holding and changing the plate, this space being more free than when the nozzle has four or more bearing surfaces.
  • the nozzle comprises a vertical central longitudinal plane and the three bearing surfaces are arranged in a Y on the periphery of the metal casing, the base of the Y being disposed in said longitudinal plane and the two branches of the Y being disposed on both sides. other of this plan.
  • the two branches of Y are symmetrical with respect to the central plane.
  • the plane corresponds to a central vertical longitudinal plane, that is to say that it extends in the longitudinal and vertical directions of the nozzle and that it passes through the center of the nozzle, this center can be defined by the center of the casting orifice of the inner nozzle.
  • the center of the inner nozzle corresponds to the center of the casting orifice of the inner nozzle.
  • the center of the inner nozzle corresponds to the center of the contact surface of the nozzle, for example the center of the rectangle circumscribed to the contact surface of the nozzle.
  • the metal shell has four contiguous edges, namely two longitudinal edges and two transverse edges, the longitudinal direction being defined by the direction of plate change in the device, the bearing surface or surfaces being provided only on the transverse edges of the envelope.
  • the bearing surfaces thus positioned in the transverse direction make it possible to reference the inner nozzle with respect to the holding and plate changing device along the transverse direction, which is particularly interesting.
  • the internal nozzle undergoes a number of tensions in the longitudinal direction during the plate changes, so that the clamoring forces distributed in the transverse direction, which allow to press the nozzle against the frame, can wedge the internal nozzle in the longitudinal direction, and thus to immobilize it in the longitudinal direction despite the movements due to plate changes.
  • the inventors have found that it is more advantageous to exert forces in this way than when the thrust force and the clamping force are applied opposite each other, as is practiced in the state of the art, because the strong pressure on the longitudinal edges of the inner nozzle and the sliding plate can generate a spacing of the respective transverse edges.
  • the nozzle comprises at least one wedging flange of the inner nozzle against a frame provided on the holding device and the plate changing device, the calibration flange comprising
  • a so-called clamming surface on which a clamping system is intended to apply a clamping force arranged opposite the bearing surface, this clamping surface being formed on the metal casing of the nozzle.
  • the chock flange is made entirely of metal.
  • the metal rim is solid, that is to say that there is only metal between the bearing surface and the clamming surface, so that only metal is put under stress during clamping, which spares the refractory material of the internal nozzle.
  • the metal surfaces of the flange may be separated by a non-metallic material such as refractory.
  • the wedging flange of the nozzle is sandwiched between the frame and the clamping system.
  • the bearing surfaces or the clamping surfaces are flat. Alternatively, the surfaces may have different shapes, for example, inclined, curved or grooved.
  • the bearing surfaces or the clamping surfaces extend in a substantially horizontal plane. Of preferably, the bearing surfaces or clamage are in a substantially horizontal plane. It is important that the surfaces can fulfill their roles as support surfaces or as clamping surfaces.
  • an element such as fiber, a seal or a compressible element could be associated (added, glued or juxtaposed) to the support or clamming surface. The advantages of the present invention are retained.
  • the invention also relates to a metal casing for an inner nozzle as described above, and a method of assembling a metal casing and a refractory element to manufacture such an inner nozzle.
  • the invention furthermore relates to a set of an internal nozzle and a device for holding and changing a sliding plate for the transfer of liquid metal contained in a metallurgical vessel, the internal nozzle comprising a metal casing, the device comprising
