Definitions

  • the present invention relates to the technical field of continuous casting of liquid metal. It relates more specifically to the clamming of an internal nozzle in a continuous 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 may be a calibrated plate, a pouring tube or a cassette comprising two or more plates.
  • the 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 pouring submerged 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, and pushing means, intended to press the sliding plate, in particular upwards, so as to press the inner nozzle and the plate against each other.
  • clamping and thrusting means are arranged along the longitudinal edges of the inner nozzle and the sliding plate, the longitudinal direction corresponding to the direction of plate change.
  • the invention particularly aims to increase the contact between the plate of the inner nozzle and the sliding plate.
  • the invention also aims to optimize the distribution of stresses in the refractory elements.
  • 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 clamping means thus positioned in the transverse direction can further ensure a referencing of the inner nozzle relative to the holding device and plate change along the transverse direction, which is particularly interesting.
  • the internal nozzle undergoes a certain number of tensions in the longitudinal direction during the plate changes, so that the clamping forces distributed in the transverse direction can wedge the inner nozzle in the longitudinal direction, and thus the immobilize in the longitudinal direction despite the movements due to plate changes.
  • clamping means means clamping means of the inner nozzle, for exerting pressure on the inner nozzle to immobilize it relative to the frame on which are mounted the means of clamping.
  • the force exerted by the clamping means on the inner nozzle is a force directed in particular downwards, applied on an upper surface of the inner nozzle, and the force exerted by the thrust means on the sliding plate is a directed force. especially upwards, applied to a lower surface of the plate.
  • the vertical direction is defined as the direction of flow of the liquid metal at the outlet of the metallurgical vessel.
  • the transverse direction is defined as the direction perpendicular to the other two vertical and longitudinal directions, so that the longitudinal, transverse and vertical directions define an orthogonal reference.
  • the forward direction is defined with reference to the direction of change of plate 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 casting position), casting position (when a casting orifice on the plate extends the inner nozzle casting channel), shutter position (when a sealing surface formed on the plate closes the casting channel) and ejection position (when the sliding face of the plate is clear of the container).
  • the inner nozzle and / or the sliding plate are generally each composed of a metal casing surrounding a refractory element.
  • the sliding plate may optionally comprise a tubular extension. This tubular extension may extend sufficiently so that the end thereof is immersed in the metallurgical vessel downstream, for example the casting mold. We will speak, in this case of external nozzle.

  • the rod 66 abuts against the vertical wall of the flange 30a, which has the effect of compressing the spring 68 as illustrated in FIG. figure 5c then 5d. Thanks to this compression of the spring, the system can return to the rest position by simply rotating the cam member 56a. Indeed, when the element 50a is in the position of clamping, as illustrated on the figure 5d , the rotation of the member 56a allows the cylinder 58 to translate in the direction indicated by the arrow 72 under the action of the spring 68 which relaxes, and thus allows the clamping member to resume the position illustrated on the figure 5a .
  • the device 10 further comprises, between the two clamping elements 50b, 50c, two gas injection channels for the nozzle 12, opening onto a vertical transverse surface 51 of the device 10.
  • the injection channels of the device 10 are in the extension of the channels 48 of the nozzle 12, and the clamping position of the elements 50b, 50c ensures a particularly tight connection of these channels.
  • the clamping method comprises a first step of abutment of the transverse vertical surface 49 of the nozzle 12, arranged between the clamping flanges. 30b, 30c, against the transverse vertical surface 51 of the frame 31 of the device 10, followed by an actuation of the first clamping element 50a in the clamping position.
  • the first element 50a translates in accordance with the arrow 70 of the figure 5a , abuts against the flange 30a, which has the effect of pressing the inner nozzle 12 against the transverse edge 51 of the device before the device 10, so refer to it very precisely against this front edge.
  • the setting of the clamping position by the clamping element 50a simultaneously generates the compression of seals arranged in the gas injection channels 48.
  • the seals can be placed on the inner nozzle or on the device. They are preferably made of graphite.
  • the translation along the arrow 70 allows a controlled compression of the joints.
  • the clamping means exert their force on the transverse edges 42a, 42b of the inner nozzle, while the thrust means 18 exert their force on the longitudinal edges of the sliding plate, at the longitudinal edges 17a, 17b of the device 10. It comes out that pressure is exerted on substantially the entire circumference of the contact surface between the inner nozzle 12 and the sliding plate, resulting in a better seal.
