Definitions

  • the present invention relates to the field of metallurgy, more particularly the adjustment of the composition or the inclusion treatment of a bath of molten metal by the introduction of an additive using a cored wire containing said additive.
  • Metals and metal alloys such as steel or cast iron, have properties that depend in particular on their composition. In the manufacture of metals and metal alloys, one generally starts from a base composition whose content in certain components is adjusted according to the desired final composition.
  • This adjustment is done according to several techniques among which the introduction into the bath of molten metal of a predetermined length of a cored wire, that is to say a longiform element consisting of an outer envelope in which is contained in powder form, the additive which is desired introduction.
  • the envelope of the cored wire is generally made from a metal sheet of small thickness or strip, whose two opposite longitudinal edges are folded so as to hook to each other after having given said sheet a tubular configuration.
  • This cored wire is produced in the form of a coil of great length, for example 6000 meters.
  • Classically as illustrated schematically in figure 1 of the document FR 2.871.477 , it is extracted from the coil which is either static, arranged inside a cage, or dynamic, wound on a drum, then it passes in a horizontal course in an injector, which drives it into a guide tube elbow.
  • the cored wire exits the distal end of the guide tube at a determined height above the surface bath, of the order of 1 to 1.4 meters.
  • the injector shown in figure 1 of the document FR 2.871.477 is a conventional injector comprising three sets of two cylindrical rollers, driven in rotation, between which passes the cored wire.
  • the pressure exerted by rollers must be sufficient to allow extraction of the wire from the coil and driving said wire to the bath, through the guide tube. This pressure generally causes deformation of the wire in cross section.
  • This introduction operation therefore generally has a very low yield, addition yield which can be of the order of 10 to 15%.
  • this second envelope makes it possible to introduce the cored wire to a greater depth and thus to minimize the effects of explosion and / or vaporization of the additive.
  • the document JPS59-162161 U discloses a drive installation of a cored wire.
  • This installation comprises two pairs of rollers for driving the cored wire, these pairs each comprise a drive roller and a driven roller, pressed against the drive roller.
  • one roll comprises a flat wafer and the other comprises a concave wafer, wrapping the wire partially. It is specified that the wire is flattened as to the contact with the flat wafer in order to improve the linearity of the cored wire.
  • the purpose of the applicant is to propose a complementary improvement which is not related to a change in the structure of the cored wire but which takes into account the method and the installation of introduction.
  • This is a method which, in known manner, consists of extracting the cored wire from a coil and driving it in displacement to the metal bath, part of the path of the cored wire being made in a tube of guidance whose distal end is at a predetermined height of the surface of the metal bath.
  • the cored wire is driven and is subjected to a straightening operation, under conditions not substantially altering its substantially circular section and allowing its introduction and penetration into the depth of the bath according to a vertical direction.
  • the straightening operation is carried out by the passage of the cored wire, before entering the guide tube, in several sets of two pressure rollers.
  • the pressure exerted, the number of sets of the pressure rollers, their respective distance, the configuration of the contact with the flux-cored wire are determined so as to obtain the desired straightening, namely that in the free state the flux-cored wire retains a rectilinear configuration and does not tend to resume the curved configuration that it had when stored in the coil, and so that the straightened cored wire keeps its substantially circular section.
  • the contact faces of the rollers with the cored wire are concave.
  • the radius of curvature of the concave faces of the pressure rollers is substantially the same as that of the cored wire.
  • the pressure exerted by the rollers is exerted substantially radially on the cored wire so that there is no crippling crushing or deforming said wire, even with significant pressure.
  • the curvature of the concave faces of the pressure rollers should be strictly the same as that of the cored wire, which would make it possible to have a total homogeneity of the pressure forces exerted radially on said wire over the entire surface of the contact between the wire and the roll, but would require to change the rollers according to the diameter of the wire. Nevertheless, it has been found that the radius of curvature of the concave faces may be slightly different from that of the cored wire without causing crushing or annoying deformation of the wire while preserving the correct straightening of the wire.
  • the cored wire is held laterally during its passage between sets of pressure rollers, in particular by intermediate guide tubes.
  • the purpose of this particular provision is to keep the cored wire so that it remains straight during its course in the set of sets of two pressure rollers.
  • the driving of the cored wire is carried out at the same time as its straightening, in particular when the straightening is obtained by passing between successive sets of rollers, some of these rollers being then rotated.
  • the drive of the cored wire can in particular be performed upstream and regardless of its recovery.
  • the straightening operation is performed under conditions to rectify the cross-section deformation of the wire caused by the drive system. This is preferably obtained with a rectification using rollers having concave faces whose radius of curvature is substantially the same as that of the undeformed cored wire.
  • the guide tube has a vertical direction.
  • the installation comprises means for straightening the cored wire which are arranged before entering the guide tube and able to give the cored wire vertical rectilinear direction without substantially altering its substantially circular section.
  • the rectifying means consist of a plurality of sets of two pressure rollers, the contact of each roller with the cored wire being made according to a contact surface or in two continuous contact lines.
  • the rectifying means consist of a limited number, for example from three to five, sets of pressure rollers whose contact faces with the cored wire are concave; of preferably the concave contact face of each pressure roll has a radius of curvature which is substantially the same as that of the cored wire.
  • each contact face of each roll corresponds to an angular portion of between 120 and 180 °. It is understood that in theory the angular portion of 180 ° provides a radial distribution of pressure forces over the entire outer periphery of a reference wire whose radius corresponds strictly to the radius of curvature of the pressure rollers. The angular portion in the range between 120 ° and 180 °, however, straighten wires of diameter greater than this reference wire without crushing or annoying deformation.
  • the straightening means are constituted by a large number, for example from twelve to twenty, sets of pressure rollers, in which each roll has a peripheral groove of triangular section, delimiting two oblique contact faces. with the cored wire.
  • the installation comprises, between each pair of sets of pressure rollers, an intermediate guide tube capable of holding the wire laterally as it moves between sets of pressure rollers in a rectilinear direction.
  • the ratio between the inner diameter of the guide tube, and possibly interposed tubes, and the diameter of the cored wire is of the order of 1.5 to 5.
  • the guide tube must allow free movement of the cored wire by forcing it nevertheless to maintain a rectilinear vertical direction. This function is fulfilled for the aforementioned range by the same guide tube for the usual range of flux cored wire diameter.
  • the distal end of the guide tube is provided with a protective tip more thermally resistant than said guide tube.
  • the purpose of the implementation of this protective tip is to avoid alteration of the distal end of the guide tube due to the heat of the molten metal bath and also due to projections.
  • the protective tip may extend beyond the distal end of the guide tube over a given distance, for example of the order of 10 to 30 cm.
  • the guide tube is in at least two parts, namely on the one hand, a proximal part and on the other hand, a distal portion equipped with the protective cap, the two said parts being securable by means removable connection, in particular by threading or bayonet system, so as to allow the replacement of the distal portion of the tube and the protective tip.
  • the straightening means of the cored wire act as drive means.
  • each set comprises a driven roller and a free roller.
  • the free roller is mounted on a pivoting arm, forming a rocker, movable cylinder.
  • the rectifying means are dissociated from the drive means, the latter consisting of an injector disposed upstream of the rectifying means.
  • the cored wire necessarily has in the rectifying means, a vertical direction.
  • the rectifying means are able to correct the deformation caused on the wire, in cross section, by the rectifying means.
  • the installation 1 is intended for the introduction of a cored wire 2 into a bath 3 of molten metal in order to adjust the composition of this bath or to treat it with a component or additive, which is contained under powder form inside the cored wire 2.
  • the cored wire 2 has a structure which is in accordance with that described in the document FR 2.871.477 . More specifically, the additive 4, in powder form, is housed inside a first metal sheath 5, which is surrounded by a casing 6 which, itself, is surrounded by a second metal sheath 7 In cross section as shown on the figure 3 , the cored wire 2 has a generally circular configuration, the intermediate casing 6 being sandwiched between the two metal sheaths 5 and 7. Each of the two metal sheaths 5, 7 is made from a strip whose two longitudinal edges opposed are folded so as to hook to each other after the strip has been given a substantially tubular configuration. These attachment zones are schematically represented on the figure 3 under the references 5a and 7a, being turned towards the inside of the tubular wire 2.
  • the intermediate casing 6 is made of a material which is combustible but without leaving troublesome residues in the molten metal bath and which momentarily delays the propagation of heat towards the core of the cored wire 2.
  • this interlayer consists of several strips of paper wound helically around the first metal sheath 5, being a pyrotechnic type paper, having a higher fire resistance and thermal resistance coefficient to those of ordinary paper.
  • the supply of cored wire 2 is made from a platform 8 supporting two coils 9, 9 'in which large and continuous lengths of cored wire 2 are wound, for example of the order of 6000 linear meters.
  • the second coil 9 ' serves as a reserve for the supply of wire at the end of the first coil 9.
  • each coil 9 is held statically inside a cage 10. During the extraction of the cored wire, the coil 9 remains fixed, the cored wire 2 being extracted from the heart of the reel.
  • This mode of presentation of the cored wire 2 has the advantage over a conventional winding on a drum does not require rotation of the coil during unwinding.
  • it has the major disadvantage that can be overcome by the present invention, namely to considerably increase the deformation capacity of the flux-cored wire in the free state, which deformation prevents the rectilinear penetration of said wire into the molten metal bath. .
  • the installation 1 comprises successively on the path of the cored wire 2 a guide assembly 11, a trainer and rectifier assembly 12, a guide tube 13 and a protective cap 14.
  • the guide assembly 11 serves to accompany the cored wire 2 taken from the coil 9 during its transfer to the input of the trainer / rectifier assembly 12.
  • This guide assembly 11 comprises a number of rollers 15 which are rotatably mounted each along an axis These rollers 15 are mounted on a frame 16 having generally an inverted U shape, with two elbows whose ends respectively upstream 16a and downstream 16b have a substantially vertical direction.
  • the cored wire 2 taken from the coil 9 is introduced into the upstream end 11a of the guide assembly 11, it is supported by the rollers 15 and prevented from coming out of the guide assembly 11 because of its configuration. cage form, with hoops 17 fixed to the frame 16 at the level and / or between the rollers 15.

  • the cored wire 2 is wound in the form of substantially joined turns.
  • the wire drawn upward gradually deforms to move from the spiral configuration to a substantially rectilinear configuration due to the traction exerted. Nevertheless, this passage generates internal stresses that cause the wire to keep "in memory” its configuration in the initial turn, a configuration that it finds at least in part when the traction exerted on it ceases. These internal stresses are in addition to those that had been caused during the winding operation.
  • the assembly 12 fulfills both the driving function of the cored wire 2 and the straightening function of said wire.
  • the drive function can be dissociated from the recovery function; in this case, however, it is preferable that the drive assembly is disposed upstream of the recovery assembly and that the path of the wire in the recovery assembly is in a vertical direction relative to the theoretical plane PP 'of the surface of the bath of molten metal 3.
  • the trainer / rectifier assembly 12 which is illustrated in FIG. figure 2 comprises a succession of five sets 18 of two pressure rollers 19,20 between which passes the cored wire 2, in a vertical direction.
  • Each roller 19,20 of each set 18 is in contact with the cored wire 2 according to a contact face 21,22 which is concave.
  • each concave face 21,22 has approximately the same radius of curvature as that of the outer face of the cored wire 2, namely the second metal sheath 7.
  • these rollers 19,20 could nevertheless be used for training and straightening wire 2 having a radius of curvature less than that of the wire shown.
  • each concave face 21, 22 prefferably corresponds to an angular portion ⁇ of between 120 ° and 180 °, for example 130 °, in particular when the driving and straightening operations are independent and the straightening means must be correct the deformation caused on the wire during its passage in the drive means.
  • rollers 19 One of the rollers 19 is rotated, while the other 20 is freely mounted on its axis.
  • This free roller 20 is mounted on a pivoting arm 23 whose pivot axis 28 is offset relative to said free roller 20.
  • This pivoting arm 23 is moved by a jack 24 whose body 25 is pivotally attached to the frame 29 of the assembly 12 and whose rod 27 is pivotally mounted on the arm 23, opposite the axis 28 of said arm 23.
  • the contact faces 21, 22 may have a certain texture, symbolized by the curved lines 29 on the figure 3 , so as to increase the coefficient of friction between said faces 21,22 and the outer face of the cored wire 2, allowing optimization of its transfer and also its recovery.
  • the cored wire 2 takes a vertical direction. To constrain, if necessary, the wire 2 to keep this direction, it is expected, in the assembly 12, intermediate tubes 30 which extend over the entire height of the assembly 12 in the intervals between the five games 18 pressure rollers 19,20 and in the input and output portions of said assembly 12, and in which the flux-cored wire 2 passes.
