Definitions

  • the subject of the invention is a method and a machine for the continuous casting of thin metallic products in the form of strips, in particular of steel.
  • the process normally used consists in casting the steel in a mold in the form of a bottomless mold with cooled walls limiting an internal tubular space in which the product is formed, the latter consisting of a liquid core surrounded by an envelope consisting of solidified surface skin.
  • This product is continuously discharged through an orifice placed at the outlet of the ingot mold, the latter generally having a vertical axis, and the product then passes through a secondary cooling device in which the solidification of the product is completed and which comprises domc holding means and means for cooling the solidified faces of the product, the assembly being placed inside a frame which forms a sort of tubular corset surrounding the product until the solidification is completed.
  • the metal, brought in the molten state into a ladle is poured into an intermediate container which makes it possible to ensure the continuity of the ladle during the replacement of the ladle and which is itself provided with a tap hole, the flow rate of which is conventionally regulated by a nozzle and by which the metal is poured inside the ingot mold.
  • an immersion nozzle is used comprising a pouring tube which penetrates inside the ingot mold and plunges into the bath to protect the liquid steel from oxidation and to direct its flow in the ingot mold.
  • the internal tubular space of the mold has a rectangular shape limited by two wide walls and two narrow walls corresponding respectively to the large and the short sides of the product.
  • the minimum width of industrially cast slab is of the order of 150 mm.
  • French patent 1,505,630 also provides a mold in the form of a hopper but whose wide walls converging downward are composed of cylindrical envelope sectors allowing a circular oscillation movement. Such an arrangement is difficult to implement and supposes, like the previous one, that the product is. completely formed at the outlet of the mold. This results in a risk of blockage by wedge effect with tensile forces exerted in a particularly sensitive zone of the installation.
  • the subject of the invention is a new process and a machine making it possible to produce thin products while retaining the advantages of conventional machines, that is to say, generally, the formation of the solidified crust in an ingot mold with cylindrical walls with generatrix parallel to the casting axis, and maintaining a core of molten metal inside the product at the outlet of the mold, complete solidification being carried out in a secondary cooling device comprising means for cooling and maintaining at least the large faces of the product until complete solidification.
  • the latter comprises as in the arrangements described above, an enlarged central part narrowing towards the sides to a thickness equal to that of the thin color product.
  • This section is kept up to the exit of the mold, the latter having wide cylindrical walls with generatrix parallel to the axis of casting and oscillations.
  • the wide walls of the mold are given a curved shape so that the cast product has an enlarged central part which narrows in the form of spindle up to edges having a thickness equal to that of the thin product to be cast and then a gradual flattening of the central part of the product is carried out up to a thickness equal to that of the edges in a reduction cage placed immediately after the outlet opening of the mold and comprising two guide and straightening surfaces, respectively, of the two large faces of the product, the profile of which is determined as a function of the casting speed so as to exert a pressure uniformly distributed over the entire surface causing and controlling on each of the large faces the symmetrical displacements of two straightening zones from the edge towards the axis at a speed whose axial and radial components are synchronized with the casting speed so as to achieve a continuous straightening of the longitudinal walls of the product until complete solidification.
  • an ingot mold is given an internal profile such that the large longitudinal faces of the product end at the edges by plane end portions parallel to the longitudinal plane of symmetry of the ingot mold and perpendicularly cutting the small faces of the product and, in the thickness reduction cage, a straightening of the central part is carried out by allowing a gradual widening of the flat end parts, these being kept perpendicular to the small faces.
  • the profile of the support surfaces of the large longitudinal faces of the product is determined as a function of the casting speed and the cooling conditions, so that each straightening zone moves towards the axis at a speed substantially constant radial and coordinated with the casting speed and with the thickening speed of the solidified skin so that the complete solidification and straightening of the large faces of the product are carried out substantially at the same time at the outlet of said reduction cage .
  • the invention also covers a machine for continuously casting thin products for implementing the method, comprising an ingot mold having at its upper part, in cross section, a sufficient thickness in its central part for the introduction of the pouring tube ( T) and narrowing towards the two sides to a thickness of the order of that of the product to be poured, and a secondary cooling device comprising means for holding, with cooling, the large faces of the product poured until solidification complete.
  • the shape, in cross section, of the internal tubular space (13) of the ingot mold (1) is preserved until it exits so that the product leaving through the lower orifice (16) of the mold (1) has a part (55) thicker than the edges (57) and the secondary cooling device comprises a thickness reduction cage placed immediately below the mold and provided with means holding defining two substantially continuous surfaces for guiding the large faces of the product and limiting an internal space for the passage of the product having on its sides a constant thickness equal to that of the sides of the mold and in its central part, a thickness gradually decreasing in the direction of casting between an inlet of cross section identical to that of the outlet of the mold and an outlet of rectangular section corresponding to that of the min product this to color.
  • the strip product is left free to widen towards the sides depending on the flatness of the central part, so that the perimeter, in cross section at the axis, remains preserved.
  • the two wide walls of the mold and the two guide surfaces defined by the means for holding the large faces of the product in the thickness reduction cage comprise a central curved part of concave shape towards the interior, extended laterally by two convex tangential connection parts, on one side to the concave central part and on the other, to an extreme flat part parallel to the longitudinal plane of symmetry of the mold and perpendicularly cutting the narrow walls of the ingot mold and the small faces of the product, said concave central parts and of convex connection progressively straightening in the thickness reduction cage, so as to be aligned with the flat end portions at the outlet of said thickness reduction cage.
  • the means for holding the product in the thickness reduction cage carry out continuous and frictionless support of the large faces of the product, by forming along said faces a film of support fluid under pressure. at least equal to the ferro-static pressure in the product.
  • the thickness reduction cage is limited by two longitudinal walls each consisting of a plurality of adjoining boxes, for injecting fluids under pressure, distributed so that their edges are aligned in two perpendicular directions and form a product holding grid on each wall.
  • the support grid consists of longitudinal and transverse bars placed in directions respectively parallel and perpendicular to the pouring axis, the longitudinal bars facing each other forming two by two, in the central part, a V open upwards which gradually closes going towards the sides, the extreme longitudinal bars being parallel and spaced apart by a distance substantially equal to the thickness of the product to be formed, and the transverse bars of the same grid forming at the entry of the cage an obtuse angle which opens in the direction of casting until it becomes a flat angle at the exit of the cage.
  • the means for holding the product, in the thickness reduction cage consist, for each large face, of at least one series of rollers with parallel axes whose spacing and diameter are determined as a function of the thickness of the skin solidified at this location, and of the deformation effort of the product.
  • Said rollers are limited by an external surface of revolution generated by an enveloping line, in the plane passing through the axis of the roller and perpendicular to the casting axis, the cross section to be given to the internal space of the cage.
  • FIG. 1 there is a diagrammatic representation of the upper part of a continuous casting installation represented in section by the median plane P2 perpendicular to the longitudinal walls and passing through the casting axis 10.
  • the installation comprises an ingot mold 1 constituting a bottomless mold opening into a secondary cooling device comprising, in a conventional manner, a first cage 2 placed immediately at the outlet of the ingot mold 1 and a cooling and guiding corset 3 in which the solidification ends.
  • the ingot mold 1 is made up, in the usual way, of two wide walls 11 and two narrow walls 12 respectively forming the large and small sides of an internal tubular space 13 symmetrical with respect to the two median planes, longitudinal P1 and transverse P2 and mounted inside a frame 14, itself fixed on a table 15 which is connected to a casting floor 20 by means of guidance and oscillation, not shown well known in the art and which allow to animate the mold for oscillating movements along the casting axis 10.
  • the two wide walls 11 have a cylindrical profile with generatrix parallel to the axis and curved in cross section so as to limit an internal tubular space 13 in the form of a spindle symmetrical with respect to two planes, respectively longitudinal P1 and transverse P2 passing through the axis 10 and comprising a convex central part 17 tapering progressively, in the direction transverse to the axis, towards two short sides 18 limited by the two narrow walls 12 interposed, conventionally, between the two wide walls 11, and having a narrow width (1), substantially equal to the thickness of the strip product to be formed.
  • the longitudinal walls 11 of the mold include a central part 17 convex inwards and connecting, by two median parts 19, to two flat lateral parts 18 parallel to the plane longitudinal symmetry P1.
  • the product leaving the ingot mold through the lower orifice 16 has a central portion 55 thicker than the edges 57.
  • the product 5 immediately passes into the first part 2 of the secondary cooling device, the latter being, conventionally, constituted by a cage provided with means for holding the large faces of the product, the constitution of which is adapted to the small thickness of the skin solidified at this location.
  • the means for holding the two large faces of the product consist of two grid-shaped walls 4 comprising longitudinal bars 41 placed in planes parallel to the median plane and transverse bars 42 orthogonal to the axis 10.
  • the longitudinal bars 41 placed opposite one another in the same vertical plane form two by two in the central part, a V open upwards at an angle A which gradually closes when one approaches the sides of such so that the extreme longitudinal bars 410 are parallel and spaced apart by a distance 1 corresponding to the thickness of the strip leaving the ingot mold.
  • the transverse bars 42 the shape of which is adapted to that of the product, form, at the inlet 43 of the holding cage 2, an open curve of an obtuse angle B and the radius of curvature of which gradually increases when 'we are going down in the direction of casting, the lower bars 420 placed at the outlet of the cage being practically rectilinear.
  • the two wide walls 4 limit an internal space 40 for the passage of the product having on the sides 48 a constant thickness (1) equal to that of the sides of the mold and, in its central part 47, a thickness which gradually decreases in the direction of casting, between the inlet orifice 48 of the holding cage 2, of section identical to that of the outlet orifice 16 of the ingot mold and an outlet orifice 44 placed at the bottom of the cage 2 and having a rectangular section corresponding to that of the thin product to be formed.
  • This reduction in thickness is possible because the cast product consists, at the outlet of the ingot mold, of a liquid core 51 surrounded by a solidified skin 52 and therefore deformable.
  • the grid for holding the longitudinal faces of the product in the thickness reduction cage constitutes a practically continuous bearing surface and as much as possible, without friction.
  • the holding surfaces of the two large faces of the product in the thickness reduction cage are each constituted by a plurality of adjoining boxes which can be delimited by the longitudinal bars 41 and transverse bars 42, or else made as shown in Figs. 6 and 7.
  • Each box is closed towards the outside by a bottom 61 and on the sides by edges 62, limiting, on the product side, a wide opening orifice 63 into which opens a conduit 64 connected to a circuit not shown pressurized fluid supply.
  • the fluid pressure is determined according to the location of the box, that is to say the height of liquid steel there and the shape and thickness of the solidified wall, so as to balance the ferro-static pressure at this level, with a leakage rate along the edges 62 making it possible to provide a width space (3) between the product and the grid to avoid contact (Fig. 4).
  • the boxes are arranged in successive stages 65 (Fig. 6) whose height is determined on the one hand, so as not to excessively multiply the number of stages and on the other hand, so that the ferro-static pressure on the height of the box is relatively constant.
  • each stage 65 may comprise a single box extending over the entire width of the product and preferably supplied by several nozzles 66 for injecting fluid connected to a single supply channel 64.
  • edges 62 of the boxes are preferably aligned in longitudinal and transverse directions, constituting a product support grid and that is why it is also possible to limit the boxes, as in the embodiment of FIG. 3, by longitudinal bars 41 and transverse bars 42.
  • the profile of the holding surfaces of the large faces of the product is determined as a function of the casting speed and of the cooling conditions, so as to ensure a gradual recovery of said large faces, as and when measure of their thickening and therefore their hardening.
  • each longitudinal face of the product comprises a central part 55 convex towards the outside extended by two concave parts 56 of tangential connection, on one side to the central part 55 and on the other, to a flat end portion 57 parallel to the longitudinal plane of symmetry P1 and cutting perpendicularly and preferably at sharp angles to the small face 54 of the product.
  • Each product support surface 4 5 therefore comprises, at the upper part of the straightening cage 2, a central part 47 concave towards the axis 10, connecting by convex median parts 49 to lateral parts 48 parallel to the longitudinal plane of symmetry P1.
  • Figs. 4 and 5 the recovery process is shown schematically.
  • Fig. 5 shows, in perspective, the evolution inside the thickness reduction cage (not shown) of the product 5 comprising a liquid metal core 51 surrounded by a solidified skin 52 whose thickness increases in the direction of progression of the product, that is to say in the oz direction, the figure being related to an Oxyz trihedron.
  • the planar extreme part 57 which goes from the angle A to the point B1 must have a width (D) such that the righting force of the face 53 does not make the solidified product undergo any effect on the edge A.
  • a thrust is distributed continuously over the two curved parts 55 and 56, so that the width d of the flat portion 57 increases continuously as the product advances and the thickening of the solidified skin 52.
  • the tangent plane P to the large face 53 at point c1 makes an angle U with the axis Ox and an angle V with the axis Oz and these two angles close progressively from point c1 to point c2, during the progression of the product and of the straightening of the face 53.
  • the profile of the wide walls 4 of the straightening cage is determined so that the speed dy / dt of transverse displacement of the point c1 and the speeds of rotation dU / dt and dV / dt of the tangent plane P respectively in the horizontal and vertical directions, are compatible with the casting speed dzldt, of the product and sufficiently weak so that the resulting elongations between points c1 and c2 do not create any defect in the solidified skin, taking into account zon thickness and quality of the metal.
  • the current knowledge of a technician specialized in continuous casting which is based on several years of operation of casting machines, makes it possible to define with a certain precision, the resistance to deformation of the solidified skin 52.
  • this skin retains, until complete solidification, sufficient flexibility to allow the progressive straightening which takes place by means of a thrust uniformly distributed with pivoting of the solidified wall around the connection zone 58 with the flat part 57 which constitutes a fulcrum for the righting effort, since solidification progresses more quickly on the lateral edges of the liquid core 51.
  • the fluid used is not a cooling agent or at least is the least possible, which leads to choosing air or a neutral gas, preferably water.
  • the perimeter of the product in cross section is kept during its descent and its flattening in the holding cage 2.
  • the latter does not will therefore include, as indicated in FIG. 3, only wide walls 4 so as to allow the product to widen slightly on the sides. Due to the small width of the product on its sides, this absence of retaining walls of the small faces 54 has no disadvantage, the solidified skin being sufficiently thick at the outlet of the mold.
  • the profile of the support faces 4 being determined so that the liquid core 51 remains practically up to the outlet orifice 44 of the straightening cage, there is therefore no need to fear that the product will be blocked at this point by corner effect.
  • the lower part 3 of the secondary cooling device placed below the straightening cage 2 can consist, quite conventionally, of a series of rollers 31. All the conventional arrangements can moreover be used in this part and it should be noted that the thin thickness of the product formed 53 makes it possible to direct it horizontally more quickly than in relatively thick slab casting installations.
  • the second part 3 of the secondary cooling device can therefore be shortened, or even in certain cases, eliminated and, even if the first cage 2 has to be lengthened, the total height of the installation should ultimately be reduced.
  • the width (L) of the central part of the internal space 13 is determined so as to allow the introduction into the ingot mold of the pouring tube T extending the outlet nozzle of the intermediate container. In this way, it is possible to carry out the casting in a completely conventional manner with, in particular a regulation of the flow of liquid steel and the level of the latter inside the mold.
  • the wide walls 4 of the reduction cage 2 are each mounted on a support frame 21 provided at its upper part with suspension ears 45 articulated around horizontal axes on a fixed frame 22 or directly on the casting floor 20.
  • two identical cylinders 23 placed on either side of the cage and fed and / or controlled simultaneously are articulated at their two ends, respectively on the two chassis 21 for supporting the walls 4.
  • the double-acting cylinders 23 it is possible to control the opening or tightening of the support walls 4. It is thus possible to quickly open the reduction cage 2 by example to clear the product in case of breakthrough or blockage for any reason.
  • the two chassis 21 for supporting the walls 4 can be articulated one on the other or, as shown in the figure, be provided at their lower part with rollers 25 which bear directly on the strip 53 at the exit of the support cage 2.
  • the retaining and deformation elements constituting the wide wall 4 must provide a practically continuous support for the product around the entire periphery of its large faces and it is desirable, as described above, to produce the wall 4 in the form of a grid.
  • the qualities of the metal give the solidified skin sufficient resistance, it would not be excluded, as shown in FIGS. 8 and 9, to carry out the support of the large faces and their straightening, by means of rollers 7 with horizontal axes or in any case orthogonal to the axis 10 of casting, the centers and the diameters of the rollers being determined as a function of l thickness of the solidified skin and the height of liquid metal at the corresponding level to ensure the maintenance of the wall without risk of tearing.
  • each roller must then be determined so as to correspond, at each level, to the shape of the product and therefore, the latter preferably having a spindle shape, the outer surface of the roller will be constituted by a surface of revolution generated by an enveloping line, in the plane passing through the axis of the roll perpendicular to the casting axis 10, the cross section to be given to the product so that all of the rollers define a retaining and straightening wall of desired shape.
  • the profile of the rollers will depend on their level inside the straightening cage 2 and it may be necessary, taking into account the width of the product, to have an intermediate support in the median plane of the product so that each roller extends only over half the width of the product.
  • the members for holding the large faces of the product consist, on each face, of a series of bars 8 extending over the entire height of the holding cage 2 and slightly spaced from one another.
  • Each bar has, on its face turned towards the product, a profile determined as a function of its distance from the median plane passing through the casting axis 10 so as to pass, as previously, from an inlet orifice 43 of section identical to that of the outlet orifice 16 of the mold with an outlet orifice 44 of rectangular section corresponding to that of the product to be formed.
  • each bar 8 is associated with a pair of cams mounted respectively on two rotation shafts 82 and placed at two levels, respectively upper and lower of the holding cage 2.
  • One of the two cams for example the cam upper 80, engages in a housing 83 formed at the upper part of the bar 8 and comprising a vertical face 84 and two horizontal faces 85, respectively upper and lower.
  • one of the horizontal faces 85 is provided with a pad 25 applied by a spring against the corresponding cam 80.
  • the latter preferably has a circular profile so as to bear, at any time, simultaneously on the three faces and is eccentric with respect to its shaft 82 to determine a movement periodic comprising a horizontal displacement of the bar inwards until contact with the product, a downward movement at the speed of the product while remaining in contact with the latter, a horizontal displacement of spacing and an upward movement which brings the bar in high position away from the product.
  • Fig. 11 which is a detail view in section along the line VV of FIG. 10, and on which only a few bars 8 have been shown, it can be seen that, at the same instant, certain bars 8 are in contact with the product while the alternating bars 86 are moved away from it. In this way, if the width and spacing of the bars 8 are determined correctly, it is possible to maintain large faces of the product by arranging so that they are supported at all times on bars 8 in sufficient number.
