Definitions
- the invention relates to continuous casting in charge of metals, in particular steel. More specifically, it relates to the casting of metals into format semi-finished products. elongated, such as slabs, thin slabs, etc., which are consequently poured into so-called "wide section" molds.
- This tubular element conventionally made of copper, or more generally of copper alloy, has a height ordinary of the order of a meter.
- This tubular element differs from other types of casting mold basically continues by the fact that it is not monolithic, but made up of four plates assembled at right angles: a pair of large plates, facing each other and intended to form the large faces of the poured slab, often much greater than a meter in width, and a pair of small side plates mounted to the right of the ends of the large plates to seal against the molten molten metal.
- these plates are called large or small "walls", or, by analogy with slab casting, large and small "faces”.
- the first solidification proceeds from a very sensitive physical mechanism, in at the same time that it represents an essential factor in the quality of the product obtained. Thanks to the distance in height of these two levels, which are confused, or almost confused in classic continuous casting, this solidification takes place in a hydrodynamically calm place, far from the always disturbed area that is the meniscus region. Concretely, this separation of the two levels is achieved by overcoming the cooled copper body of the ingot mold by an attached extension, not necessarily cooled, made of refractory material high heat insulating properties, well aligned internally with the mold and within which the color will maintain, during the entire duration of the casting operation, the meniscus cast steel, poured from a distributor located just above.
- This spacer should be both good enough heat insulator to maintain in the liquid state, the molten steel that it will contain, like the enhancer, and present good mechanical resistance properties to preserve as long as possible the geometry of the upper edge of the copper wall on which it rests, precisely where will begin the solidification of the cast metal.
- a material like SiAlON (R) responds fairly well to such opposing requirements.
- this type of material is expensive, in especially when it comes to conforming it into a ring hugging the inner periphery of the mold. Its price can even become prohibitive for very long inserts, such as this is necessarily the case for large section molds.
- the aim of the present invention is to provide a simple, reliable and economical answer. to the aforementioned difficulties encountered with continuous casting in charge of wide products section.
- the invention relates to an ingot mold with a wide section for continuous casting.
- vertical in charge of metals, steel in particular comprising a tubular body formed by assembling copper or copper alloy plates, cooled by circulation of a coolant, this cooled metallic tubular body being surmounted by a extension in heat-insulating refractory material aligned internally with it, and having, among the plates which constitute it, large plates each fixed on counter-plates of rigidity with the aid of distributed transverse tie rods, characterized in that the upper part of each of said large plates has a shoulder set back from the plane of the large plate to offer grip to the jaw of an elongated clamp, which fixes thus the upper part of the large plate against the associated counter plate by covering this last from above and ensuring a continuous grip distributed over the width of the large plate, the base of the refractory riser coming to rest on the part of the shoulder left free by the jaw of the stirrup, the other jaw of the stirrup being provided with means for adjusting the clamping by pressing against the associated counter
- the tie rods at the top of the mold are replaced by a clamping bracket whose jaw, and therefore the bearing surface, can also be extended as desired along the upper edge of the large plates, or even continuous, in order to completely counteract the distortion of the upper edge of large copper plates, very sensitive place of the ingot mold for successful laden casting, as explained above.
- This stirrup covers each large plate from above and its associated counterplate. A recess set back from the upper edge of the large plate is thus provided to allow the jaw of the stirrup to take position in the shoulder thus formed on the top of the mold to press the heel of the copper plate and tighten it thereby rigidly against the base plate, on which the other jaw of the stirrup acts.
- the step being voluntarily larger than the bit of the stirrup it receives, the space thus left free on the shoulder in front of the jaw constitutes a centering housing for easy installation of a refractory riser.
- the hard refractory insert can therefore be made much more easily than hitherto "SiAION" provided at the base of the riser.
- This realization by assembling sections juxtaposed (FR-A-2764533) whose alignment with each other guarantees the necessary straightness of the whole assembly is executed, in accordance with a secondary object of the invention, from sections of refractory material each of which is taken hot in a metal shell which provides them with the desired mechanical resistance and which is mounted by thread on a rigid guide rod up to the desired length (equal to maximum to the width of the large plate), and at the ends of which are provided elastic clamping means in order to keep the sections clamped together.
- FIG. 1 it can be seen that the head of a Continuous Casting machine in Vertical load of steel slabs present, in a known manner and in the direction of extraction of the cast metal given by arrow F placed on the casting axis A (i.e. from top to bottom in the figure), a distributor 1 containing a bath of molten metal 2, which it distributes to a (or usually several) ingot mold 3 placed at a distance below by means of a nozzle submerged 4 by ingot mold and whose lateral outlet openings 5 of the metal open out to a ten cm below the free surface 6 of the liquid metal present in the mold.
- This is schematically composed of two superimposed stages 7 and 8 having respective functions distinct but complementary.
- the lower stage 7 constitutes the main part of the mold, the crystallizer, of which the thermally active element 9 has the primary role of giving the cast metal a format with sufficient mechanical strength of the skin to avoid breakthroughs downstream.
- This element 9 a copper tube or more generally a copper alloy, is vigorously cooled by a water circulation in longitudinal channels 10 (shown in the background in the figure) hollowed out on its external face 11, and defines by its very smooth internal surface an internal passage 12 for cast metal.
- the upper stage 8 is formed by an extension 13 of uncooled refractory material, whose inner wall is aligned with that of element 9 of the crystallizer.
- the assembly "cooled metal tube 9 surmounted by the 8 "insulating refractory riser defines a calibrating passage for the cast metal, the portion of which upper within the riser constitutes a buffer zone for containment of disturbances hydrodynamics caused by the arrival of molten metal in the mold through the louvers 5 of the nozzle 4, and the portion which extends it downwards, is an area of solidification of the cast metal.
- This solidification is initiated from the first contact of the cast steel with the cold metal wall of the crystallizer 7, namely already on the upper edge 15 of the copper element 9, and continues downstream, forming a solid crust 13 whose thickness gradually increases from the periphery towards the center as the poured product descends in the mold.
- the crust 13 one to two centimeters thick, is strong enough to withstand the ferrostatic pressure of the still liquid core. She then continues its centripetal growth until total solidification of the product poured under the effect water spray bars, not shown, located in the lower half of the machine.
- the product obtained is cut into sections of desired length (the slabs) and these slabs are then available for further shaping (rolling, etc.)
- the tubular element 9 is conventionally made up of four plates (or walls) assembled at right angles: two large plates facing each other (of which only one, 14, is shown in the figure) and two small end plates, not visible in the figure, intended to close laterally so waterproof the casting space 12.
- These copper plates have a useful thickness of the order of centimeter in order to extract from the cast metal the high heat flux necessary for the solidification process. However, this is insufficient to safely provide resistance mechanical required, facing ferrostatic pressure and multiple constraints and efforts to which the assembled element 9 is subjected.
- each large plate 14 is coupled to a thick steel counter plate 16 to which it is rigidly fixed. Conventionally, this fixing is achieved by tie rods 17 whose free end is screwed into inserts 15 embedded in counterbores provided for this purpose in the longitudinal ribs of large plates 14 delimiting the water circulation channels 10.
- the tie rods 17 normally located at the top of the bottom plate 16 have been replaced in their fixing function by a clamping bracket 22.
- This bracket comes to cover the plate from above bottom 16 and the large copper face 9 paired and whose shape has been modified at this location to be able to offer grip easily to the caliper bit.
- the change of form, as regards the copper plate 9, consists, as can be seen, of a swaying of the upper part of so as to produce a shoulder 23 set back from the plane of the copper plate 9 for offer a grip on the passive jaw 24 of the stirrup 22 on the one hand, and on the other hand to offer a base 25 on which the refractory riser 8 rests.
- the modification of form is more banal: on the "hot” side (towards the inside of the mold), it has a counterbore 26 cooperating with the shoulder 23 of the copper plate 9, on the other side, it includes a shrinkage shrinkage 27 in order to be able to engage in the clamping bracket 22 in providing a support surface for the active jaw 28.
- this jaw 28 is qualified as active since it is provided with clamping means. easily accessible located on the "cold" side of the mold and made up, in the example considered, by a screw 29 engaged in a threaded barrel 30 passing through the jaw 28, the end free of the screw bearing on the bottom plate 16 to ensure the desired vise effect with the jaw passive 24 on the bottom plate-copper plate assembly located in the right-of-way.
- a screw 31 for placing and removing the stirrup on the bottom plate is provided on the top, cooperating with an oblong passage light 32 to allow the necessary mobility play when tightening the side screw 29.
- the stirrup 22 exerts its action of tightening, not locally, but all along each large plate of the mold, or less on a substantial portion of it.
- the tightening function must be exercised sufficiently distributed so that the problems of local "hot" deformations of the wall of the mold encountered in conventional technology be abolished.
- the stirrup 22 is an elongated piece whose jaws 24 and 28 are of continuous grip over the entire length, the jaw active 28 being provided with a set of clamping screws 29 distributed over this length. We can thus have three or four stirrups juxtaposed one after the other depending on the width of the large face of the mold, or even a single stirrup which extends over this entire distance.
- This embodiment also makes it possible to provide a housing for receiving the counterweight. refractory 8.
- the lower part thereof is then cut into "L" of shape corresponding to the passive jaw 24 to be able to automatically position itself during installation on the stirrup desired, well aligned with the copper wall 9.
- This advantage is found in the insert in hard refractory 19 at the base of the riser.
- This insert 19, advantageously made of SiAlON, is not not in one piece over the entire width of the large plates 14, but made from elements juxtaposed kept joined together by tightening. We thus make a SiAlON bar of desired length much less expensive and much stronger than an equivalent monolithic bar that could be obtained commercially.
- FIG. 2 A clamping means integrated into the insert is visible in Figures 2.
- a bar 33 constituting the insert as it appears on each large faces of the mold.
- the insert 19 goes around the inner periphery of the mold. It is therefore, once mounted, in the form of a rectangular frame whose the sides, small and large, are formed by rectilinear bars 33 conforming to that shown here, each of length equal to the width of the wall of the ingot mold that receives it.
- the bar 33 is formed by assembling juxtaposed contiguous links 34 maintained rigidly clamped together by a clamping means, preferably integrated into the bar itself.
- this tightening means is a flange composed of a chassis frame with two sliding branches 44, 44 ′ associated with a tie rod crossing right through each link.
- This tie-rod comprises tightening nuts 36 screwed on its ends so to come, via the corresponding branch 44 of the chassis, compress a stack Belleville washers 43 bearing on the free lateral faces of the two links 34 at the end.
- the two branches 44, 44 ′ of the chassis slide one on the other in its central zone by two bearing surfaces 46, 46 'provided with oblong lights for the passage of a locking screw 47 which is fixed a once the links 33 have been tightened by the nuts 36.
- the tie rod 35 is in an offset position towards the "cold" rear face of the bar. 33 in order to move away from its "hot” face 37 intended to come into contact with the molten metal, therefore more thermally stressed.
- Such a clamping means is said to be "global action". Like a vice, it puts in compression mechanical all the links 34 by acting only on those located at the end of the bar. Of course, provision can be made to prestress each link individually to using the tie rod 35. For this, it is sufficient to have a threaded tie rod over its entire length is add intermediate nuts at the junction between two consecutive links.
- each link 34 comprises in fact two refractory portions: a body 38 crimped “hot” in a steel casing 39, and a head 40 which flourishes on the side of the "hot” face 37 of the insert while overflowing on both sides of the box 39.
- the lateral overhangs 41, 41 ′ are carefully surfaced to be able to apply tightly against each other from one link 34 to the next and do not offer joints 42 too wide into which the molten molten metal would infiltrate.
- the invention applies to the continuous casting not only of steel, but all other continuously castable metal and in particular metals with a lower melting point than steel that are aluminum or copper.

Description
- la figure 1 montre, en coupe verticale, la partie haute d'une machine de coulée continue de brames pourvue d'une lingotière conforme à l'invention, vue de coté;
- les figures 2 montrent 1' insert en réfractaire dur disposé à la base de la réhausse et constitué de tronçons jointifs assemblés, vu de dessus (fig.2a) et vu de face avant (fig. 2b).
- un manchon supérieur 18 en matériau réfractaire peu dense, choisi pour ses qualités thermoisolantes car il s'agit de conserver à l'état liquide la masse de métal coulé présent au sein de la réhausse. On optera pour un réfractaire fibreux, par exemple le matériau commercialisé sous la dénomination A 120K par la firme KAPYROK. Au besoin, une résistance chauffante pourra être incorporée;
- et un élément inférieur 19, appelé "insert", en matériau réfractaire dur, choisi pour sa bonne tenue mécanique, donc dense. Il s'agit en effet de résister au mieux, en cet endroit voisin du cristallisoir 7, à l'érosion mécanique de la pointe supérieure de la croûte solide 13 sur l'arête en cuivre 20, alors que l'ensemble est soumis au mouvement d'oscillation vertical habituel nécessaire à la réussite de l'opération de coulée, ainsi qu'aux sollicitations thermo-mécaniques d'une machine fonctionnant par cycles thermiques imposés par le caractère nécessairement séquentiel du procédé de coulée lui -même. Un matériau tel que du SiAlON (Sialon (R)), avantageusement dopé au Nitrure de Bore, pourra parfaitement convenir.
