Definitions
- the invention relates to continuous casting in charge of metals, especially steel. It relates more precisely to the casting in charge of elongated products, especially large sections, such as slabs, more commonly called "flat products”.
- the casting continues in load can be considered as an evolution of the casting process classic continuous, which aims to offset the height of the mold the place where solidification of the cast metal begins by contact with the inside face of the wall in cooled copper, from the place, located above, where is the free surface of the poured liquid metal (the "meniscus").
- the first solidification proceeds from a very physical mechanism sensitive, at the same time that it constitutes an essential factor of quality of the product obtained. Thanks to the separation of the levels specific to the casting continues in charge, this solidification takes place in a calm place on the plan of hydrodynamics, far from the always disturbed area that is the region meniscus.
- this separation of the two levels is made by overcoming the cooled copper body of the mold with a uncooled added extension made of refractory material with properties high thermal insulation (a kind of weight), well aligned internally with the ingot mold and within which the color will place and maintain the meniscus of the cast steel, spilled from a distributor arranged above.
- This insert must indeed be both good enough insulator from the heat to maintain the molten steel in the liquid state that it will contain at like the enhancer, and have good resistance properties mechanical to preserve the geometry of the the upper edge of the copper wall on which it rests, there precisely where solidification of the cast metal begins.
- material like SiAION® responds fairly well to this type of requirement opposite.
- the aim of the present invention is to provide a simple answer, reliable, and economical to the aforementioned difficulties encountered with casting of large section products.
- the invention relates to a mold head for the vertical continuous casting in charge of metals, steel in particular, comprising an extension of heat-insulating refractory material which overcomes the cooled metal crystallizer of the mold (usually in copper or copper alloy) by being internally aligned with it, and comprising, between the enhancer and the crystallizer, an insert of material dense refractory with mechanical resistance properties (SiAION for example) and shaped into a ring so that it can match the inner periphery of the mold, characterized in that said insert is consisting of bars, each bar being formed from a rigid assembly of juxtaposed and aligned contiguous elements, maintained clamped together by a clamping means integrated into said bar, and in this that means for aligning said bar with the body of the mold are provided and constituted by a pusher associated with a stop positioning on the cooled copper body and against which is supported by said assembly subjected for this purpose to the action of the pusher which tends to push it permanently towards the inside of the mold.
- connection angles generally right angles because the products cast continuously are usually rectangular section
- the means of integrated clamping consists of a transverse threaded tie rod in the long direction associated with clamping nuts (more generally clamping pads) provided at least in abutment on the free front face of the elements located at each end of the assembly.
- the tie rod is placed in an eccentric position towards the "cold" side of the assembly, that is to say its rear face opposite to the front "hot” face intended to be contacting the molten metal to be cast.
- intermediate clamp nuts are also provided for abutment against the internal front faces of the different elements so as to put in mechanical compression each elements in the long sense.
- the assembly of constituent elements of the insert is provided, in addition to the aforementioned overall clamping means, mechanical stiffening means of the "cold" side
- the invention consists, in its essential characteristics, to build a long straight bar of compact refractory (which will be assumed to be SiAION thereafter for fix ideas) from elements, possibly identical, in any case surfaced if necessary to allow their watertight junction, of course, and placed end to end one after the other over a distance corresponding to the desired length for the bar, then combined into a whole made rigid using clean clamping means designed to ensure also a mechanical reinforcement of the assembly.
- SiAION rod of desired length much less expensive and much more solid than an equivalent monolithic bar that one could get in trade. Consequently, this increased solidity makes it possible to retain rustic yet precise and reliable alignment solutions, such as "stop + push", which could not be applied to organs fragile or brittle.
- This ingot mold comprises, as can be seen, two stages 7 and 8.
- the lower stage 7 constitutes the crystallizer, also called "body” of the mold.
- This body in copper, or more generally in an alloy of copper, cooled by water circulation has an interior passage 9 for the cast metal, in which the latter in contact with the metal walls will gradually solidify from the periphery towards the center at as the PI cast progresses downward within the ingot mold.
- the crystallizer 7 itself is preferably formed of two parts superimposed: a main part 10, extended from above by a accessory part 11 well adjusted and aligned internally with the part low 10 to offer the cast product a regular and continuous passage.
- the lower part 10 is conventionally formed in the case of the continuous slab casting by four plates (or walls) assembled at right angle: two large walls 12 and 12 'facing each other and two small end walls, not visible in the figure. These four walls, the inner face of which is intended to come into contact with metal sunk, are energetically cooled by circulation of water along their outer face.
- a steel liner 13 is provided for short distance from each plate 12, 12 ′, for channeling a blade of water 14 preferably vertical circulation.
- the shirt 13 has at its ends of passages 15 and 15 ′ which bring the sheet of water 14 into communication with an introduction chamber 16 and with a chamber outlet 17 located above, delimited by an external partition 18 placed at a distance behind the shirt 13.
- the added upper part 11 forms a ring cooled by a internal water circulation in a channel 19 arranged as close as possible to its upper edge 20 on which the solidification of the metal will be initiated sunk.
- the role of ring 11 is precisely to protect well thermally this edge 20 which will be very thermo-mechanically stressed during casting by cooling it so significantly more efficient than the cooling system can do with water blade 14 of the main part 10 with assembled plates.
- the ring cooled 11 is surfaced at its base so as to match the surface well upper part of the tubular assembly 10 on which it rests, and thus avoid any risk of molten metal infiltration.
- the upper stage 8 is formed by an extension of material uncooled refractory, including the inner wall, for the same reasons as previously, is preferably aligned with that of the body of the crystallizer 7 (and in any case, not indented).
- the "metallic crystallizer” assembly cooled 7 surmounted by the insulating refractory riser 8 "defines a calibrating passage for the cast metal PI, the upper portion of which 21 at within the riser constitutes a buffer zone for the containment of hydrodynamic disturbances caused by the arrival of molten metal in the mold through the openings 5 of the nozzle 4, and the portion 9, which extends it downward, is a solidification zone of the cast metal.
- This solidification is initiated from the first contact of steel cast with the cold metal wall of the crystallizer 7, namely on the upper edge 20 of the copper ring 11, and continues towards downstream by forming a solid crust 22 whose thickness increases by periphery towards the center.
- the thick crust 22 a little over a centimeter, is strong enough to withstand the ferrostatic pressure of the still liquid heart and continues to grow centripetal until total solidification of the PI cast product under the effect of water spray bars, not shown, located in the lower half of the machine.
- the product obtained is cut in sections of desired length (the slabs) which are then available for further processing (rolling, etc.)
- This circuit comprises an annular slot 25 formed at the enhanced interface - crystallizer and opening at one end to the inside circumference of the mold and connected at its other end to a distribution chamber 26 supplied with argon by a tube calibrated 27, itself connected to a source of argon not represented by by means of a pressure vessel 28 enveloping the riser 8.
- This arrangement has the advantage of avoiding any risk of oxidation of the liquid metal poured into the mold by the oxygen in the air through of the insulating refractory mass 23 which is inevitably somewhat permeable.
- the SiAION 24 insert is, not in one piece, but made from juxtaposed contiguous elements held rigidly clamped together by a clamping means integrated in the insert.
- An embodiment is visible in Figure 2, which shows a bar constituting the insert as it appears on each of the large faces of the mold.
- the insert goes around the periphery inside of the mold. It therefore presents, once mounted, in the form a rectangular frame whose sides, small or large, are formed by rectilinear bars in accordance with that, 29, shown in FIG. 2.
- a bar 29 is formed by assembly juxtaposed contiguous elements 30 rigidly held together by a clamping means integrated into the bar itself.
- this tightening means specific to the bar is a compound flange of a tie 31 crossing right through each element passing in a passage 32 provided for this purpose in each of them, this tie rod, threaded at less at its ends protruding from the assembly, is associated with nuts clamp 33 screwed on these ends so as to bear on the free front faces of the elements 30 at the end.
- Such a clamping means is said to be “global action” because, like a vice, it puts in compression mechanical all the elements by acting only on the elements at the end of the bar.
- the tie rod is in an offset position towards the “cold” side of the bar (towards the bottom of the figure).
- the "cold face” the side of the insert opposite to it and therefore the least stressed thermally.
- the offset of the location of the tie rod 32 towards this cold face is intended to prevent the tie rod, generally made of steel, from overheating by being too close to the hot face, which would consequence a possible decohesion of the whole following excessive differential expansion phenomena.
- Such preferential compression of the cold face is of other interest.
- the refractory insert 24 is by destination a transition piece between the cooled metallic crystallizer 7 and the insulating refractory sleeve 23 it's necessarily a bad conductor of heat. So we will always have a thermal gradient significant between its warm side and its cold side. So it will always be also the site of significant differential expansion phenomena in its thickness. Compression prestressing preferential of its cold face will thus help to counteract the inclinations subsequent cracks, which otherwise could be caused by its pulling during expansion of the hot face in contact with metal in fusion.
- the offset of the tightening tie 31 still has the advantage additional to be able to reduce the thickness of the insert 24 if necessary, by example during hot face reconditioning operations after use.
- means of stiffening of the cold side of the bar are provided.
- This function can be simply provided by a shell 34 better visible in Figure 2.
- This shell in the shape of "L” at slightly acute angle, is made of spring steel: the bottom plate 35 is applied tightly against the cold face of the bar while being held there elastically by its side cheek 36 anchored in the material of the insert 24 using its folded edge 37 engaged in a notch provided for this purpose on the lateral face (here the upper face) of the bar.
- the correct positioning of the bar 29 within the mold consists in allowing its hot face 36 to come flush with the internal surface of the mold and this in a very regular manner over its entire length, which can reach and even exceed 1.5 m, depending on the width of the poured slab.
- this result is achieved by means of alignment of the bar, consisting in permanently pushing it elastically towards the inside of the ingot mold against a retainer secured to the upper copper ring 11 of the 7.
- such means can be simply constituted, on the one hand, by a battery of springs 38 placed facing the cold face of the bar and on which the springs act by taking their fixed support on the partition of the casing 28 , and, on the other hand, by a stop stop 39 come by machining of the upper face of the cooled ring 11.
- this stop is in the form of a tongue so as to constitute at the same time a partition delimiting the chamber 26 for distributing the flow of argon opening onto the inner periphery of the ingot mold just below the refractory insert 24.
- the underside of the bar 29 must also be machined in correspondence in order to provide a shoulder 40 visible in the view of FIG. 1 coming to cooperate with the stop 39.
- unitary elements 30 constituting a bar 29, and which can by elsewhere be all of the same length or not.
- several bars such as 24 can be placed end to end to occupy the width of a large face of the mold.
- the tightening tie crosses the elements 30. It is indeed possible, subject compatible space in this location of the mold, to provide a external tie along the cold side of the bar and provided at its ends of two jaws in the manner of a classic clamp.
- the invention applies to continuous casting not only steel, but any other metal capable of being cast continuously and in particular metals with a lower melting point than steel such as aluminum or copper.

Description
- la figure 1 est une vue en coupe verticale de la tête d'une machine de coulée continue de brames d'acier selon l'invention, faite suivant le plan médian perpendiculaire aux grandes faces de la lingotière;
- la figure 2 est une vue en coupe du dessus selon le plan de coupe A-A de la figure 1.
- un manchon supérieur 23 en matériau réfractaire choisi pour ses qualités thermo-isolantes, car il s'agit d'éviter toute solidification parasite prématurée du métal coulé dans la zone de turbulence 21. On optera pour un réfractaire fibreux, par exemple le matériau commercialisé sous la dénomination A 120K par la firme KAPYROK.
- et un élément inférieur 24, appelé "insert", en matériau réfractaire choisi pour sa bonne tenue mécanique, donc dense, car il s'agit de résister au mieux, au voisinage du cristallisoir 7, à l'érosion mécanique de la pointe supérieure de la croûte solide 22 sur l'arête 20 de l'anneau métallique refroidi 11, 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.
Bien entendu, la face inférieure du barreau 29 doit être également usinée en correspondance pour offrir un épaulement 40 visible sur la vue de la figure 1 venant coopérer avec la butée 39.
