Definitions

the invention relates to the field of continuous casting of metals. More specifically, it relates to the lubrication mode of the ingot molds of conventional continuous casting installations, and also of the ingot molds of so-called “continuous casting under load” installations, in which it is sought to move the surface of the liquid metal in the ingot mold away from the area where solidification of the cast product begins.
the conventional continuous casting operation of steel schematically consists in continuously pouring the molten metal into a bottomless vertical oscillating tubular ingot mold, with metal walls (copper or copper alloy) energetically cooled by internal circulation of water, and to extract therefrom, also continuously, a product (slab, bloom or billet according to the dimensions of the mold) already solidified externally over a few centimeters in thickness.
a product sin, cast, bloom or billet according to the dimensions of the mold
the solidification of this product is completed in the lower stages of the machine, where the product is first, on leaving the ingot mold, forcedly cooled by spraying water, then cools naturally. It is then cut to the desired length.
the oscillation of the mold has the function of preventing the solidified skin of the product from sticking locally to the wall of the mold, which would tear the skin causing a "breakthrough", that is to say the flow of liquid metal by this tear.
the consequence of such an incident would be the need to immediately stop the casting, and the risk of causing serious damage to the machine.
a known remedy for this problem consists in moving the surface of the liquid metal in an ingot mold away from the level at which solidification of the product begins.
an uncooled tubular element called “enhancer”
the flow rate of metal introduced and the speed of poured to maintain the surface of the metal inside the riser.
This being made of a heat insulating material such as an aluminous refractory, the solidification of the skin of the product does not start in principle not on its walls, and begins only at the metal element. Fluctuations in the level of the liquid metal surface no longer affect the area where solidification begins. This is carried out very regularly and leads to a surface and subcutaneous quality of the products, a marked improvement compared to conventional continuous casting installations. Such installations are usually designated by the term "continuous poured laden".
the submerged nozzle which brings the liquid metal into the ingot mold, at its open end held inside the extension.
the metal which it contains therefore constitutes a buffer volume which dampens the turbulence due to the incoming flow of metal, before it reaches the level of the metallic element. This also contributes to providing greater regularity in the solidification of the first layers of metal than in the case of conventional continuous castings, where these turbulences affect the entire upper part of the cooled metal element and can slow solidification in the vicinity of the zones of strong recirculations.
this powder ensures the capture of non-metallic inclusions which have risen to the surface of the metal, protection of the liquid metal against atmospheric reoxidation and arrest of the radiation emitted by the metal.
the requirements on the composition of the powder which notably governs its fluidity at the powder / metal interface, are not identical for all these functions. The choice of composition is therefore necessarily a compromise which does not make it possible to ensure any of them optimally.
the other lubrication method consists of depositing on the surface of the metal in the mold a layer of oil, such as rapeseed oil, so that it infiltrates between the wall and skin solidified.
the first cannot be transposed to the case of load casting.
the powder which must be deposited on the surface of the metal in the enhancer to protect the metal and catch the inclusions cannot reach the upper edge of the metallic element, where the solidification of the skin begins, and therefore has no role in lubrication.
it is not conceivable to inject powder at the junction between the riser and the metallic element because one would cause pollution of the metal by the fraction of the powder which, inevitably, would be entrained within it. It is therefore chosen to provide lubrication of the mold by an injection of oil carried out on the internal periphery of the metal element, in the vicinity of its junction with the extension.
the object of the invention is to propose a method allowing optimal lubrication of the whole of the cooled metal part of the ingot mold of any continuous casting installation, in that it would make possible in all cases the use of a liquid lubricant on a conventional continuous casting, and in that it would simplify the design of the molds for continuous casting under load.
the subject of the invention is a method of lubricating a mold for continuous casting of a metallic product of the type comprising a metallic tubular element oscillating vertically energetically cooled, defining a passage for the cast metal, and intended to cause in contact with its wall in said passage the solidification of said metallic product, according to which an injection of a lubricant in the liquid state is carried out through said metallic tubular element in the direction of said metallic product in the course of solidification, characterized in that said injection is carried out at points distributed annularly on a single level of said tubular element, said level being located at a distance greater than 20 cm from the lowest level where the solidification of said product is likely to be initiated, and in that the flow rate of said lubricant is sufficient to cause a rise of a fraction of said lubricant along from said wall to the level where the solidification of said product actually begins.
the invention also relates to an ingot mold for a continuous casting installation of metallic products, of the type comprising an energetically cooled metallic tubular element, defining a passage for the cast metal, and intended to cause contact with its wall in said passage. solidification of said metallic product, means for vertically oscillating said ingot mold, and means for injecting a lubricant in the liquid state through said metallic tubular element in the direction of said metallic product being solidified, characterized in that said means are placed at a single level of said metallic tubular element, said level being located at a distance greater than 20 cm from the lowest level where the solidification of said product is likely to be initiated.
the invention consists in locating the injection of liquid lubricant at a level of the mold located very substantially lower than the level at which the solidification of the cast product begins, and not at this level itself.
the inventors have in fact found that the vertical movements of oscillation of the mold could be sufficient to cause a significant rise of a fraction of the lubricant along the walls of the cooled metallic element.
By appropriately adjusting the location and parameters of the lubricant injection it is therefore possible to send a significant quantity of it to the level where solidification begins, and thus ensure satisfactory lubrication of the mold on the entire height of its cooled metal element just with this injection. This quantity must, on the other hand, be moderate enough not to cause unacceptable gas emissions in the mold.
the covering powder is no longer used for this lubrication function and it is therefore possible to optimize its composition to make it best fulfill its functions of trapping inclusions and protecting the surface of the liquid metal.
the mold 1 shown in Figure 1 is, as is conventional in continuous casting in charge of steel or other metals, composed of two superimposed elements.
the main one is a metallic tubular element 2 made of copper or copper alloy, the internal surface 3 of which defines a passage 4 of dimensions identical to those of the product which it is desired to pour, and of round, square or rectangular cross section.
This metallic tubular element 2 can consist of a single piece (this is most often the case for the casting of rounds, billets and steel blooms), or be formed by an assembly of plates, each of which corresponds to one face of the mold 1 (general case for the casting of steel slabs).
the metallic tubular element 2 is cooled by a circulation of water 5, formed for example between its external surface 6 and a jacket 7 which surrounds it.
the second element of the ingot mold On the upper edge 8 of the metallic tubular element 2 is fixed the second element of the ingot mold, namely an extension 9 formed by a tubular element in a refractory material such as a 90-10% alumina-silica mixture.
the internal surface 10 of the extension 9 defines a passage 11 situated in the extension of the passage 4 defined by the internal surface 3 of the metallic tubular element 2.
these two passages 4 and 11 have the same dimensions, but it can be provided that one of them has a smaller size than the other, to make the start of solidification of the cast product more frank.
a submerged nozzle 12 connected to a distributor (not shown) containing the liquid metal 13 to flow causes the latter in the internal passage 11 to the riser 9.
the solidification of the liquid metal 13 does not occur significantly on its walls., And does not start until the liquid metal 13 comes into contact with the internal surface 3 of the cooled metal element 2, ie at the upper edge 8 of said element 2.
This solidification results to the formation of a solidified steel crust 14, of increasing thickness as one descends into the mold 1, surrounding the core 15 still liquid from the cast product 16.
This product 16 is continuously extracted from the ingot mold 1 by a known device not shown, installed in the lower stages of the machine.
the cooling of the product 16, after it leaves the mold 1 in the partially solidified state conventionally continues using a device (not shown) for spraying with water jets or a water / air mixture from its external surface.
the ingot mold 1 also comprises, in a conventional manner, a device not shown making it possible to print vertical oscillation movements as a whole according to arrow 17. These oscillations can be sinusoidal or obey a more complex law. They usually have a frequency of a few Hz, and an amplitude of a few mm.
the ingot mold 1 also comprises a device ensuring the lubrication of the internal surface 3 of the cooled metallic tubular element 2, by injection on the periphery of this surface of a lubricating liquid, such as oil, intended to be inserted between this surface 3 and the solidified crust 14 of the product 16.
a lubricating liquid such as oil
This injection is carried out through channels 18, 19 formed in the walls of the element metal 2, and leading the lubricant to orifices 20, 21 opening onto the internal surface 3 of this element 2, so as to distribute it over the entire periphery of the solidified crust 14 of the product 16.
the lubricant is itself brought into the channels 18, 19 by means not shown connected to the lower orifices 22, 23 of the channels 18, 19, opening onto the lower edge 24 of the cooled metallic element 2.
the conventional continuous casting installation according to the invention shown in FIG. 2 has its elements equivalent to elements of the same nature and of the same function of the installation in FIG. 1 identified by the same references.
This installation differs from the previous one in that the cooled metallic tubular element 2 constitutes the entire internal face of the ingot mold 1. There is therefore no longer any heat insulating enhancement.
the surface of the liquid metal 15 present in the mold 1 is maintained below the upper edge 8 of the metal element 2, and it is at its level that the solidification of the crust 14 of the product begins.
the lubrication of the internal face of the ingot mold 1 is entirely ensured by an injection of lubricating liquid carried out at a distance from the level at which the solidification of the crust is initiated 14.
this injection must be carried out at least 20 cm below the surface of the liquid metal 15. It is therefore necessary to place the lubricant injection device at least 20 cm below the lowest level where solidification of the product is likely to begin 16.
the lubricant must also be injected at a rate such that, taking into account the other operating conditions, at any time a significant fraction of the lubricant rises along the sides. of the cooled tubular element 2 to the level where the solidification of the product 16 actually begins.
the essential advantage of such a technical solution, in conventional continuous casting, is to authorize the use of a covering powder 25, the composition of which is particularly suitable for trapping inclusions and for isolating the liquid metal 15 from the atmosphere, since it does not have to ensure the lubrication of the ingot mold 1.
a covering powder 25 the composition of which is particularly suitable for trapping inclusions and for isolating the liquid metal 15 from the atmosphere, since it does not have to ensure the lubrication of the ingot mold 1.
Such an adaptation leads to the choice of a powder 25 having at its interface with the liquid metal 15 a less fluidity than that which would be necessary on a traditional classic continuous casting.
FIG. 3 presents a more detailed view of a nonlimiting example of embodiment of the metal element 2 of the mold 1, freed from the jacket 7 which surrounds it when it is installed in the casting machine.
This example is suitable for the casting of steel products with a square cross section of 155 mm side.
the lubricant supply channels 18, 18 ′ are formed by longitudinal grooves machined on the external surface 6 of the metal element 2 in the extension of holes made in its lower edge 24 which constitute the lower orifices 22, 22 ', 23, 23' of the channels 18, 18 ', 19.
These channels 18, 18', 19 each open, at their upper end, into a distribution chamber 25, 25 'constituted by a machined recess transversely to the channel 18, 18 ′, 19 corresponding on the external surface 6 of the metal element 2, and which extends up to the proximity of the edges 26, 27, 28 of said element 2.
the bottom of each of these chambers distribution 25, 25 ' is pierced with a multiplicity of small holes 20, 20', 21 which open on the internal face 3 of the metallic element 2 and constitute the aforementioned orifices which bring the lubricant between the metallic element 2 and the solidified rind 14 of the product t cast 16.
the channels 18, 18 ', 19 and the distribution chambers 25, 25', after their machining, are closed in leaktight manner by covers (not shown) which are fixed to the external face 6 of the element metallic 2, for example through electron beam welding.
This fixing method has the advantage of authorizing the application of ultrasound to the mold 1 without deterioration of the tightness of the cover-metal element connections 2, which would not be possible if this fixing was carried out using quote. It will be recalled that ultrasound can, in known manner, contribute to improving the lubrication of the mold 1 and increase the efficiency of its cooling system.
fine longitudinal grooves 29 are formed on the internal face 3 of the metal element 2, between its lower edge 24 and the distribution chambers 25, 25 'of the lubricant, in line with the orifices 20, 20', 21. These grooves facilitate the evacuation of excess lubricating liquid and gases resulting from its cracking towards the lower part of the mold 2.
the parameters to be taken into account for the determination of the optimal place of injection of the lubricant in a mold of given format are essentially the speed of casting of the product 16, the amplitude and the frequency of the oscillations of the mold 1 and the flow of lubricant injected. All other things being equal, the lubricant rises along the metallic element 2 over a height which is all the more important as its flow rate is high and the speed of casting is low.
the ingot mold 1 must therefore be designed so that, just by acting on the flow of lubricant, it is possible to obtain correct lubrication of the whole of the ingot mold 1 for all the operating conditions under which it is capable of be used.
