Definitions

  • the present invention relates to the continuous casting of metals, especially steel. It relates more specifically to the technique known as "Continuous Pouring in Vertical Load” according to the preamble of claim 1 which is based on FR-A-2 704 786.
  • This "active” element is conventionally a tube, made in one piece (casting of billets and “blooms") or of assembled plates (casting of slabs or big “blooms”). It's copper, or copper alloy, energetically cooled by an intense circulation of water against its wall exterior in order to extract a sufficient heat flow to ensure solidification of the molten metal brought into contact with its inner wall.
  • the primary advantage sought by Continuous Casting in Load Vertical resides in the fact that one thus manages to distance the free surface metal cast in an ingot mold (the "meniscus"), which is then located within of the refractory riser, of the place where necessarily the solidification of the cast metal from the first contact with the cold wall of the mold body, i.e. at the edge of the end top of the copper element.
  • the aim is thus to continuously pour better semi-finished products.
  • metallurgical quality and with high extraction speeds or more than in Classic Continuous Casting because the solidification process then initiates himself in a calm environment in terms of hydrodynamics, all turbulence, in particular that caused by the arrival of the metal in fusion, remaining confined in the buffer volume offered by the extension refractory.
  • the object of the invention is precisely to avoid thermo-mechanical deformations from the upper end of the copper-cooled element to the during casting.
  • the invention relates to an ingot mold for casting Continues in Vertical Load of metals, steel in particular, comprising a tubular metallic element (copper or copper alloy) cooled, in particular by circulation of water against its outer wall, and intended to ensure the peripheral solidification of the metal cast in contact with its inner wall, and an uncooled riser of refractory material thermal insulation over the cooled metal element, intended to contain molten metal, and defining with it a continuous calibrating passage for cast metal, ingot mold characterized in that a metal ring, cooled by annular circulation of coolant, is reported between the tubular metal element and the thermally insulating extension, and of which the inner wall is full and aligned with said tubular element metallic without discontinuity between them so as to respect the character continuous passage offered by the mold to the cast metal.
  • a tubular metallic element copper or copper alloy
  • this ring is made of the same metal as the element tubular cooled, i.e. copper or copper alloy.
  • this ring is removably mounted so as to can be easily replaced.
  • the ring has an internal cooling circuit consisting of a chamber annular circulation of a cooling fluid which runs along the wall inside of the ring around the periphery of the mold, and preferably at immediate vicinity of this wall.
  • the invention therefore consists in its essential characteristics to be inserted between the mold tube and the refractory riser, a cold body, the ring, which in fact constitutes a extension of the main tubular element of which it is made of the same material, but having its own cooling circuit, and whose relative low height (compared to that of the tube) allows an efficiency of much better cooling than the system can do best cooling of the tube, at its ends, in particular of the edge of its upper end turned opposite the extension.
  • the tube of a continuous casting ingot mold makes usually 0.7 to 1.0 meter long, while the ring according to the invention is, for example, 4 to 10 centimeters high.
  • the cooled tubular element of the mold is replaced by a self-contained ring, preferably removable, also cooled, but whose cooling effect at its ends is naturally more effective due to its low height compared to that of the main tubular element of the mold and therefore the possibility of it install a cooling water blade running horizontally and not more vertically.
  • the invention overcomes this obstacle by means of an attached body, also intensely cooled, but low in height so that it can be install a horizontal coolant circulation and ensure thus both efficient cooling of its own upper edge at contact of the refractory riser to prevent its deformation at this place in contact with the molten metal, and the upper end of the tube of the mold with which it is in close contact through its underside.
  • the mold comprises, as can be seen, a tubular element in copper 4 energetically cooled by circulation of water along its face outside.
  • a steel jacket 5 is provided for this purpose, around and at a short distance from the tube 4, to channel a sheet of water to vertical circulation 21.
  • the jacket 5 has at its ends openings 22 which put the blade of water 21 in communication with a introduction chamber 6 and with an evacuation chamber 7, delimited by a coat 8 surrounding the shirt 5 from a distance.
  • the internal tubular element 4 is surmounted by an extension 9 in uncooled refractory material, the inner wall of which is preferably aligned with that of body 4 (and in any case, not indented).
  • the assembly "metallic element cooled 4 surmounted by the 9 "insulating refractory riser, defines a calibrating passage for the cast metal with the upper part 12 within of the extension constitutes a buffer zone, for the containment of hydrodynamic disturbances caused by the arrival of the metal jet 11 molten in the mold, and of which the lower part 13, which extends it, is a solidification zone for the cast metal.
  • This solidification is initiated from the first contact cast steel with the inner wall of the cooled copper body 4, know on the upper edge 14 thereof, and continues downstream in forming a solid crust 15 whose thickness increases from the periphery towards the center.
  • the crust 15, a little more than a centimeter is strong enough to withstand ferrostatic pressure of the still liquid heart 24 and continues its centripetal growth until total solidification of the cast semi-finished product 10 under the effect of the ramps sprinklers, not shown, located in the lower half of the machine.
  • the semi-finished product is cut into sections of desired length (billets, blooms or slabs, depending on the format of the casting section) and these sections are then available for further processing (rolling, etc.).
  • the tubular element 4 is surmounted by a ring 16, which extension, also of copper alloy and also cooled, but at using its own cooling system.
  • the latter in the example described consists of a chamber 17 running along the wall full inner 18 of the ring at a short distance.
  • This room here from circular shape, has its input / output adjacent to each other of on either side of a partition which closes off the room.
  • the cooled ring 16 is surfaced at its base so as to marry well the upper surface of the element 4 on which it rests, and thus avoid any risk of molten metal infiltration.
  • the cooled metal assembly formed by the ring 16 and the element tubular 4 constitutes the "active" part proper of the mold.
  • these two elements juxtaposed without discontinuity between them become one, because this is where solidification of metal begins cast and its growth as the cast 15 progresses towards the down inside this set.
  • the start-up plan for this solidification is no longer the plane passing through the upper edge 14 of element 4, but that passing through the upper edge 23 of the ring 16.
  • This 16-4 assembly is surmounted by the heat-insulating extension 9 seen previously.
  • a lost inert gas injection circuit (argon for example) is provided between the extension 9 and the metal assembly 16-4.
  • This circuit includes an annular slot 28 formed at the interface extension 9 - metal assembly 16-4 and opening at one end along the inner periphery of the mold and connected at its other end to a distribution chamber 29 supplied with argon by a tube calibrated 30, itself connected to a source of argon under pressure not represented.
  • this resistant lower ring 26 is inevitably less heat insulating than the upper part. So there is possible formation, in contact with its inner wall aligned 27 with that of the cooled ring 16, of a premature parasitic solidification veil of the cast metal. This veil is an important factor of heterogeneity with regard to the solidification process control in the cooled metal assembly 16-4. It is for this reason that, in accordance with an implementation advantageous of the invention and already known elsewhere (FR-A-93 03871), a Argon curtain is blown at the base of the riser 9 in order to break the parasitic solidification veil born on the ring 26 and allow a regular and frank start of solidification of the metal cast in contact with the cooled ring 16.
  • the tendency to stick the crust 15 against the wall of the ingot mold supplementing the known lubrication carried out by injection of a lubricant through the copper element 4 (see by FR-A-91 01551) by placing a in vibration using an ultrasonic transducer and applied to the free end of the upper return 32 of the cooled element 4.
  • This transducer may be of the "piezoelectric" type.
  • the obliquity of the direction of application of the ultrasound (see fig. 2) is not not mandatory. However, it has the advantage of combining an effect vertical vibratory with a horizontal vibratory effect, both contributing to reduce the friction of the product poured into the mold.
  • the invention applies to long products, such as flat products.
  • the invention applies to continuous casting not only steel, but any other continuously castable metal and in particular the metals with a lower melting point than steel such as aluminum or copper.
