Definitions

  • the present invention generally relates to an ingot mold for the continuous casting of metals, particularly for the continuous casting of metals such as steel.
  • the continuous casting operation schematically consists, as is known, in pouring a molten metal into a bottomless mold essentially consisting of a metal mold body, generally a one-piece tubular element (cast of long products) or with assembled plates ( casting of flat products) of copper or copper alloy, defining a passage for the cast metal and whose walls are vigorously cooled by circulation of water; and to extract continuously from this mold a product already solidified externally over several millimeters thick. The solidification then progresses towards the axis of the product and is completed during the descent thereof downstream of the mold in the so-called "secondary cooling" zone under the effect of watering ramps. The product obtained is then cut to length and rolled before shipment to customers or processing on site, bars, wires, profiles, plates, sheets, etc.
  • An important parameter of continuous casting is the energetic cooling of the mold body walls, which is necessary to extract the amounts of heat required for the solidification of the molten metal.
  • the cooling of the mold is done by circulating water along the outer face of the walls of the tubular body.
  • a steel jacket is provided for channeling the circulation around the tubular body, and communicates at its lower end with an introduction chamber and at its upper end with an evacuation chamber, so that the circulation of the water from bottom to top.
  • a rigid riser made of insulating refractory material is placed on the top of the tubular mold body to extend upwardly the internal passage of the metal tubular body in which the molten metal is cast. .
  • the level of the free surface of the molten metal also called meniscus
  • the volume of molten metal in the riser acts as a buffer, which dampens the flow turbulence that inevitably develops under the effect of the metal feed stream.
  • the use of the riser therefore makes it possible to obtain a flow of relatively quiet molten metal at the level at which its solidification begins, which contributes to a good quality of the solidified product and in particular to the regularity of the formation of the first skin upon contact with the cooled copper wall.
  • a recognized problem of the continuous casting under load is the difficulty of cooling well the upper part of the mold body, because the conventional cooling structure described above is not sufficiently efficient.
  • a first cooling circuit includes a plurality of vertical cooling channels distributed around the passage for the metal, in which water flows from bottom to top.
  • a lower distribution chamber ensures the introduction of water into the cooling channels
  • an upper distribution chamber collects water from the upper end of the channels.
  • the second cooling circuit comprises one or more cooling channels arranged horizontally between the upper end of the vertical cooling channels and the upper inlet face of the cooling channel. mold body.
  • the object of the present invention is to provide an ingot mold for the continuous casting of metals, simple design and having a high cooling capacity, especially at its inlet end. According to the invention, this objective is achieved by an ingot mold for the continuous casting of metals according to claim 1.
  • the present invention relates to an ingot mold for the continuous casting of metals, in particular steel, comprising a metal mold body having a passage for the cast metal extending between an inlet face and an outlet face. A plurality of cooling channels for a cooling fluid are arranged along the passage. A distribution chamber for the coolant communicates with the end of the cooling channels on the input side side.
  • the cooling channels extend as far as the inlet face, and their ends communicate with the distribution chamber via respective intermediate connecting channels.
  • the distribution chamber is arranged recessed with respect to the inlet face and with respect to the ends of the inlet side cooling channels.
  • the most critical hot zone of the mold is thus cooled by the cooling channels, which extend to under the entrance face, in the vicinity of it to form their end.
  • the distribution chamber is deported backwards and the cooling fluid is channeled between the end of each cooling channel and the distribution chamber by an intermediate connecting channel, typically oblique with respect to the direction of the cooling channel.
  • Such an intermediate channel thus constitutes a return line from the inlet face to the distribution chamber, which makes it possible to better preserve high cooling fluid speeds in the critical hot part of the mold.
  • the intermediate channels preferably have a section equal to or smaller than that of the cooling channels.
  • the channelization of the flow in the ingot mold part close to the inlet face and the offset of the distribution chamber prevent turbulence and other boiling phenomena, which are unacceptable for a stable casting process, which may occur.
  • the cooling channel opens directly into a distribution chamber of larger section.
  • the configuration of the mold according to the invention therefore allows the mold body to be cooled further towards its inlet end, which makes it particularly suitable for continuous casting under load, in particular the continuous casting in vertical load of the mold. 'steel.
  • a cooling circuit according to the invention can easily be realized with ingot mold bodies of various sizes and shapes.
  • the present invention particularly relates to ingot molds for the continuous casting in vertical load of small sections, typically of dimensions 100x100x12 mm to 300x300x20 mm with casting speeds in the range of 5 to 10 m / min.
  • another distribution chamber communicating with the end of the cooling channels is provided for side of the exit face.
  • the end of each cooling channel on the exit face side is in communication with this other introduction chamber through a respective passage.
  • the passage section in the cooling channels is reduced near the inlet face of the mold body. This makes it possible to increase the speed of the cooling fluid in this region of the mold body, and thus to increase the cooling capacity. Such a reduction of the passage section can be obtained by machining.
  • the section reduction is preferably done by means of a section reducing device which is installed in the end of each inlet side cooling channel.
  • the section reducing device is advantageously designed so as to partially close the cooling channel near its cold face (farthest from the casting space) and allow the flow of cooling fluid along the hot face ( thermally charged) of the cooling channel.
  • Such a section reducing device therefore makes it possible to increase the speed of the cooling fluid in the critical part of the mold body, and to circulate the fluid in the portion of the hottest cooling channel.
  • the section reduction device comprises an oblong body with three faces: a convex face whose curvature corresponds to that of the cooling channel, and two concave faces contiguous to the convex face and meeting at the level of the 'a stop. Viewed in cross section, the maximum distance between the edge and the convex face is substantially equal to the section of the cooling channel.
  • the section reducing device is oriented in the channel so that its edge is turned towards the hot channel, so that the cooling fluid is forced to flow in two reduced section channels along the hot face of the cooling channel.
  • the elongate body is extended at its lower end by a tapered foot, the height of which is greater than the distance between the end of the cooling channel on the outlet side and the opening of the intermediate channel. coming into this area.
  • This foot avoids clogging of the intermediate channel close to the exit face, should the device fall to the bottom of the cooling channel.
  • the convex face When the section reducing device is positioned in the cooling channel with its edge against the hot face, the convex face is against the cold face of the cooling channel. It is usually in this cold face that opens the intermediate channel on the side of the input face. Therefore, in each concave side face, a passage hole connecting the latter to the convex face will preferably be provided to allow the flow of the cooling fluid directly into the intermediate channel.
  • the cooling channels preferably extend substantially the entire length of the passage (or casting space) in the mold body. In addition, they advantageously follow the contour of the passage, which depends on the metal product to be cast (slab, beam, or other profile).
  • the passage section provided by the cooling channels is preferably identical and constant over their entire length, except, where appropriate, near the inlet face where the passage section can be reduced as indicated above.
  • the mold body depends on the type of metal product to be cast.
  • the mold body will generally comprise a monolithic tubular element of copper or copper alloy.
  • the cooling channels are preferably drilled in the wall of this monolithic tubular element and distributed all around the passage.
  • the mold body generally comprises a four-plate assembly defining a rectangular passage for the cast metal.
  • the cooling channels with the intermediate channels are arranged in at least one of said plates.
  • the mold will typically comprise a riser comprising a rigid refractory element thermally insulating property extending the passage of the ingot mold body above the inlet face.
  • a gas preferably inert
  • the present invention relates to an ingot mold for the continuous casting of metals
  • a mold body having a passage for the cast metal and at least one cooling cooling channel along the passage, wherein a Section reducer device is installed in the cooling channel.
  • the section reducing device closes the channel along the cold face and allows the flow of cooling fluid along the hot side of the cooling channel.
  • the Fig.1 shows a schematic section of an ingot mold 10 according to the present invention, in an application to continuous casting in vertical load steel.
  • the mold 10 comprises an ingot mold body 12 having an upper inlet face 14 and a lower outlet face 16, and which is provided with a passage 18 for the molten metal defining the casting space extending between the input face 14 and output face 16.
  • the ingot mold body 12 is surmounted by a riser, generally indicated 20, in which the molten metal is poured from a tundish (not shown), and which makes it possible to maintain the free surface of the metal by melting at a distance from the mold body 12 where the solidification begins.
  • the riser 20 takes place on the upper end of the mold body 12 and is in fact made up of two aligned tubular elements: a lower element, ring 22, compact refractory material having a good mechanical strength such as SiAION; and an upper element, sleeve 24, made of a thermally insulating refractory material.
  • the mold body 12 is vigorously cooled by circulating water internally to extract the heat necessary for cooling the molten metal.
  • the cooling water circulates, preferably upwardly, in a plurality of vertical cooling channels 26 (only one shown in FIG. Fig.1 ) to the periphery of the passage 18.
  • the lower end of each cooling channel 26 communicates with a so-called introduction distribution chamber 28, which allows the introduction of the cooling water into the channels 26 with a suitable pressure to establish the desired speed of circulation.
  • the water thus rises in the cooling channels 26 along the passage 18, and is collected after its exit from each channel 26 in another so-called evacuation distribution chamber 30 (of section substantially greater than the channels 26).
  • evacuation distribution chamber 30 of section substantially greater than the channels 26.
  • the cooling channels extend as far as the inlet face 14 of the mold body 12, which makes it possible to have cooling channels 26 which extend almost the entire length (height) of the passage 18, and therefore especially in the upper region of the mold body 12 towards the interface with the riser 20 where the solidification.
  • the evacuation chamber 30 is set back with respect to the inlet face 14 of the ingot mold body 12 and at the upper end of the cooling channels 26. The circulation of the water from the end of the cooling channel 26 on the inlet side face 14 to the evacuation chamber 30 is made through an intermediate evacuation channel 32 (or intermediate connecting channel) which leaves the end of the channel 26 and departs from the inlet face 14 towards the rear to open into the remote evacuation chamber 30.
  • the intermediate connecting channel 32 thus extends obliquely with respect to the axis of the cooling channel 26 with which it is associated.
  • Such an intermediate connecting channel 32 thus constitutes a return line from the inlet face 14 towards the distribution chamber, which makes it possible to maintain high cooling fluid velocities up to the evacuation chamber 30.
  • the structure of the cooling circuit in the mold 10 allows to evacuate large amounts of heat in the critical hot zone of the mold, and avoids the problems of evaporation and dead zones in this part of the mold.
  • the mold body comprises, assembled to each other, a bottomless monolithic tubular element 33 made of copper or copper alloy, defining the casting space in the form of a central passage 18 for the cast metal and a mantle 39 surrounding the element 33 at a distance.
  • This tubular element 33 has an upper flange 34 whose free end comes into sealing contact with the upper edge of the mantle 39 and whose upper face constitutes the inlet face 14 of the casting space 18.
  • the mantle 39 has at its lower end a return flange 36 coming from its free end in sealing contact with the lower edge of the tubular body 33 and whose lower face constitutes the outlet face 16 of the casting space 18.
  • 28 introduction and evacuation rooms 30 are delimited laterally by the mantle 39 and frontally by the lower flanges 36 and upper 34 respectively. They are arranged one above the other, separated by a watertight partition 37 coming from the construction of the tubular element 33 and cooperating at its end with a corresponding bearing surface 31 of the mantle 39 with the interposition of a seal toric 25.
  • the hydraulic communication between the introduction chamber 28 and the cooling channels 26 is through passages 38 drilled in line with the tubular element 33 flush with the bottom of the chamber 28.
  • the communication between the channels 26 and the evacuation chamber 30 is effected by means of intermediate connecting channels 32 obliquely drilled in the upper flange 34 in order to connect the upper outlet end of each cooling channel 26 to the exhaust chamber 30 at its upper end.
  • intermediate connecting channels 32 are made as short as possible by piercing them, as shown in FIG. Fig.1 at the location of the connection fillet 35 between the upper flange 34 and the tubular element 33.
  • the cooling channels 26 can be easily made by drilling from the lower face 16 in the wall of the tube. The channels 26 are then closed on the outlet side by plugs 40. Similarly, the intermediate discharge channels 32 may be made by drilling the upper flange 34. Drilling is still the preferred solution for the intermediate inlet channel 38 .

  • the passage 18 of the ingot mold body 33 has a shape (section) adapted to the casting of beams.
  • the cooling channels 26 are uniformly distributed all around the passage 18 and follow the shape. In the present variant, they have an identical and constant section over their entire length. As can be seen, the cooling channels extend as far as the upper face 14 of the flange 34, and the evacuation channels 32 extend from the upper end of the channels 26 through the flange 34 to open into the top of the discharge chamber 30.
  • the section of the intermediate channels 32 is preferably not greater than the maximum passage section of the cooling channels 26.

  • the structure of the cooling circuit in the present mold 10 is particularly well suited for mold bodies of reduced size and complex shapes, such as for the manufacture of small sections.
  • the use of a plurality of channels of relatively smaller cross-section, uniformly distributed makes it possible to better distribute the heat extraction, and thus to obtain a better homogeneity of cooling on the perimeter.
  • the vertical cooling channels have for example a diameter between 7 and 10 mm, and their upper end is located unless 8 mm of the input face 14 (upper surface of the flange 34), preferably between 4 and 6 mm.
  • the distance between the hot face of the channels 26 and the inner face of the passage 18 may be between 5 and 10 mm.
