Definitions

  • the present invention relates to a continuous casting device between cylinders comprising a cover for inerting the casting space defined between said cylinders.
  • a known problem is that the metal contained in the casting space tends to cool on the surface and thus to create parasitic solidifications which affect the proper functioning of the installation. to remedy this problem, it has already been proposed to place a thermally insulating cover above the casting space.
  • document EP-A-0409645 describes an installation in which channels for injecting an inert gas are arranged against the longitudinal side walls of a cover covering the pouring space, these channels comprising a slit directed towards the surface of the cylinders, so as to blow said inert gas towards this surface, in order to remove the film of air entrained therefrom by the cylinders during their rotation, and particularly the air contained in the roughness hollows of said surface, this in order to prevent said air from entering the casting space and therefore to maintain a non-oxidizing atmosphere there.
  • the said channels can be partitioned.
  • an external cover is fixed to the lower edge of the side wall of the cover and positioned adjacent to the surface of the cylinders, and has at its external edge a gas supply channel inert, this in order to prevent air from entering the pouring space even more effectively, since the interior of said cover is filled with inert gas.
  • the present invention aims in particular to solve these problems and aims in particular to propose a rollover system making it possible to ensure reliable inerting of the pouring space, effective control of the nature and quantity of the gas provided by the roughness surface of the cylinders, which influences, by remaining trapped in the roughness hollows between the cylinders and the skin of solidified metal, on the heat flux between said metal and the walls of the cylinders, and therefore on the solidification conditions and on the form of said walls.
  • the invention relates to a continuous casting device between cylinders comprising two counter-rotating cylinders, with parallel axes, defining between them a casting space, a casing placed above the casting space and comprising two longitudinal walls which extend respectively along the surface of each cylinder and which are provided with gas supply conduits leading to said surfaces, characterized in that each wall comprises sealing means by loss of load, to create a pressure drop in an area between said wall and the surface of the cylinder corresponding and between two of said conduits, so that the gas flow supplied by the conduit located upstream, relative to the direction of rotation of the cylinder, is directed towards the outside of the cowling, and the gas flow supplied by the conduit located downstream is directed towards the pouring space.
  • the said means for sealing by pressure drop are formed by a projection of the wall extending between the said conduits up to direct proximity to the surface of the cylinder, and they can comprise longitudinal grooves, parallel to said conduits; these grooves, being located in the direct vicinity of the surface of each cylinder, constitute therewith, a series of baffles accentuating the pressure drop between the conduits.
  • the conduits are drilled in the said walls and the said orifices preferably consist of a continuous slit along the length of said conduits, or of several adjacent slits, and the conduits comprise, at least in the region of said orifices opening out opposite the surface of the cylinder, a porous material.
  • the device comprises means for controlling the position of the cowling relative to the surface of the cylinder.
  • These means comprising for example position sensors linked to the cowling and measuring the variations in distance from the surface of the cylinders relative to said cowling, and jacks for adjusting the position of the cowling relative to the chassis of the device, make it possible to maintain the conduits and especially the sealing means by pressure drop at a substantially constant distance from the surface of the cylinders, when the latter is deformed by thermal expansion, so that the pressure drop between the conduits remains substantially constant and as high as possible.
  • FIG. 1 and 2 there is shown schematically, in section along a plane perpendicular to the axes of the cylinders, the molten metal supply zone of a continuous casting installation.
  • This installation comprises two casting cylinders 1, 2, the external wall 3 of which, conventionally consisting of a ferrule, is vigorously cooled.
  • the cylinders 1 and 2 are rotated according to arrow F.
  • a cover 4 for inerting and thermal insulation is located above the casting space 5 defined between the two cylinders.
  • the cowling is connected to a distributor 6 containing the molten metal, on which is fixed a feed nozzle 7 which extends vertically into the casting space 5.
  • Sealing means 8 such as for example a drawer system of a type known per se, are placed on the distributor, in order to be able to close off the nozzle 7.
  • the cowling 4 is tightly connected to this drawer system by sealing means 9, surrounding the nozzle, for example, as shown in the figures 1 and 2, a sand joint system; these sealing means allow a slight offset, if any, between the distributor and the casting installation, while retaining the required seal, and therefore make it possible to simultaneously inert the nozzle.
  • the cowling 4 is held on the installation by adjustable support means 10, in particular in height, so that the longitudinal walls 41 of the cowling are held above the ferrules 3 of the cylinders, at a short distance from their surfaces.
  • the longitudinal walls 41 therefore extend parallel to the axes of the cylinders 1, 2, over the entire width of the ferrules, and bear on their face directed towards the inside of the cowling, a thermal protective coating constituted for example by refractory elements 42 which extend down below said longitudinal walls 41 to near the surfaces of the cylinders, so as to protect said walls from the thermal radiation of the molten metal contained in the casting space.
  • a sealed cover 43 provides the connection between the longitudinal walls 41 and the sealing means 9.
  • the cover 43 has front walls 44 which extend vertically up to the lateral closure walls 11, conventionally placed against the edges of the cylinders to close the casting space towards said ends of the cylinders.
  • these closure walls generally comprise a metal casing 12, of which only the upper part is shown in FIG. 2, which supports a refractory coating 13 applied against the edges of the ferrules 3.
  • Dynamic sealing means 14 are provided between the lower ends of the front walls 44 of the cowling and said lateral obturation walls 11, these dynamic sealing means preferably being constituted by a baffle sealing system, which makes it possible to provide sealing by pressure drop without direct contact between the casing 12 and the cowling 4. Thus, a satisfactory seal can be obtained despite the movements of the lateral closure walls 11, which are inevitable during casting.
  • Sealing means of similar type, not shown, are also provided between the end edges of the longitudinal walls 41, and the said lateral obturation walls 1.
  • Each longitudinal wall 41 of the cowling comprises two conduits 45, 46 which are mutually parallel and extend in the direct vicinity of the wall of the cylinders and over the entire width of the latter.
  • Each of these conduits opens laterally, through respective orifices 47, 48 produced in the form of longitudinal slots, at the lower surface 49 of the wall 41, opposite the surface of the cylinder.
  • sealing means are provided by pressure drop, formed for example simply by a part 50 from the wall, projecting towards the cylinder with respect to said conduits. This projecting part is shaped so as to create a significant pressure drop for gases supplied between the wall and the surface of the cylinder.
  • the slots 47, 48 open in a direction inclined relative to the surface of the cylinders, the inclination of the slots 47 of the duct 45 located most upstream relative to the direction of rotation of the cylinder 1 being directed towards the outside of the cowling, so that a flow of gas leaving these slots is directed almost exclusively towards the outside, while the slots 48 of the duct 46, located downstream, are preferably directed towards the casting space.
  • an inert gas under pressure is introduced into the duct 45, it is directed through the slots 47, towards the surface of the cylinder 1, and in the opposite direction of the rotation of the latter, in order to oppose penetration outside air in the pouring space.
  • a brush 51 is located against the external face of the wall 41 to limit the amount of air supplied under the longitudinal wall due to the rotation of the cylinders, and in particular to protect the said wall from ascending hot air currents generated by rotation.
  • Blowing means 52 are arranged still upstream of the brush 51, to direct a gas jet towards the surface of the cylinder 1, also against the direction of rotation of the latter.
  • the duct 45 and the slots 47 make it possible to bring to the interface between the longitudinal wall 41 of the cowling 4 and the cylinder a flow of gas directed towards the outside of the cowling, and which , in combination with the blowing means 52 and the brush 51, opposes the passage of air, driven with the cylinder in rotation, towards the casting space, while the conduit 46 makes it possible to bring directly against the surface of the cylinder an inerting gas or a gaseous mixture of predetermined characteristics, which can be adapted as a function of the casting conditions, and the small distance between the projecting part 50 and the surface of the cylinder creating a sufficient pressure drop in the zone 22 between the two conduits to ensure the best possible seal between them.
  • the longitudinal walls 41 are surmounted by a frame 53 to which they are linked, this frame also being internally coated with a thermal protection refractory 54.
  • the support means 10 for the cowling are fixed to this frame and rest by by means of jacks 55 on crosspieces 56 of the framework of the installation.
  • the sleepers 56 also carry windbreak systems 57 comprising a lip 58 disposed as close as possible to the surface of the cylinders but without contact, these windbreakers having the purpose of protecting the longitudinal walls 41 from the hot air currents which surround the cylinders during casting.
  • a heat shield 59 consisting of a plate of refractory material extending substantially horizontally and connecting said elements 42, an orifice 60 being provided in this plate for the passage of the nozzle 7.
  • the frame 53 is surmounted by the cover 43, which is connected to the drawer 8 of the distributor by a sealing means having a certain flexibility and having an adjustable height, such as the bellows 61.
  • the cover may also include various accessories such as porthole 62, or supports for metal level measuring devices in the pouring space, etc.
  • Sensors 63 for non-contact distance measurement are placed on the longitudinal walls 41, near the cylinders, for permanently measuring the distance of said walls 41 relative to the surface of the cylinders , and order the jacks 55 to maintain this distance constant.
  • These sensors could be replaced by any other means enabling the position of the cowling to be enslaved relative to the position of the surface of the cylinders in the area adjacent to the conduits 45, 46.
  • the conduits 45 and 46 preferably comprise a porous material making it possible to homogenize the distribution of the gas supplied into these conduits over their entire length.
  • tubes 72, 73 of such a porous material are placed for this purpose respectively in the conduits 45, 46, the gas being brought inside these tubes and distributed evenly over the length of the conduits during its passage through said porous material.
  • FIG. 4 represents this wall in section on an enlarged scale.
  • the gas supplied in the conduit 46 located further downstream, escapes from this conduit through the orifices 48 by creating another laminar current (arrows F2) in the same direction as the rotation of the cylinder.
  • the two gas streams (F1, F2) are, at the interface between the wall 41 and the surface of the cylinder, separated by a practically stationary gas partition retained in the zone 22 by the baffles formed by the grooves 64 produced on the lower surface of the wall 41, between the two conduits 45, 46, and parallel to these.
  • this gas partition generating a pressure drop between the outlets of the conduits at the lower surface 49 of the wall 41, can only have its effect if the distance between this surface 49 and the wall of the cylinder is sufficiently small, which requires being able to keep this short distance during casting, despite the expansion deformations of the cylinder, by acting on the jacks 55 for positioning the height of the cowling.
  • the distance j1 between the cylinder and the lower surface 49 of the wall 41, upstream of the duct 45 is preferably less than or equal to 2 mm
  • the corresponding distance j2 downstream of the duct 46 is less than or equal 2.5 mm
  • the distance j3, at the level of the zone 22, is less than or equal to 1.5 mm.
  • the flow of gas which enters the casting space is divided into a flow Q 1 which remains in the boundary layer attached to the cylinder, penetrates between the surface of the cylinder and the cast metal and therefore intervenes in the heat exchange between the latter, and a flow rate Q 2 which passes over the surface of the bath of cast metal and ensures its inerting.
  • a third flow Q 3 escapes towards the upper part of the cowling, through orifices 65 made for this purpose in the refractory lining 42 and / or the heat shield 59, to prevent too much flow from reaching the meniscus of cast metal, which could lead to gas saturation of the said metal and cause it to cool.
  • the device comprises adjustment and control means placed on independent supply circuits for the conduits 45, 46, shown in the drawing in FIG. 5.
  • a first supply circuit 81 is connected to the conduits 45 of the two walls 41, and a second similar circuit 82 simultaneously supplies the conduits 46.
  • Each circuit includes a mixing chamber 83 connected to the supply networks of different inerting gases (for example argon, nitrogen, etc.) by adjustable valves 84 to adjust the composition of the mixture formed in the chamber, and a distribution circuit successively comprising: a remote-controlled all-or-nothing valve 85, a pressure gauge 86 and a thermometer 87, a gas heater 88, a second set of pressure gauges 89 and thermometer 90, a flow meter 91, a regulator 92 for regulating the gas pressure or gas mixture in the conduits 45, and a pressure gauge 93.
  • a remote-controlled all-or-nothing valve 85 a pressure gauge 86 and a thermometer 87, a gas heater 88, a second set of pressure gauges 89 and thermometer 90, a flow meter 91, a regulator 92 for regulating the gas pressure or gas mixture in the conduits 45, and a pressure gauge 93.
  • the two circuits 81 and 82 can be completed by a third similar circuit for direct injection of inerting gas into the cowling.
