Definitions

  • the subject of the invention is a continuous metal casting machine of the type described in the preamble of claim 1, in particular for the casting of steel in the form of blooms or slabs.
  • a continuous casting machine conventionally comprises a bottomless ingot mold with energetically cooled walls and a secondary cooling corset placed in the extension of the ingot mold.
  • the ingot mold must be made to oscillate while remaining aligned along a casting line and for this purpose it is carried by means connected to an oscillation mechanism and at the same time guided along the casting line.
  • the invention applies in particular to curved casting installations and it is known that, in this case, the cavity of the mold forms an arc of a circle of the same radius as that of the casting line defined by the curved brace, the guide means being arranged so that the oscillation movement occurs in the extension of this curved line.
  • the cooling corset which must be fairly rigid, can be mounted on a chassis in the form of a curved beam parallel to the casting line and, to allow expansion while maintaining alignment with the mold as much as possible, the chassis is mounted often, at its lower part, on a pivot with an axis orthogonal to the median plane of the cast product and rests at its upper part, below the mold, on a fixed slide.
  • the oscillation mechanism is mounted on the chassis of the secondary cooling corset but then the vibrations generated by the oscillation of the mold are transmitted to the cooling corset and can disturb the stability of the alignment of the ingot mold with corset.
  • the subject of the invention is a new arrangement which makes it possible to avoid these drawbacks by ensuring the absorption of vibrations before they are transmitted to the cooling corset or to the nearby casting lines.
  • the metallic support structure is practically eliminated on -which were mounted the oscillation and guide means to replace it with a heavy element which can advantageously be a concrete block and which immediately absorbs the vibrations generated. by oscillation before these are transmitted to the cooling corset or to neighboring lines.
  • FIG 1 there is shown a continuous steel casting installation comprising in a conventional manner, a mold 1 mounted on an oscillating table 2 driven in an oscillating movement by a lever 3 driven by a mechanism 20 mounted on a foundation mass 4.
  • the guide corset is mounted in a chassis 5 in the form of a beam made up, as can be seen in FIG. 3, of two longitudinal members 51 connected together by spacers 52 on which are fixed segments 50 of the guide corset each carrying two pairs of rollers and cooling water spray booms and between which the cast product A is guided along a casting line 10.
  • the beam 5 is articulated at its lower part, around a pivot 53 perpendicular to the plane of the figure, on a support 54 which can be constituted for example by the upper part of the beam supporting the second part of the corset.
  • a support 54 which can be constituted for example by the upper part of the beam supporting the second part of the corset.
  • the beam 5 is guided by an axis 55 sliding along a slide formed on a fixed support 40 and substantially parallel to the casting line.
  • the oscillation lever 3 rotates around an axis 30 in a bearing carried by a support 31 on which is also mounted the bearing of a second axis 32 around which is articulated a connecting rod 33 articulated at its other end on the oscillation table 2 so as to maintain it along the casting line during the oscillations generated by the lever 3 which is also articulated at its end on the oscillating table 2.
  • the lever and the connecting rod 33 consist of two arms placed symmetrically on either side of the median plane of the ingot mold, the oscillating table 2 comprising two lower extensions 21 on which are articulated the ends of the two arms of the lever 3.
  • the support 31 of the bearings of the oscillation lever is mounted neither on the casting floor 11 placed at the level of the ingot mold 1 nor at the upper part of the beam 5, but on the contrary is fixed directly on a platform fixed 6 formed at the upper part of the foundation solid 4 and located substantially at the upper level of the beam 5 for supporting the corset.
  • the foundation block 4 is extended upwards by a part 41 which can rise up to the level of the platform 6, but it is also possible, as shown in the.
  • Figure 1 provide the platform 6 on a chassis 60 in massive mechanically welded construction, which is securely attached to the extension 41 of the concrete block.
  • the chassis 60 can indeed be built very rigidly and yet facilitate the positioning accuracy of the various parts of the machine and in particular of the supports 31.
  • the support 40 of the slide 55 can also be fixed to the chassis 60, as close as possible to the concrete part 41.
  • the arms 62 of the support of the upper element of the corset 56 are fixed directly to the fixed platform 6 of the foundation block 4.
  • the mounting on the same rigid frame 60 of all of the essential components of the machine facilitates the adjustment of the relative positioning of these components and the maintenance of the alignment during casting.
  • the means of oscillation and guiding of the mold as well as the support axes of the corset are therefore fixed on a heavy mass capable of absorbing vibrations.
  • the reciprocal isolation of the lines is carried out in this way.
  • it is possible to improve the 'vibration isolation by a particular study of the upper part 41 of the foundation block and for example, as shown in Figure 3, by mounting each line on an individual foundation block, the neighboring blocks being separated by a space void 42 formed in a vertical plane up to a level. suitable down to ensure isolation.
  • the invention is not limited to the details of the embodiment which has just been described, nor to the type of continuous casting machine which has been retained only by way of example.
  • the invention could be adapted to other types of casting machines and in particular to other types of mechanisms. oscillation and guidance of the mold within the scope of the claims.
