Definitions

  • the subject of the present invention is a cylinder for a device for continuous casting of thin strips of metal on a cylinder or between two parallel and rotary cylinders, of the type comprising a central block coated with a hoop.
  • the cylinders usually used until now have an unheated central zone, cooling channels being provided in the hoop or between the hoop and the surface of the central zone, which is for example made of steel, while the hoop is copper and in contact with the liquid metal during casting.
  • the object of the invention is therefore to produce a cylinder in which this drawback is eliminated.
  • the cylinder for a device for the continuous casting of thin strips of metal is characterized in that its central block is chosen from a material with a high coefficient of expansion. and is provided with heating means capable of causing a radial expansion of the block of the same value as that of the hoop.
  • the central block can thus be made of aluminum and heated by electrical resistances embedded in the block, the heating of which is suitably adjusted in order, taking into account the coefficient of expansion of the material constituting the block, to cause radial expansion. of the latter practically equal to that undergone by the hoop during casting. Therefore, any differential expansion disappears and the mechanical strength of the hoop on the block is ensured.
  • the cylinder 1 shown in Fig.1 is intended for a device, not shown, known per se, for the continuous casting of thin strips of metal between two such cylinders, parallel and rotary.
  • This cylinder 1 comprises a massive central block 2 coated with a hoop 3 in contact with the liquid metal bath during casting, channels 4 for cooling the hoop 3 being formed between the latter and the block 2.
  • the solid central block 2 may include an axial cylindrical recess 5 and is chosen from a material with a high coefficient of expansion, such as aluminum.
  • the solid block 2 is internally provided with electrical heating resistors 6 arranged in concentric channels 7 arranged in the block 2, at a suitable distance from its axis.
  • the intensity of the current passing through the resistors 6 is adjusted so as to cause a more radial than axial expansion of the material constituting the block 2, and which, taking into account its coefficient of expansion and that of the material constituting the hoop 3 (for example copper), causes a radial expansion of the block 2 equal to that of the hoop 3, caused by heating in contact with the cast liquid metal. Under these conditions, the latter can be maintained during the pouring of the liquid metal in mechanical contact over its entire surface with the block 2 without it being necessary to clamp it as has been proposed so far.
  • the heating and cooling of the block 2 are regulated, in transient modes, in particular at the start of casting, according to the same thermal kinetics as that of the hoop 3, according to cycles corresponding to a cylinder revolution, that is to say a few seconds.
  • the heating can in particular be regulated as a function of the pressure force between the hoop and the central block, measured for example by strain gauges.
  • the central block 8 of the cylinder 9 consists of an axial core 11 and an outer casing 12, coated with the hoop 3.
  • the casing 12 is connected to the core 11 by a set of radial expansion bars 13, equipped with heating means, for example induction coils 14 wrapped around the bars 13.
  • the coils 14 are connected in a manner known per se, at the ends of the cylinder 9, to a supply circuit not shown.
  • the material constituting the central core 11, the radial bars 13 and the casing 12 is chosen with a sufficiently high coefficient of expansion so that a minimum heating by induction by the coils 14 causes a maximum radial elongation of the bars 13 and a radial expansion corresponding envelope 12.
  • the material of the central block 8 may be aluminum.
