Definitions

  • the subject of the present invention is a cylinder for a device for direct continuous casting of thin strips of liquid metal between two cylinders, or on a single cylinder, according to the preamble of claim 1.
  • these cylinders comprise a cylindrical core coated with a ferrule generally made of copper and are cooled by circulation of a cooling fluid, such as water, in channels formed between the ferrule and the core or in the ferrule.
  • a cooling fluid such as water
  • the object of the invention is to produce cylinders which make it possible to eliminate this drawback and therefore to obtain cast products with a profile of satisfactory thickness.
  • the cylinder comprises, around the first ferrule, a second ferrule forming with the first two superimposed cylindrical layers, and chosen from materials such that the internal ferrule has a higher coefficient of expansion than that of the external ferrule , in contact with the liquid metal.
  • the expansion coefficients and therefore the corresponding materials are chosen so that the differential expansion between the two materials compensates for the tendency that the double ferrule thus produced would have to bulge, in particular at the center of the centers of the cylinders.
  • the internal ferrule can for example be made of copper while the external ferrule is made of steel, these two ferrules being welded to one another.
  • Figure 1 is a perspective view of a cylinder having a double ferrule according to the invention and intended for a device for continuous casting of thin strips of metal.
  • Figure 2 is a partial axial sectional view of the cylinder of Fig.1.
  • the cylinder 1 shown in the drawings is intended for a device for the manufacture of thin metal strips by direct continuous casting of liquid metal such as steel, between two similar cylinders 1. Such a device is well known in itself and has therefore not been shown.
  • the cylinder 1, of axis XX consists of an internal cylindrical core 2 and two annular rings 3, 4 superimposed, which surround the internal core 2, in which are formed cooling channels 5 where can circulate water.
  • the two superimposed layers 3 and 4 are chosen from materials such that the internal shell 3 has a higher coefficient of thermal expansion than that of the external shell 4 in contact with the liquid metal.
  • the two ferrules 3 and 4 are linked to each other, for example by welding, by loading one of the materials on the other, or by electrolytic deposition.
  • the internal ferrule 3 is made of copper and the external ferrule 4 made of steel, copper having in fact a coefficient of expansion greater than that of steel.
  • the thicknesses of the two layers 3 and 4 are adjusted as a function of the expansion coefficients of the materials chosen.
  • the differential expansion between the two materials of layers 3 and 4 compensates for the tendency of the double ferrule to bulge, especially at the center distance of the two cylinders of the device.
  • the internal ferrule 3 is preferably made of copper and has a thickness of 5 to 30mm.
  • the outer shell can be made of steel, nickel or chrome, and have a thickness of 1 to 10mm.
  • the crown of the cylinder is 0.3mm, whereas if the shell is entirely in copper, the bulge is about 1mm.
  • coating a material having a lower coefficient of expansion and better thermal conductivity, such as chromium.
  • the invention is not limited to an arrangement of the cooling channels 5 under the double ferrule (3, 4), but that these channels can be drilled in the internal ferrule 3.
  • the thickness of the copper ferrule mentioned above corresponds to the case where the cooling channels are provided under this ferrule.
  • the thickness considered is the radial distance between these channels and the internal ferrule-external ferrule interface, because in this case, the thickness of internal ferrule situated between the channels and the core is kept at low temperature and has little influence on the effect of differential expansion.
