Definitions

  • the present invention relates to a continuous steel casting installation, more particularly intended for the casting of products with square or rectangular section, such as slabs, blooms or billets.
  • the object of the invention is to improve the performance of this type of device in order to be able to increase the reliability of the installation as well as the casting speed.
  • the installation according to the invention makes it possible in particular to obtain, with respect to known devices, better mechanical resistance of the grids, relatively in particular to expansion, as well as a better distribution of the cooling water and a better flow of this after spraying. It is characterized in that it is provided with grids for supporting the cast product each composed of straight prismatic elements fixed on a metal support with high inertia, said support being pierced with orifices intended for the passage of water sprayers, and said prismatic elements being assembled so as to leave free, for each cell, at least two passages for the discharge of cooling water between said cell and at least two adjacent cells.
  • said cells are composed of squares or rectangles standing on one of their points.
  • the mold has its serrated lower edge so as to be able to fit into the serration formed by the upper part of said grid device.
  • the cast product 4 is supported at its exit from the mold by a wear grid 5 whose particular conformation is the main object of the invention, then, after a distance of one to two meters, by conventional rollers 6. Also very conventionally, the cast slab is cooled by spraying water jets from conventional sprayers 7 supplied by water supply ramps 8.
  • the wear grid 5 consists of metallic elements 10 in the shape of a rectangle with a thickness of the order of 5 cm, these straight prismatic elements 10 being made of cast iron or steel and being screwed onto a support plate 9 d neighboring thickness, also of cast iron or steel, possibly cooled by circulation of water although this is not the case in the drawing, and being fixed to the frame of the installation by means not shown.
  • the prismatic elements 10 are assembled three by three as shown in FIG. 2 so as to thus create cells 11 of rectangular section, standing on their point, and leaving on their lower side two passages 12 and 13, allowing the water to cooling to flow down as shown by the arrows in the drawing.
  • the support sheet 9 is pierced with orifices 14, one per cell 11, and leaving room for the projection nozzles 7.
  • the grid of the invention is shaped so that its upper part can be embedded in the serration 3 at the bottom of the mold 1.
  • the grid 5 is arranged so as to leave with the serration 3 a space 15 in which water projectors 16 of rectangular and very elongated shape pass.
