Definitions

  • the present invention relates to an adjustment device during casting of a mold for continuous casting of products with rectangular section according to the preamble of claim 1. (see: JP-U-52-30336).
  • Adjustable ingot molds which comprise a device, generally with return cylinders, making it possible to move the long sides very slightly apart while the desired adjustment of the short sides is carried out in order to modify the width of the slab. It is indeed necessary to allow the short sides to slide between the long sides, which normally trap them very tightly, so as to avoid any risk of jamming when adjusting the width.
  • the device of the invention does not have this kind of drawbacks. It is of the type comprising clamping devices making it possible to release, during the adjustment of the short sides to the desired width, the pressure exerted on the long sides, its characteristics being defined in the characterizing part of claim 1.
  • the mold has a frame 1 which is fixed a large side 2.
  • the second large side 3, stiffened by a plate 4, is movable.
  • the short sides 7 can move to modify the width of the cast product, thanks to conventional mechanisms 8 which have been shown diagrammatically in the form of screws.
  • two upper clamping devices 9 and two lower clamping devices 10 allow the large side 3 to be loosened and tightened against the short sides 7.
  • the tightening is carried out by elastic stacks 5, while that the loosening is controlled for the upper clamping devices 9 by two hydraulic cylinders 6, and for the lower clamping devices 10 by hydraulic cylinders 11.
  • the hydraulic circuits for controlling the jacks 6 on the one hand, and the jacks 11 on the other hand, are of separate settings. It is thus possible to adjust the loosening of the long side 3 in order to avoid, while moving the short sides 7 during casting, any seizure of these, despite the ferrostatic pressure and phenomena of thermal origin.
  • FIG. 3 shows the hydraulic circuit allowing separate adjustments for the upper cylinders 6 and the lower cylinders 11.
  • the pipes 12 supplying the jacks 6 are combined in a single pipe 13, and the pipes 14 supplying the jacks 11 are combined in a single pipe 15.
  • the pipes 13 and 15 each lead to valves of pressure adjustment, respectively 16 and 17, then they are combined in a single pipe 18 on which the hydraulic pressure is applied or released using a conventional solenoid valve 19.
  • the devices 16 and 17 will be adjusted so that the contact pressure between large and small sides has a given uniform value. We can similarly adjust these pressures so that this contact pressure remains constant for different spacings of the short sides.
