Definitions

  • the present invention relates to a device for cooling metal products, in particular beams, during rolling.
  • the boxes must be able to match the shape of the surface of the beam so as to create a film of water with a thickness of 10 to 20 mm.
  • the implementation of this process requires complex and expensive equipment.
  • the numerous processing possibilities offered by this device cannot be fully exploited in the case of rolling trains on which pass products of very different sections.
  • the object of the present invention is to propose a simple and effective device which avoids the disadvantages mentioned above and which is capable of subjecting rolled products of the same type to a quenching operation.
  • the section of the beam can frequently change during rolling, provision has been made for adaptable boxes capable of guaranteeing the consistency of the thickness of the water film.
  • the suspension of the upper boxes has a quick opening system to allow a beam to pass through, the section of which has been accidentally deformed, without there being any damage.
  • FIGS. 1 and 2 a distinction is made between the beam 1 moving on the train of rollers 2 in the direction indicated by the arrow F as well as the cooling boxes 3, 4 and 5 provided with substantially cylindrical and equidistant orifices on the faces in look of the product to be cooled. All the lines of orifices are slightly inclined with respect to the rolling axis in order to guarantee regular cooling around the contour of the laminated profiles.
  • the external cooling boxes 5 are mounted on the outlet guides 6, movable in the direction perpendicular to the direction of movement of the beams. The height of these boxes must exceed the upper edge of the beam 1. It follows that the water overflows into the upper chamber of the beam cooled by the upper boxes 4.
  • the spacing of these boxes 4 is adjustable by the nuts 7. During operation, the spacing of the boxes is maintained by the springs 8 giving the boxes a certain flexibility to counter possible movements of the section in the transverse direction.
  • An adjustable stop 11 actuated by a motor 12 rests against a cleat 14 integral with the arm 10 and allows precise height adjustment of the upper boxes 4.
  • the suspension arms 10 pivoting in the direction of movement of the beams provide a certain flexibility in the longitudinal direction, necessary to avoid damage to the boxes 4 due to possible defects in the core and the wings of the beam, as p. ex. ripples or puffs.
  • the boxes can in particular be completely removed by actuation of the piston 9.
  • the lower cooling boxes 3 are pre-assembled outside the train, the spacing being adjusted by spacers 13 chosen as a function of the height of the beam to be laminated. Having the shape and function of a guide, the lower boxes are rigid and have the solidity necessary to withstand shocks caused by inadvertent contact with the product. The installation of the lower boxes is done when changing the rolling rolls, to move from one profile to another.
  • the beam is centered on the roller table by three pairs of centering rollers, which are located at the inlet, in the middle and at the outlet of the cooling ramp.
  • the length of a ramp will preferably be limited to 8 m.
  • the running speeds vary between 0.5 and 4 m / s for H beams, the dimensions of which are included in the standard range of European and American beams with web height of 200 at 1000 mm.
  • the upper chamber of the beam is filled with water.
  • the uniform film of water with a thickness of 10 to 20 mm is interrupted between the two boxes 4 where a water column is formed with a height equal to half the width of the wing of the beam.
  • the boxes 4 can be assembled by spacers identical to those which maintain the distance between the lower boxes 3.
  • the spacers between the boxes can be dispensed with. cooling, the homogeneity of the cooling not being affected by the accumulation of water in the upper chamber.
  • the upper chamber is closed using a barrier element placed at the outlet of the cooling ramp .
  • a barrier element placed at the outlet of the cooling ramp .
  • Such an element which essentially comprises a closed metal box 34 to which is fixed a flattened box 32 provided with numerous holes 33, is shown in FIG. 3.
  • the suspension system leading to the closed box 34, just like supply ducts d air leading to the flattened box 32 have not been shown.
  • air jets In operation, air jets, inclined in the opposite direction to the direction of travel of the beam, exit under high pressure from the holes 33 and are projected against the beam 1. They act in a way as a pneumatic seal and prevent the cooling water to be driven by the beam.
  • the barrier element must obviously be changed for each type of beam. It is obvious that instead of using air to prevent water from being entrained by the beams, it is possible to consider using other inexpensive fluids. Similarly, instead of providing the metal box 32 with holes, one can think of using a multitude of ejection nozzles, giving the jets the most diverse shapes.
