Definitions

  • the invention relates to an installation for cooling long moving products. It relates more particularly to the entrainment of these products during the cooling to which they are subjected after rolling.
  • German patent application DOS No. 2,539,422 is an installation comprising a line of tubular boxes filled with a coolant through which the product to be cooled passes, the boxes being separated from each other by rollers ensuring the product drive.
  • the current trend is to use more efficient cooling devices consisting essentially of a cooling tube, in which the product is not immersed in a static body of water, but surrounded by a blade. water circulating at high speed parallel to the product.
  • the tube is equipped at one end with a water supply head and at the other with a separator to dissociate the product from its liquid envelope. It is thus possible, for products of relatively large diameter, made of weldable low carbon steel, to follow a cooling law fast enough for the mechanical characteristics obtained to make subsequent work hardening unnecessary.
  • the object of the present invention is precisely to remedy this drawback. More specifically, the invention proposes to provide a solution to the problem which consists in being able to equip a water-blade cooling tube with a device for driving the product to be cooled without, however, adversely affecting the movement of the product, nor to the circulation of the water layer, or to the tightness of the assembly.
  • the subject of the invention is an installation for cooling long products in movement surrounded by a cooling liquid envelope comprising a cooling tube provided at one of its ends with a coolant supply head. and, at the other end, a separator for dissociating the product from its liquid envelope, installation in which the cooling tube is equipped with at least one roller drive device for the product, characterized in that the roller is mounted horizontally in a box provided, on the one hand, with two connections connected to the cooling tube and respectively defining an inlet and an outlet of the box to allow the passage of the product in a straight line through this box and, on the other hand, a cover whose inner face shaped as a semi-circular channel defines with the roller a passage for the product and the liquid envelope which surrounds it, and in that, relative to the s ens of movement of said product, the inlet connector has a cylindrical passage followed by a convergent and the outlet connector has a cylindrical passage preceded by a convergent.
  • the drive device characteristic of the invention essentially consists of a roller 1 placed inside a sealed box 2 and rotated by a motor 3.
  • the box consists of a bottom 4, two walls side 5 and 6 and a cover 7.
  • the roller 1 is mounted on an axis 8 carried by two rolling bearings 9 and 10 disposed respectively in the side walls 5 and 6.
  • the end of the axis carried by the bearing 10 crosses the wall 6 and is connected to the motor 3 which ensures the rotation of the assembly, at the chosen speed, in the direction of travel of the product.
  • the latter has not been shown, so as not to overload the figures, but its direction of travel is indicated by an arrow in FIG. 2.
  • the other end of the axis 8 is protected by a cover 11 fixed to the wall 5 by screws such as 12.
  • Two pieces of elastic material 13 and 14 respectively provide a flexible connection between the axis 8 and the walls 5 and 6.
  • the cover 7 has a semi-cylindrical recess 15 intended to serve as a passage for the product.
  • This cover 7 is connected to the cooling tube, as can be seen in FIG. 2, by two tubular ends 16 and 17.
  • the end piece 16 In the direction of travel of the product, the end piece 16 has a first cylindrical passage extended by a converging part and the end piece 17 has a cylindrical passage preceded by a converging part in order to facilitate the introduction and the exit of the product into the device.
  • the cover 7 is fixed to the side walls by screws such as 18.
  • An annular groove 19 is formed on the periphery of the roller 1 in order to ensure better contact with the product.
  • the latter accompanied by its liquid envelope therefore penetrates through the nozzle 16, comes into contact with the roller and exits through the nozzle 17 at higher speed.
  • the passage delimited by the recess 15 and the groove 19 is less than the inside diameter of the cooling tube to allow the device to perform its centering function.
  • Part of the liquid envelope therefore passes through the space delimited by the roller 1 and the bottom 4 of the box. O-rings are provided wherever their presence is necessary to ensure the tightness of the assembly.
  • the roller can in particular be of elliptical section in order to give the product a lateral movement to destabilize the vapor films which may possibly form.
  • provision can be made to have blades at the ends of the groove in order to prevent water from stagnating at the bottom of the box.
  • the number and position of the devices according to the invention is not limited: they can replace a single centering device, this may be sufficient in certain cases to keep the speed constant, some or all of these devices.
  • the rollers can be placed under the product as in the example described, in staggered rows, one below followed by another above, in order to obtain a straightening effect. Two superimposed rollers can be placed in the same box, the product passing between the two. Finally, some or all of the rollers are not necessarily driven by a motor, their passive role then being identical to that played by the rollers with which conventional cooling installations are provided.
