Definitions

  • the invention relates to a device for driving long scrolling products and applies more particularly to the driving of these products during the cooling to which they are subjected after rolling.
  • the current trend is to use more efficient cooling devices consisting essentially of a cooling tube, in which the product is surrounded by a sheet of water circulating at high speed.
  • 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.
  • the invention relates to a device for driving long products in movement surrounded by a liquid envelope. It consists of a roller carried by an axis arranged transversely to the direction of travel of the product, placed inside a sealed box and secured to the side walls of the latter by means allowing its rotation, the box having two orifices to allow the product to pass in a straight line.
  • the box consists of two side walls provided with two rolling bearings, supporting the axis of the roller, a bottom and a cover.
  • the cover has on its internal wall a semi-circular channel for the passage of the product.
  • the semicircular channel is connected upstream, relative to the direction of movement of the product, to a passage pierced with a circular channel followed by a convergent and downstream, relative to the direction of movement of the product, to a passage pierced with a circular channel preceded by a divergent.
  • the roller carries an annular groove at its periphery, the passage of the product taking place between the cover and this groove.
  • the roller can be of circular or elliptical section.
  • the axis of the roller is connected to a drive motor.
  • the invention also relates to an installation for cooling long moving products comprising a cooling tube, where the product circulates and a sheet of water enveloping the latter, said tube being equipped at its two ends respectively with a head d water supply and a water-product separator, a drive device at least as explained above being arranged in the cooling tube.
  • the drive device 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 side walls 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 II fixed on 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 seal 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.
