Definitions

  • the opening in the front face of the shroud is not mechanically or physically closed or covered but an inert gas curtain prevents ambient air from entering the shroud. Gas is blown parallel to the plane of the opening and/or in a direction from inside the shroud to the outside of the shroud forming a gas flow out of the shroud. Thereby, ambient air is pushed away from the opening and the ingress of humid air into the shroud is prevented.
  • the gas flow 9 is redirected to flow parallel to the plane of the opening of the shroud 6 or in a direction from inside the shroud to outside the shroud.
  • a separate gas supply system for forming the gas barrier.
  • Such a separate gas supply system may comprise a tube around the opening of the shroud 6 connected to a gas supply line and provided with a number of apertures for gas to pass through and form a gas curtain.
  • the gas flow through duct 11 is stopped or at least reduced in order to avoid that ambient air from the surroundings is sucked into the shroud 6.
  • the pressure inside the shroud 6 should preferably be close to the pressure of the ambient air. If the pressure is too high the cold gas from inside the shroud will escape, if it is too low then air will get sucked in.
  • the adjusting mechanism guarantees that the inner space of the shroud 6 is always sealed to the surrounding atmosphere:
  • the purge gas flowing through the outer pocket 26 has a double function: First, it insulates the shroud 6 and keeps the outer wall of the outer part 21 warm to avoid condensation on the outer part 21. Second, in the working configuration the purge gas leaving the outer pocket 26 at the edge 27 works as a gas seal between the shroud 6 and the work roll 1.
  • a purge gas 37 is supplied to gas port 36 and flows through aperture 35 and opening 34 into the passage 32.
  • the purge gas 37 continues to flow through the passage 32 and leaves it at the end where the two shields 22a, 22b abut.
  • the purge gas 37 keeps the outer surface of the shields 22a, 22b warm and works as a gas seal between the two shields 22a, 22b.
  • the shields 22a, 22b are also double-walled forming a passage for a purge gas between the walls of the double-wall structure.
  • the gas port 39 for the purge gas is directly connected to the shields 22a, 22b.
