Definitions

  • the invention relates to a device for cooling flat rolling stock, in particular rolled strip, by means of laminar cooling water jets, distribution pipes being arranged transversely above or below the rolling stock pass, the walls of which are provided with bores over the maximum rolling stock width and are connected to the guide tubes.
  • the distributor pipes are connected at one end to a water supply line.
  • the outlet pipes are inserted in the upper openings of the distributor pipes and are guided downwards in an arc on both sides.
  • the range of effects resulting from the number and division of the guide tubes becomes designed according to the maximum rolling stock width. This has the disadvantage that with narrow rolling stock widths, a considerable part of the coolant flows uselessly onto the free side sections of the roller table.
  • the coolant wastage should be avoided with changing rolling stock widths.
  • the task is to create a cooling device whose range of action can be adjusted quickly and precisely to all rolling stock widths using simple means.
  • distributor pipes are provided with a water connection approximately in the middle of their jacket and pistons sealingly guided on both sides within the pipe jacket are adjustable in opposite directions.
  • the length of the water column within the distribution pipes is determined by adjusting the pistons. In this way, the exposure of water from guide tube to guide tube can be set exactly to the respective rolling stock width and the cooling water consumption can be reduced.
  • the pistons can advantageously be adjustable by means of a spindle with a right-hand and Ling thread that is guided centrally in outer tube covers.
  • the pistons are guided by means of bores on guide rods fastened in the tube covers and running parallel to the spindle.
  • hot rolled strips 1 are conveyed on an outfeed roller table 2 and cooled with water over a defined area on the top and bottom.
  • the cooling water is supplied through upper and lower water pipes 3, 4 which are attached to vertical supports 5.
  • Each upper water pipe 3 is connected to a distributor pipe 7 arranged transversely above the roller table 2 and laterally closed by cover 6 in the middle thereof.
  • the distributor pipe 7 is provided on the upper side with a plurality of guide pipes 8, which run downwards in an arc.
  • the distributor pipe 10 is provided on its upper side with straight guide pipes 11 directed towards the underside of the band.
  • Each lower water pipe 4 is connected to a distributor pipe 10 arranged below the roller table 2 and laterally closed by cover 9 in the middle thereof.
  • the cooling water flowing in through a nozzle 12 fills the distributor pipe 7 or 10, rises evenly through bores 13 on the upper side thereof into the guide pipes 8 or 11 and flows onto the rolled strip 1.
  • pistons 15, 16, each sealingly guided in the distributor tube 7 or 10 are guided on a right-hand or left-hand thread of a hand or motor-driven spindle 14 mounted in the covers 6 or 9.
  • a rod 17 fastened in the covers 6 and 9 runs through the distributor pipe 7 and 10, which penetrates the pistons 15, 16 as a means of preventing rotation.
  • Rotation of the spindle 14 moves the pistons 15, 16 in opposite directions, as a result of which the width of the water column located in the distributor pipe 7 or 10 between the pistons 15, 16 is changed.
  • the bores 13 located in the distributor pipes 7 and 10 can be separated from the water supply one after the other in order to adapt to narrower bands.
  • the invention is not restricted to the exemplary embodiment shown.
