Definitions

  • the invention relates to a method and a device for cooling hot-rolled plates and strips made of metal, in particular of aluminum or an aluminum alloy, a hot-rolled strip being cut into plates or strips immediately after it emerges from a hot rolling mill.
  • a hot rolling strip usually has a temperature in the range between approximately 300 and 500 ° C. when it exits a hot rolling mill. To produce plates, these are cut immediately after the hot-rolled strip emerges from the hot rolling mill. Since there is no suitable sealing material for vacuum suction cups that can be used at temperatures above 300 ° C, the hot plates must be removed from the roller table for stacking with gripping tools. This handling of the plates is labor-intensive on the one hand, and on the other hand unwanted traces of the gripping tools can remain on the surface of the plates. A rapid cooling of the plates could in principle take place through the roller emulsion when carrying out empty runs without stitch acceptance. The resulting large temperature differences on the hot rolled strip would lead to unacceptable deviations from the flatness of the plates.
  • EP-A-0 578 607 discloses an inline method for cooling profiles emerging from an extrusion press, in which the spray nozzles known from EP-A-0 343 103 are installed in modules.
  • the inventors have set themselves the task of creating a method and a device of the type mentioned at the outset, with which plates and strips can be checked and cooled as quickly as possible to a temperature of at most about 250 ° C. without the plates Flatness deviations occur.
  • the plates or strips continuously pass through a cooling station immediately after being cut to length, and water is directly applied to them in the flat jet nozzles, the water jet emerging from the flat jet nozzles essentially directed towards the plate or strip surface Forms a plane and the water jet is deflected periodically by air or water jets immediately after it emerges from the flat jet nozzle in such a way that the water jet striking the plate or strip surface performs a wiping movement.
  • the water jet emerging from the flat jet nozzle is preferably pivoted through an angle in a range between 30 and 120 °.
  • the distance from the outlet opening of the flat jet nozzle to the plate or strip surface is preferably set to approximately 100 to 200 mm.
  • the impact surface of the water jet on the plate or strip surface preferably has a width of approximately 5 to 10 mm, the length: width ratio being between approximately 5: 1 and 100: 1.
  • a frequency for the wiping movement which is suitable for the method according to the invention is between approximately 0.1 and 20 Hz.
  • the wiping movement is preferably carried out at a frequency of approximately 0.5 to 2 Hz.
  • the flat jet nozzles are arranged on nozzle strips running in the running direction of the plates or strips.
  • the nozzle strips preferably comprise a longitudinal water channel and two longitudinal air channels, branch channels branching from the water channel to the flat jet nozzles and the air channels ending in air gaps directed towards the nozzle outlet openings.
  • the nozzle strips can be separated into water-feedable modules be divided or built up from such modules.
  • the nozzle strips or modules have a preferably extruded base body, in which the flat jet nozzles are interchangeably inserted.
  • covers which form an air chamber, are preferably placed on the base body with an air gap directed at the nozzle outlet openings, and the air chambers are connected to the air channels via connecting channels.
  • a hot rolling strip 12 emerges from a hot rolling mill 10, which is cut into plates 16 by means of scissors or saw 14 and is moved via a roller table 18 in the transport direction x through a cooling station 20.
  • the in the Cooling station 20 cooled plates 16 are temporarily stored as a stack 22 until further processing.
  • a cut hot rolling strip 12a passes through the cooling station 20, which is arranged here in front of the tandem mill stand 21 of a finishing train.
  • a reversing stand could also be used.
  • lower and upper nozzle strips 24 are arranged inside the cooling station 20 in the plate or tape transport direction x. 3 and 4, modules 26 with three flat jet nozzles 52 are shown.
  • the nozzle outlet openings 53 visible from the flat jet nozzles 52 which are at a distance of, for example, 150 mm from the surface 32 of the plate 16 or the band 12a, are arranged at regular intervals of, for example, 100 to 200 mm.
  • Covers 34, 36 for air chambers 38, 40 are visible on both sides adjacent to the nozzle outlet openings 52.
  • Additional water nozzles 60 are optionally provided. These water nozzles 60 are then switched on when the cooling effect of the flat jet nozzles 52 is inadequate in the case of thicker plates 16 or belts 12a at the predetermined transport speed.
  • the modules 26 With their end faces 27 directly adjacent to one another or lined up at a short distance from one another, the modules 26 form the lower and upper nozzle strips 24. Each module 26 can be fed separately with water and air. As can be seen in particular from FIG. 5, the module 26 has a preferably extruded base body 42 with a longitudinal central water channel 46 and longitudinal air channels 48, 50 arranged on both sides of the water channel 46.
  • the air channels 48, 50 are connected to air chambers 38, 40 via connecting channels 62, 64.
  • These air chambers 38, 40 are formed by covers 34, 36 screwed to the base body 42. Between the cover 34, 36 and the by about 45 ° An inclined surface of the base body 42 is an air gap 54, 56 directed toward the nozzle outlet opening 53.
  • the water channel 46 is connected to the flat jet nozzles 52 via branch channels 58. If required, the additional water nozzles 60 are supplied via a further water channel, not shown in the drawing.
  • the air pressure ratios for the two air jets A, B as a function of time t are shown in FIGS. 6 and 7.
  • the air pressure p is set in each case in the corresponding air duct 48 or 50.
  • the water jet W is first deflected from its normal position by the first air jet A to the maximum and returned to the normal position. Now the water jet W is deflected by the second air jet B in the other direction to the maximum deflection and then back to the normal position.
  • This mutual periodic deflection with a period T takes place, for example, at a frequency of approximately 1 Hz.
  • the air jets A and B for deflecting the water jet W can in principle be replaced by water jets, in which case the total amount of water composed of the water jet W and the deflecting water jets is preferably kept constant.
  • the wiping movement of the water jet W emerging from the flat jet nozzles 52 runs transversely to the transport direction x of the plates 16 or the belt 12a, successive nozzles each carrying out opposite wiping movements.
  • the length 1 of the impact surface 30 of the water jet W on the surface 32 of the plates 16 or the band 12a is, for example, 200 mm, the width b, for example, 5 mm.
  • the flat jet nozzles 52 are arranged in the nozzle strips 24 or modules 26 in such a way that the impingement surfaces 30 of adjacent water jets W approximately touch during the wiping movement.
