Definitions

  • the invention relates to a device for the hydromechanical descaling of continuously cast slabs and / or hot-rolled metal strip, in particular steel, comprising in each case one band side, in the belt running direction behind each other and laterally staggered arranged water spray nozzles for spraying high-pressure water jets on the two-sided tape surfaces, of which
  • the rows of nozzles associated with the upper side of the band together with collecting channels can each be pivoted about an axis and can be adjusted in height relative to the band upper side in accordance with the signal of a measuring device.
  • a known descaling device for descaling with high-pressure water is described in DE 43 28 303 A1.
  • a series of rotating nozzle heads each having four circumferentially spaced nozzles for spraying the high pressure water on a bar immovable and arranged transversely to the direction of movement of the conveyed below rolled bar at such a distance that bulges and bumps on the nozzle device do not lead to a collision along conveyed rolling stock.
  • this distance is comparatively large. This reduces the jet pressure of the high-pressure water at the rolling stock, which can only be compensated by increasing the water pressure or the amount of water and requires a large amount of energy.
  • German patent application P 198 17 002.5 which applies a fluid to the surface of the semifinished product moved relative to the nozzle device under high pressure and optionally comprises a device for removing the scale , with which a more uniform Entzo matterspralltik, the so-called Impact, and thus a more uniform descaling over the bandwidth and length can be achieved as in conventional devices.
  • a device for descaling semifinished products has been proposed by German patent application P 198 17 002.5, which applies a fluid to the surface of the semifinished product moved relative to the nozzle device under high pressure and optionally comprises a device for removing the scale , with which a more uniform Entzo mecanicspralldruck, the so-called Impact, and thus a more uniform descaling over the bandwidth and length can be achieved as in conventional devices.
  • means are provided for the direct detection of the strip profile, wherein depending on this, the nozzle device and / or the tinder removal device are each individually height-adjustable.
  • the document EP 0 360 480 B1 describes a descaling device for a material strip with a device for bending the strip by at least one bending roll at one point, and a water spraying device which sprays the water at a descaling point slightly spaced from the bending point in the strip running direction. Due to the bending of the band, the scale should be broken or detached from the surface of the band, whereby the descaling even at a comparatively lower water pressure can be performed.
  • WO 97/117 97 describes a device for descaling semi-finished products.
  • a nozzle device with a vertical component on the surface of the semi-finished product is arranged to be movable by means of a drive and there is provided a displacement sensor for detecting the distance of the nozzle device from the surface.
  • a control device for influencing the drive is provided as a function of an output signal of the displacement transducer for keeping the distance constant.
  • the document DE 29 22 701 C2 discloses a device for descaling hot rolled metal strip in a strip rolling line in which the strip is cold rolled after descaling in downstream rolling stands.
  • Each nozzle row parallel to the belt plane is pivotable by means of a holder about an axis perpendicular to the belt plane and the belt longitudinal axis at an adjustable angle ⁇ to the belt longitudinal center axis and is maintained at an inclination angle, the so-called jet angle ⁇ of the nozzle axes to the belt surface of less than 90 °.
  • the holder of a nozzle row bearing nozzle bearing block has a pivoting device for varying the angle of inclination or Strahlaufterrorismwinkels ⁇ of the nozzle axes to the strip surface while maintaining intersections of the nozzle axes with the band level.
  • the present invention seeks to provide a device for hydromechanical descaling mentioned in the preamble of claim 1, which compared to the prior art to an extremely effective Function unit is developed further and has the significant advantages in the event of an accident.
  • the device according to the characterizing features of claim 1, according to which the water collecting channels are independent of the water spray nozzles pivotable about a pivot point and height adjustable with respect to the metal band and are independently evasive and then the nozzle rows receiving spray bars the top of the tape a lever arm around the pivot point of the water collecting channels freely pivotable and thus height adjustable within limits and are arranged automatically evasive.
  • the nozzle rows are arranged together with the receiving them spray bar and collapsible collecting rings on the top of the tape within a nozzle rows and spray bars with their pivot axes receiving hood, the hood of four corners the upper driver rollers respectively associated lifting cylinders worn.
  • each one band side 3, 4 associated in the tape running direction one behind the other and laterally offset from each other in series arranged water spray nozzles 1, 1 'for spraying high-pressure water jets 10, 10' with about 600 bar on the two-sided tape surfaces.
  • the rows of nozzles 1 associated with the upper side 3 of the band are pivotable together with collecting channels 2 in each case around an axis parallel to the strip surface and perpendicular to the longitudinal plane of the strip and are adjustable in height relative to the strip upper side 3 in accordance with the signal of a measuring device (not shown).
  • the rows of nozzles 1 are arranged together with the receiving them spray bar 5 and cooperating collecting channels 2 on the upper side of the tape 3 within this with their pivot axes receiving hood 6.
  • the hood 6 is supported by four cornering the upper drive rollers 8 each associated lifting cylinders 7.
  • the interior of the hood 6 is relatively generously sized in height, width and length to avoid interference edges and Verwirbelungszonen for water and scale.
  • the hood 6 can be decoupled by means of a releasable connection with the driver rollers 8.
  • the hood 6 is shown in the raised position, wherein after disconnecting the driver roller 8 of left-side Anstellzylindern 7, the dashed line driver roller 8 'further cooperates with the counter-roller below the belt 20 and the belt can be pulled.
  • the inventive design of the scale washer is designed so that the upper part with hood 6, lifting cylinders 7, drive rollers 8 and pipe connections for the purpose of repair and / or maintenance is preferably lifted by crane.
  • the spray bars 5 'of the lower side 4 of the band can be lowered independently of the spray bars 5 of the band upper side 3.
  • the belt 20 runs, as is generally customary, on drivable transport rollers of the roller table 14.
  • the water collecting channels 2 are pivotable against a pivot point 9, independently of the water spraying nozzles 1, and are automatically height-adjustable with respect to the belt 20 with their catching mouth 12. This results in the advantage that when undisturbed operating condition, the jaw 12 of the gutter 2 on the belt surface 3 of the belt 20 slid loosely along slides, but when occurring, for example, a bent-head band head (Fig. 1 left side) automatically by pivoting about the fulcrum. 9 of the Tape surface is lifted. This will prevent disasters in the scale washer with great advantage.
  • An embodiment of the device provides, as shown in Figure 2, that the hood 6 together with the spray bar 5 and collecting gutters 2 by means of the lifting cylinder 7 is comparatively high for releasing a free passage from the belt 20 can be raised.
  • the design according to the invention realizes a device for the hydromechanical descaling of continuously cast slabs and / or hot-rolled metal strip, an extremely compact functional unit with significantly reduced susceptibility to interference.
