Definitions

  • the invention relates to a device for hydromechanical descaling continuously cast slabs and / or hot-rolled metal strip, in particular made of steel, each associated with a hinge side, in the direction of belt travel water spray nozzles arranged one behind the other and laterally offset from one another for spraying high-pressure water jets onto the belt surfaces on both sides, of which the rows of nozzles assigned to the upper side of the strip come together with gutters each pivotable about an axis and in accordance with the Signals of a measuring device are adjustable in height relative to the top of the belt are.
  • a known descaling device for descaling with high pressure water is in DE 43 28 303 A1.
  • this distance is comparatively large. This reduces the jet pressure of the high pressure water on the rolling stock, which can only be increased the water pressure or the amount of water can be compensated and one requires large amounts of energy.
  • Document EP 0 360 480 B1 describes a descaling device for a Material band with a device for bending the band by at least one Bending roller at one point, and a water spray device that the water at a distance slightly from the bending point in the tape running direction Descaling point sprayed on.
  • Document WO 97/117 97 describes a device for descaling Semi-finished products.
  • a nozzle device with a vertical component is over the surface of the semi-finished product is movably arranged by means of a drive and it is a displacement sensor for detecting the distance of the nozzle device from provided the surface.
  • a control device for influencing of the drive depending on an output signal from the displacement sensor Keeping the distance constant is provided.
  • Document DE 29 22 701 C2 discloses a device for descaling hot-rolled metal strip in a strip mill, in which the strip after the Descaling is cold rolled in downstream rolling stands. They are each assigned to a hinge side, one behind the other in the direction of the hinge, but offset rows of nozzles arranged to each other for the blasting of descaling agents intended. Each row of nozzles parallel to the belt level is by means of a holder about an axis perpendicular to the belt plane and to the belt longitudinal center axis an adjustable angle ⁇ to the longitudinal axis of the band and is pivotable with an angle of inclination, the so-called jet impact angle ⁇ of the nozzle axes held at less than 90 ° to the belt surface.
  • the bracket of a row of nozzles stored nozzle bearing block has a swivel device for changing the angle of inclination or jet impact angle ⁇ of the nozzle axes Belt surface while maintaining intersection points of the nozzle axes with the band level.
  • the object of the invention is a device for hydromechanical descaling mentioned in the preamble of claim 1 Specify type that is extremely effective compared to the prior art Functional unit is further developed and the significant advantages in the case has an accident.
  • the problem is solved with the device according to the characteristic Features of claim 1, according to which the water collecting channels the tape running direction by one regardless of the water spray nozzles Swivel point pivotable and height adjustable compared to the metal band are and are independently evasive and after which the receiving the rows of nozzles Spray bar on the top of the belt with a lever arm around the pivot point the water gutter can be swiveled freely and is therefore height adjustable within limits and are arranged to be automatically evasive. With these measures the risk of damage with the metal band is significantly reduced.
  • the rows of nozzles together with the spray bars that receive them and can interact with them Collecting rings on the top of the belt within one of the rows of nozzles and spray bars arranged with their swivel axis receiving hood are, the hood of four corner the top driver rollers each associated lifting cylinder is worn.
  • the spraying and collecting channels receiving hood with support from the four corner lifting cylinders for example in the case of a band part which is bent upwards at the top, can be raised immediately and repair and / or maintenance is simplified.
  • each device for hydromechanical descaling of continuously cast slabs and / or hot-rolled metal strip 20, in particular made of steel each comprises one Belt side 3, 4 assigned, one behind the other in the belt running direction and laterally to each other water spray nozzles 1, 1 'arranged in a row for spraying of high pressure water jets 10, 10 'at about 600 bar on both sides Belt surfaces.
  • the nozzle rows 1 assigned to the belt top 3 are together with gutters 2 each around a parallel to the belt surface and Belt longitudinal center plane vertical axis can be swiveled and are made to measure the signal of a measuring device (not shown) opposite the top 3 height adjustable.
  • the rows of nozzles 1 are together with the ones receiving them Spray bar 5 and thus interacting gutters 2 on the Band top 3 within a receiving these with their pivot axes Hood 6 arranged.
  • the hood 6 is of four corner the top driver roles 8 each associated lifting cylinders 7 worn.
  • the interior of the Hood 6 is in height, width and length to avoid interfering edges and turbulence zones comparatively generous for water and scale.
  • the hood 6 can be uncoupled from the driver rollers 8 by means of a detachable connection.
  • the hood 6 is shown in the raised position in FIG. 2, after decoupling the driver roller 8 from left-hand jack cylinders 7 the Driver roller 8 'shown in dashed lines continues with the counter roller below the Band 20 cooperates and the band can be pulled.
  • the construction of the scale washer is designed so that the upper part with hood 6, lifting cylinders 7, driver rollers 8 and pipe connections can preferably be lifted off by means of a crane for repair and / or maintenance.
  • Spray tubes 13 for low pressure water of 10 bar, for example Breaking up the scale arranged by spontaneous temperature quenching are. It can also be very helpful to provide that behind the scale washer at least one spray tube 13 'for the final cleaning of the strip 20 from dissolved scale is arranged.
  • the spray bars 5 'of the belt underside 4 are independent of the spray bars 5 the top of the belt 3 can be lowered.
  • the belt 20 runs, as is generally customary, on drivable transport rollers of the roller table 14.
  • the water gutters 2 are independent of the direction of belt travel the water spray nozzles 1 can be pivoted about a pivot point 9 and are opposite the band 20 with its mouth 12 automatically adjustable in height.
  • the mouth is in an undisturbed operating state 12 of the gutters 2 lying loosely on the belt surface 3 of the belt 20 slides along, but if, for example, an upturned ribbon head occurs (Fig. 1 left side) automatically by pivoting about the pivot point 9 from the Belt surface is lifted off.
  • an upturned ribbon head occurs (Fig. 1 left side) automatically by pivoting about the pivot point 9 from the Belt surface is lifted off.
  • An embodiment of the device provides, as shown in Figure 2, that the hood 6 together with the spray bar 5 and gutters 2 by means of Lift cylinder 7 comparatively high to release a free passage from Band 20 can be raised.
  • FIGS. 1 and 2 show, the design according to the invention realizes one 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 faults.
