Definitions

  • this cooling device is in the Middle region on the one hand and in the two outer regions on the other hand via its own, individually controllable valve means a liquid cooling medium fed.
  • the mean flow rate defines a symmetrical trapezoid whose parallel sides run transversely to the transport direction. The trapezoid and the two outer triangles complement each other to form a rectangle.
  • the control takes place in such a way that the quantity of coolant applied to the flat rolling stock via the two outer regions and the quantity of coolant applied to the flat rolling stock over the central region are coordinated with one another such that a temperature of edge regions of the flat rolled product is at a temperature of a central region of the flat Walzguts is adjusted.
  • the flat rolled stock may have a temperature wedge, as seen across the width of the flat stock, i. that the flat rolling stock is warmer on one side than on the other side. In such a case it would be advantageous to be able to cool one side of the flat rolling stock more than the other side. For this purpose, the procedure described above is unsuitable.
  • the US 2002/104597 A1 shows a casting rolling mill with a Steckel Mill, immediately after the roller table of the actual casting a quench cooling device is used, by means of a structural transformation of the metal strand produced preferably between the transformation temperatures Ar 3 and Ar 1 is performed.
  • this cooling device the continuous slab is applied at its top and bottom respectively with water or a water-air mixture of corresponding spray nozzles, the entirety of these nozzles is divided at the top and bottom in each case in several groups (137a - 137d corresponding FIG. 3 ) and these nozzle groups extend in the transport direction of the metal strand and can be acted upon independently of each other with water or a water-air mixture.
  • Each individual nozzle group consists of a plurality of symmetrical to the center line of the metal strand arranged rows 130 of individual nozzles, which are supplied via a common supply line with the cooling medium and wherein the coolant flow of each nozzle group is controlled in each case by a separate device 146 a - 146 d.
  • a separate device 146 a - 146 d At least the central nozzle group 137d, which has at least one third row of nozzles along the center line of the metal strand, forms a central region and the remaining nozzle groups form mutually symmetrical, outer regions of the cooling device.
  • any achievable cooling profile is also symmetrical due to the spatially-symmetrical arrangement of the nozzles, so that a temperature wedge in the metal strand transverse to the transport direction can not be compensated.
  • the preamble of claim 1 is based on US 2002/104597 A1 , Also the JP S51-147449 A shows chilled beams whose effect on the produced metal strand can be set individually or as a group ( Fig. 2 . Fig. 5 ), but this is only possible symmetrically in the width direction of the strand.
  • cooling bars are disclosed in which the outlet width of the coolant is adjustable by means of electromagnetic valves or mechanical slides ( Fig. 3, Fig. 4
  • these embodiments also do not allow availabilityabsch cooling effect to eliminate a temperature key of the rolling stock, since the corresponding spray nozzles can be opened or closed only in an adjustment only completely.
  • the object of the present invention is to provide opportunities to eliminate such a temperature wedge.
  • the valve devices are switched to binary, so are at a certain time either fully open or fully closed.
  • the amount of liquid cooling medium fed into the regions may be adjusted by adjusting a working pressure generated by a respective pump and / or by adjusting a delivery rate effected by the respective pump.
  • the valve devices can be designed as servo valves or as proportional valves.
  • the liquid coolant in front of the valve means may be at a constant pressure, for example because upstream pumps produce a constant pressure or because a supply is from a high tank.
  • the spray bar is usually above the Passline arranged.
  • the spray bar may alternatively be arranged below the passline. Often, however, there is more than just a spray bar.
  • the number of spray bars is therefore at least two. In this case, preferably at least one spray bar is arranged above and below the passline.
  • At least one of the spray bars may be arranged on a holding frame fixed relative to the pass line.
  • this spraying bar may be associated with an adjusting device by means of which a distance of this spray bar from the passline is adjustable.
  • This embodiment can be used in particular to maximize the distance from the passline when maintenance work on the spray bar and / or for example on a passport defining roller table should be made.
  • An adjustment range, by which the distance is variable, can be determined as needed. It is preferably at least 20 cm, for example at least 30 cm, in particular at least 50 cm. Even larger values are possible.
  • the two measures ie the adjustment of the distance and pivoting, can also be combined with one another in the same spray bar.
  • the corresponding spray bar is arranged on an intermediate frame, which in turn is arranged on a retaining frame fixed relative to the pass line.
  • the spraying bar and the intermediate frame are each assigned an adjusting device. It is possible that a distance of the spray bar from the intermediate frame is adjustable by means of the adjusting device associated with the spray bar.
  • the intermediate frame by means of the adjustment device associated with the intermediate frame can be pivoted about the pivoting angle about the pivot axis.
  • the reverse approach can be taken.
  • the spray bar can be pivoted about the pivoting angle about the pivoting axis.
  • the distance of the intermediate frame from the holding frame is adjustable in this case.
  • the pivot axis is generally arranged transversely to the transport direction at the edge of this spray bar and extends parallel to the transport direction.
  • the swivel angle can be determined as needed. Preferably, it is at least 20 °.
  • the pivoting angle can be at least 30 °, at least 45 ° or at least 60 °. Even larger tilt angles - even up to 90 ° and beyond - are possible.

  • the passline 3 can be defined for example by the arrangement of an upstream device and / or a downstream device.
  • the upstream device can be designed, for example, as a casting device, as an oven or as a rolling stand.

  • the cooling device 1 has a number of spray bars 5, 6. It is possible that only a single spray bar 5, 6 is present. In general, however, a plurality of spray bars 5, 6 are present, so at least two spray bars 5, 6. In this case, as shown in FIG FIG. 1 Preferably, at least one of the spray bars 5, 6 is arranged above and below the pass line 3.

  • a respective separate valve means 10, 11, 12, a liquid cooling medium 13 can be fed.
  • the valve devices 10, 11, 12 are individually controllable by a control device 14. The control of each of the valve devices 10, 11, 12 is thus independent of the control of the respective other two valve devices 11, 12 and 10, 12 and 10, 11th
  • the flat rolling stock 2 is acted upon by means of outlet openings 15, which are arranged in the central region 9, with a flow rate V1 of the liquid cooling medium 13.

  • the mean quantity profile V1 is according to FIG. 3 transverse to the transport direction x seen in the middle maximum. Towards the edge, the mean volume profile V1 decreases. The waste is linear at both edges.
  • the mean quantity curve V1 thus defines a middle triangle. One side of the middle triangle runs transversely to the transport direction x. The other two sides of the middle triangle are the same length. The middle triangle is thus an isosceles triangle.
  • the left outer quantity profile V2 is according to FIG. 3 transverse to the transport direction x seen at the left edge maximum. Towards the middle, the left outer flow V2 falls off. The waste is linear towards the middle.
  • the left outer quantity profile V2 thus defines a left outer triangle. One side of the left outer triangle runs parallel to the transport direction x. Another side of the left outer triangle runs transversely to the transport direction x. The left outer triangle is therefore a right-angled triangle.
  • the right outer flow rate V3 is according to FIG. 3 transverse to the transport direction x seen at the right edge maximum. Towards the middle, the right outer flow rate V3 drops off. The waste is linear towards the middle.
  • the right outer quantity curve V3 thus defines a right outer triangle. One side of the right outer triangle runs parallel to the transport direction x. Another side of the right outer triangle runs transversely to the transport direction x. The right outer triangle is also a right triangle.
  • the outlet openings 15, 16, 17, for example, as shown in FIG. 2 be arranged in several rows, which follow each other as seen in the transport direction x.
  • the outlet openings 15, 16, 17 may be designed accordingly, so that the amount of cooling medium 13 emerging from the respective outlet openings 15, 16, 17 varies.
  • volume curves V1, V2, V3 represent the maximum possible quantity curves.

  • the right outer region 8 is supplied via the associated valve device 12, a slightly lower flow rate M3.
  • the central region 9 associated with the valve device 10 is closed.

  • FIG. 7 are supplied to the right outer region 8 and the central region 9 delivery amounts M1, M3, which complement each other in the right part of the flat rolling stock 2 to a constant flow rate V.
  • the delivery amount M2 supplied to the left outer region 7 could be smaller than the delivery amount M3 supplied to the right outer region 8. In this case, the left edge of the flat rolling stock 2 from the middle of the flat rolled material 2 cooled weaker, so the resulting quantity course fall off.
