Definitions
- the object of the present invention is to develop a cooling section of the type mentioned in such a way that the problems of the prior art no longer occur.
- This configuration ensures that in the event of damage or clogging of the spray nozzles only the plate-shaped closing element must be removed, which is usually relatively easy and fast to accomplish. Then, a new (properly functioning) plate-shaped closure element is installed. Thereafter, the cooling section can be operated again. A repair or general repair of the dismantled end element can be done outside the cooling section.
- the spray bar is arranged above the passline, that is designed as an upper spray bar.
- the advantages of the present invention are particularly important in a cooling section to bear, in which the spray bar is arranged below the passline, that is designed as a lower spray bar.
- the non-destructive detachable connection can be formed as needed.
- the non-destructive releasable connections may be formed as a clamping connection, for example as a screw connection.
- the spray nozzles are formed as incorporated into the plate-shaped end element recesses. This ensures that the spray nozzles - in contrast to the prior art - no longer protrude beyond the closing element. A risk of damage is thus reduced to almost zero.
- the recesses have a respective longitudinal axis and, seen transversely to the longitudinal axis, a cross section. Preferably is seen in the direction of the flat rolling stock to the cross section constant or at least partially tapers.
- the spray bar is preferably operated at a working pressure of at least 0.5 bar.
- FIG. 1 is passing through a cooling section of a flat rolling stock 1 in a transport direction x at the level of a passline 2.
- the flat rolling stock 1 may be, for example, a heavy plate or a hot strip. It can in particular consist of steel.
- the cooling section has for cooling the flat rolling stock 1, usually at least above the passline 2 at least one spray bar 3, hereinafter referred to as the upper spray bar 3. In most cases, the cooling section also has below the passline 2 at least one spray bar 4, hereinafter referred to as the lower spray bar 4.
- the upper spray bar 3 and the lower spray bar 4 are seen arranged in the transport direction x usually at the same position.
- the spray bars 3, 4 extend according to FIG. 2 transverse to the transport direction x. Often even several upper and lower spray bars 3, 4 are present. In 1 and FIG. 2 However, only one such spray bar 3, 4 is shown in order not to overload this FIG.
- the lower spray bar 4 has according to FIG. 3 a base part 5 on.
- the lower part 6 and the upper part 7 are detachably connected in this case via screw 8.
- the base part 5 may consist of a single part.
- the base part 5 is closed at this side by means of a plate-shaped end element 9.
- the closing element 9 is connected to side walls 10 of the base part 5 by means of a non-destructive detachable connection 11.
- the non-destructive detachable connection 11 may be formed, for example, as a clamping connection 11, that is, the final element 9 is pressed against abutting surfaces 12 of the side walls 10 due to the clamping connection 11.
- the clamping connection 11 may be formed, for example, as a screw 11.
- the plate-shaped end element 9 is - as the base part 5 also - usually made of steel. It runs horizontally.
- the side walls 10 of the base part 5, however, are vertical or at least steep.
- the term "steep" is intended to mean that the side walls 10 form an angle of maximum 20 ° with the vertical, more preferably 10 ° or less. In general, the angle is, if it is different from 0 °, between 2 ° and 6 °.
- Spray nozzles 13 introduced.
- a liquid coolant 14 which is fed into the lower spray bar 4 is sprayed onto the flat rolling stock 1.
- the spray nozzles 13 may be formed as separate, releasably connected to the plate-shaped end element 9 elements.
- the spray nozzles 13 are integral components of the plate-shaped end element 9.
- the spray nozzles 13 do not protrude beyond the plate-shaped closing element 9.
- the recesses 13 each form at least two outer rows 15, 16 of recesses 13.
- the outer rows 15, 16 extend transversely to the transport direction x and are arranged one behind the other in the transport direction x.
- at least one middle row 17 of recesses 13 may be present. If the middle row 17 of recesses 13 is present, it is arranged in the transport direction x between the outer rows 15, 16.
- the recesses 13 of the outer rows 15, 16 have according to FIG. 4 a respective main spray direction 18, 19, hereinafter referred to as outer main spray directions 18, 19.
- the outer main spray directions 18, 19 have a (common) vertical component.
- the outer main spray directions 18, 19 are shown in FIG FIG. 4 Furthermore, a respective horizontal component.
- the horizontal components of the outer main spray directions 18, 19 run parallel to the transport direction x. As a rule, the horizontal components of the outer main spray directions 18, 19 are directed away from one another.
- the recesses 13 of the middle row 17 also have a respective main spray direction 20, hereinafter referred to as the mean main spray direction 20.
- the central main spray direction 20 is, if the middle row is present, directed purely vertically. So it has only the vertical component, but no horizontal component.
- the recesses 13 have according to FIG. 4 a respective longitudinal axis 21. Seen transversely to the respective longitudinal axis 21, the recesses 13 have a-generally circular-cross-section. Vorugtician, the cross-section tapers in the direction of the flat rolling stock 1 at least in sections.
- the recesses 13 may have, for example, a starting section 22, a middle section 23 and an end section 24.
- the respective starting section 22 and the respective central section 23 can conically taper, for example, while the respective end section 24 extends cylindrically.
- the respective starting section 22 has a more conical course than the respective central section 23.
- the cross section may be constant in the direction of the flat rolling stock 1.
- the basis of the FIG. 3 and 4 explained lower spray bar 4 is preferably used in a so-called intensive cooling.
- the lower spray bar 4 is operated at a working pressure p which is at least 0.5 bar. Most of the working pressure p is even above 1.0 bar, for example at 2.0 bar to 3.5 bar.
- the present invention has many advantages.
- a complete replacement of the plate-shaped closure element 9 is possible in a simple and fast way.
- the spray nozzles 13 are integral parts of the plate-shaped closing element 9, is still a Risk of damage to the spray nozzles 13 almost impossible.
