Definitions

  • the above items are well known. Purely by way of example, the DE 101 29 565 A1 and the corresponding one US 2004/0 006 998 A1 to get expelled.
  • the US 3,241,735 A shows a manufacturing method and a device for flat rolled metal, - the flat rolled is first hot-rolled in at least one roll stand, then in a horizontal transport direction (x) at a transport speed (v) is fed to a cooling section downstream of the roll stand and finally in the Cooling section is cooled, - the flat rolling stock being oriented horizontally during the rolling in the roll stand. During cooling, the belt is rotated from the horizontal position to a vertical position.
  • the flat rolling stock is cooled in the cooling section of a rolling mill after hot rolling.
  • Exact temperature control in the cooling section is particularly common in order to set the desired material properties of the flat rolled stock and to keep it constant with the lowest possible statistical spread.
  • Examples of such cooling sections are the cooling section of a hot strip mill with or without intensive cooling or the so-called Quette of a heavy plate mill.
  • liquid coolant usually water
  • the coolant applied to the underside can then fall down due to the force of gravity, so that the coolant which is applied to the flat rolling stock from below at a specific point on the cooling section does not interfere with the subsequent, further cooling of the underside of the flat rolling stock.
  • Coolant applied to the top can remain on the flat rolling stock. On the one hand, this causes undefined cooling.
  • the remaining coolant influences the cooling effect that subsequent, further cooling of the top of the flat rolling stock is to be brought about.
  • the flat rolling stock can bend upwards in the event of uneven cooling, so that the coolant collects in the middle. Other problems arise at higher transport speeds.
  • a system is also known in which the flat rolling stock is designed as a strip and is set up vertically in the cooling section during cooling. This system achieves uniform cooling on both sides. However, this method can only be used with relatively narrow and thin bands be applied. There is also the risk that the tapes on the side edge on which they are guided are damaged.
  • the object of the present invention is to create possibilities by means of which a defined cooling can be achieved on both sides of the flat rolling stock and nevertheless the risk of damage to the flat rolling stock, in particular on the side edge, can be reliably avoided.
  • the flat rolling stock is preferably rotated back about the axis at the first acute angle when it leaves the cooling section and / or after it leaves the cooling section, so that the flat rolling stock is oriented horizontally again after completion of the reverse rotation.
  • the further processing and processing of the flat rolling stock after cooling can take place in the usual way.
  • the first acute angle must be large enough that the coolant reliably flows off the top of the flat rolling stock.
  • the first acute angle is in the range between 5 ° and 30 °, in particular between 10 ° and 25 °, for example at approximately 15 ° to 20 °. In individual cases, however, larger angles - even beyond 45 ° - are possible. In very rare individual cases, a smaller angle may also be possible.
  • the flat rolling stock is guided and supported from the roll stand to the cooling section and in the cooling section by successive transport rollers in the transport direction, the transport rollers being rotatable about first axes of rotation are.
  • the raising and / or lowering of the flat rolling stock is preferably effected gradually by a corresponding orientation of the first axes of rotation of successive transport rollers.
  • the flat rolling stock is preferably fixed in the region in which it is oriented obliquely, as seen in the width direction of the flat rolling stock, by a guide device arranged on the side of the flat rolling stock. In this way, an exact lateral guidance of the flat rolling stock can be ensured in particular. This measure thus enables precise edge masking in particular.
  • the guide device can in particular have retaining rollers, which are arranged one behind the other as seen in the transport direction of the flat rolling stock and can be rotated about second axes of rotation.
  • the second axes of rotation preferably form a second acute angle with the width direction of the flat rolling stock, the legs of which both have an upward component.
  • the retention rollers are therefore inclined inwards in relation to the roller table defined by the transport rollers. This measure makes it difficult for the head of the flat rolling stock to fly up.
  • the sum of the first acute angle and the second acute angle is preferably less than 90 °, in particular less than 85 °. As a result, the head of the flat rolling stock can be prevented from flying up particularly reliably.
  • the sum of the first acute angle and the second acute angle should, however, be greater than 75 °, in particular greater than 80 °.
  • the transport speed is greater than 11.5 m / s, in particular greater than 15 m / s.
  • a device of the type mentioned at the outset is designed in such a way that, at least in a central region of the cooling section, the first axes of rotation form a first acute angle with the horizontal and the transport rollers are oriented in such a way before the inlet of the cooling section and / or in the inlet of the cooling section that the first axes of rotation of successive transport rollers gradually run more and more obliquely until the first acute angle is reached, or the associated transport rollers can be pivoted about an axis running in the transport direction.
  • the transport rollers behind the outlet of the cooling section and / or in the outlet of the cooling section are preferably oriented such that the first axes of rotation of successive transport rollers gradually run less and less until the horizontal is reached, or the associated transport rollers are about an axis running in the transport direction swiveling.
  • the device preferably has a guide device on the lower side, by means of which the flat rolling stock is fixed in the width direction of the flat rolling stock. In this way, an exact lateral guidance of the flat rolling stock can be ensured in particular. This measure thus enables precise edge masking in particular.
  • the guide device preferably has retention rollers which are arranged one behind the other in the transport direction of the flat rolling stock and can be rotated about second axes of rotation, the second rotating axes forming a second acute angle with the width direction of the flat rolling stock. whose legs both have an upward component. This measure makes it difficult for the head of the flat rolling stock to fly up.
  • the sum of the first acute angle and the second acute angle is preferably less than 90 °, in particular less than 85 °.
  • a device for producing a flat rolling stock 1 has a rolling stand 2.
  • the flat rolling stock 1 is made of metal.
  • the metal can in particular be steel. Alternatively, it can be another metal, for example aluminum, brass or copper.
  • the flat rolling stock 1 can be a strip or a heavy plate. In the case of a strip, the flat rolling stock 1 has a thickness d (see FIG 2 ) of less than 26 mm. The thickness d is often much smaller. For example, the thickness d of the flat rolling stock 1 can only be approximately 2 mm. The thickness d can also be smaller, for example only 0.8 mm, 1 mm or 1.5 mm. In the case of a heavy plate, the flat rolling stock 1 has a thickness d of at least 3 mm.
  • the flat rolling stock 1 extends in a transport direction x over a length l. If the flat rolling stock 1 is a strip, the length l can be several meters. In particular, the length l in this case is usually in the two-digit or three-digit meter range. In the case of very thin strips, the length l can even be over 1 km. In the case of a heavy plate, the length l is a few meters, usually a maximum of 100 m.
  • the flat rolling stock 1 extends in a width direction y over a width b. The width b can - but does not have to - be 1 m and larger.
  • the roll stand 2 can have further rolls, for example support rolls in the case of a four-high stand or back-up rolls and intermediate rolls in the case of a sex stand.
  • the flat rolling stock 1 is hot rolled in the roll stand 2.
  • the rollers 3 are rotatable about roller axes 4.
  • the roller axes 4 run horizontally and are arranged one above the other. Accordingly, the flat rolling stock 1 is oriented horizontally during rolling in the roll stand 2. After rolling in the roll stand 2, the flat rolling stock 1 runs in a horizontal transport direction x and at a transport speed v from the mill stand 2. Under certain circumstances, the transport speed v can be greater than 11.5 m / s, in particular greater than 15 m / s.
  • the device also has a cooling section 5.
  • the cooling section 5 is arranged downstream of the roll stand 2.
  • the flat rolling stock 1 is thus fed to the cooling section 5 after it leaves the rolling stand 2.
  • the flat rolling stock 1 is cooled in the cooling section 5.
  • the flat rolling stock 1 is cooled in the cooling section 5 while it is oriented obliquely.
  • "Obliquely oriented” here means that the flat rolling stock 1 corresponds to the representation in FIG FIG 3 is rotated about an axis extending in the transport direction x, so that one side edge 6 of the flat rolling stock 1 is oriented further up than the other side edge 7 of the flat rolling stock 1.
  • the device has transport rollers 8 for transporting the flat rolling stock 1 from the rolling stand to the cooling section 5 and for transporting the flat rolling stock 1 through the cooling section 5 (and generally also behind it).
  • the transport rollers 8 follow one another as seen in the transport direction x. They have first axes of rotation 9, around which the transport rollers 8 can be rotated.
  • the transport rollers 8 are thus arranged between the roll stand 2 and the cooling section 5, in the cooling section 5 and generally also behind the cooling section 5.
  • the flat rolling stock 1 is guided and supported by the rolling stand 2 to the cooling section 5 by means of the transport rollers 8, guided and supported by the cooling section 5 and - at least as a rule - also guided and supported behind the cooling section 5.
  • the flat rolling stock 1 is guided in the horizontal transport direction x.
  • the reference numerals for the transport rollers 8 and the first axes of rotation 9 are in some cases additionally supplemented with a small letter (a, b,%) In order to be able to distinguish them from one another if necessary. As far as generally below only from the transport rollers 8 and the first axes of rotation 9 The addition is omitted by the small letter.
  • the first axes of rotation 9 of the transport rollers 8 are as shown in FIG FIG 2 horizontally oriented.
  • the first axes of rotation 9 of the transport rollers 8 are as shown in FIG FIG 3 oriented at a first acute angle ⁇ .
  • the corresponding first axes of rotation 9 thus form the first acute angle a with the horizontal H.
  • the flat rolling stock 1 rests on the transport rollers 8, the flat rolling stock 1 is also oriented at the first acute angle ⁇ within the cooling section 5.
  • the first acute angle ⁇ is preferably in the range between 5 ° and 30 °, in particular between 10 ° and 25 °.
  • the first acute angle ⁇ can be approximately 15 ° to 20 °.
  • the flat rolling stock 1 is rotated about an axis extending in the transport direction x by the first acute angle ⁇ . After completion of the rotation about the axis, the flat rolling stock 1 is thus oriented obliquely, as in FIG FIG 1 and also in FIG 3 is shown.
  • the flat rolling stock 1 is rotated before the flat rolling stock 1 enters the cooling section 5, that is to say before cooling begins in the cooling section 5.
  • the flat rolling stock 1 can also be rotated when it runs in of the flat rolling stock 1 into the cooling section 5.
  • FIG 6 it is as shown in FIG 6 alternatively, it is possible that to rotate the flat rolling stock 1 by the first acute angle ⁇ , the horizontal positioning of the flat rolling stock 1 in the width direction y of the flat rolling stock 1 is raised on one side edge 6 and lowered on the other side edge 7.
  • the associated first axes of rotation 9a to 9e are shown in the 4 to 6 the associated first axes of rotation 9a to 9e.
  • the transport rollers 8 generally have uniform diameters, the representations in FIGS 4 to 6 also valid for the upper edges of the associated transport rollers 8a to 8e on which the flat rolling stock 1 rests.
  • the raising and / or lowering of the flat rolling stock 1 is thus gradually effected by a corresponding orientation of the first axes of rotation 9a to 9e of successive transport rollers 8a to 8e.
  • the representations of the 3 to 6 show the corresponding orientation of the transport rollers 8 or the first axes of rotation 9 in the operating state, while the flat rolling stock 1 is first rolled in the roll stand 2 and then cooled in the cooling section 5. It is possible that this orientation is static. Alternatively, it is possible for the transport rollers 8 to be pivotable individually or in groups about the axis running in the transport direction x. For example, according to the representation in FIG 3 there are hydraulic actuators 10, by means of which a corresponding adjustment of the orientation can be effected. It is even possible to pivot the transport rollers 8 out of the horizontal H only after the head of the flat rolling stock 1 has already passed the respective transport roller 8. It is also possible to provide a correspondingly staggered pivoting of the transport rollers 8. This is explained below using an example, the numerical values below being purely exemplary.
  • the flat rolling stock 1 After leaving the cooling section 5 - in individual cases already when leaving the cooling section 5 - the flat rolling stock 1 is rotated again. In individual cases, it may make sense to continue rotating the flat rolling stock 1 until the flat rolling stock 1 is completely vertically oriented. As a rule, however, the flat rolling stock 1 is rotated back by the first acute angle ⁇ about the axis extending in the transport direction x, so that the flat rolling stock 1 is oriented horizontally again after completion of the reverse rotation. This is from the representation in FIG 1 evident.
  • FIG 7 shows the to FIG 4 inverse case.
  • the corresponding transport rollers 8 and the associated first axes of rotation 9 can also be reversed FIG 5 or inverse to FIG 6 be oriented. Regardless of which configuration is implemented, however, the raising and / or lowering of the flat rolling stock 1 is gradually effected by a corresponding orientation of the first axes of rotation 9f to 9j of successive transport rollers 8f to 8j.
  • FIG 7 shows the corresponding orientation of the transport rollers 8 or the first axes of rotation 9 in the operating state, so that the flat rolling stock 1 is first rolled in the roll stand 2 and then cooled in the cooling section 5. It’s like before 3 to 6 possible that this orientation is static. Alternatively, it is also possible here that the transport rollers 8 can be pivoted individually or in groups about the axis running in the transport direction x. The comments on the 4 to 6 are applicable in an analogous manner.
  • the device preferably has a guide device on the lower side, at least in the area in which the first axes of rotation 9 of the transport rollers 8 form the first acute angle ⁇ 11 on.
  • the flat rolling stock 1 is fixed in the width direction y of the flat rolling stock 1 by means of the guide device 11.
  • the guide device 11 can be designed, for example, as a rail running in the transport direction x of the flat rolling stock 1.
  • the guide device 11 can be shown in FIG FIG 3 Have retaining rollers, which are arranged one behind the other as seen in the transport direction x of the flat rolling stock 1 and in turn are rotatable about second axes of rotation 12.
  • the second axes of rotation 12 form a second angle ⁇ with the width direction y of the flat rolling stock 1.
  • Both the respective second axis of rotation 12 and the width direction y of the flat rolling stock 1 each form a leg 13, 14 of the second angle ⁇ .
  • Both legs 13, 14 have an upward component. It is possible that the horizontal components of the two legs 13, 14 point in opposite directions.
  • the second angle ⁇ can be as shown in FIG 3 be a right angle.
  • the second angle ⁇ is preferably an acute angle.

  • the leg 13 formed by the second axis of rotation 12 has no horizontal component, ie it points vertically upward.
  • the sum is preferably as shown in FIG 9 less than 90 °, in particular less than 85 °.
  • the horizontal components of the two legs 13, 14 point in the same direction.
  • the sum of the two acute angles ⁇ , ⁇ is preferably greater than 75 °, in particular greater than 80 °.
  • the present invention has many advantages.
  • the coolant flows even at a relatively small value of the first acute angle ⁇ of, for example, only 20 ° quickly and reliably by itself from the top of the flat rolling stock 1 from the side.
  • the lateral drainage is facilitated in particular by the steam film, which forms very quickly on the top of the flat rolling stock 1 between the flat rolling stock 1 and the coolant.
