Description

technical area

The present invention relates to a rolling line for producing a metal strip, in particular a hot rolling line for producing steel strips, and a method for producing a rolling train.

was standing of the technology

For the production of metal strips, in particular in the production of sheets, rolling mills are used. In a rolling mill, a plurality of rolling stands are usually connected in series, which perform the actual rolling process. For this purpose, for example, a slab, which originates from a continuous casting plant, or a preliminary sliver is passed through the successive rolling stands in a continuous process. The rolling stands in this case have work rolls, between which the metal to be rolled passes, wherein the work rolls are pressed with a rolling pressure against the metal to be rolled. Lie in the individual rolling stands progressively thinner rolling gaps, so that after the last rolling stand, the desired thickness of the rolled metal strip is reached.

Between the rolling stands loops are conventionally provided, which serve on the one hand to control the strip tension between two successive rolling stands, and on the other hand are used to compensate for mass flow disturbances. Accordingly, the tape is deflected out of its flat position, in order to provide a tape store by means of which the corresponding control can be carried out.

From the DE 40 28 542 A1 a device for intermediate heating of hot rolled strip between two adjacent rolling stands of a hot strip mill is known, wherein the belt is guided under deflection from the belt level via pulleys in a variable length sling.

From the EP 0 415 987 B2 For example, there is known a method for the continuous production of strip steel or sheet steel from sheet products produced by the sheet continuous casting method. Inductive heating is provided between the stands.

From the EP 369 555 A2 For example, there is known a method for producing hot rolled steel strip from a strip-shaped continuously cast molding material, in which the stand roller sets are arranged at a reduced distance from one another, wherein loop rolls are not provided.

description

The object of the present invention is to develop the conventional rolling mills in such a way that the rolling efficiency can be further improved.

This object is achieved by a rolling train for producing a metal strip, in particular a hot rolling mill for the production of Stahlbändem according to claim 1. Advantageous embodiments are specified in the subclaims.

Accordingly, the rolling train comprises at least one roll stand for rolling the metal strip, at least one aggregate adjacent to the roll stand, and at least one loop lifter disposed between the rolling stand and the adjacent aggregate with a loop lifter roll for regulating the strip tension and / or for compensating mass flow disturbances. According to the invention, the looper roll is arranged within the volume enclosed by one of the roll stands.

The volume of the roll stand is defined by the respective outer edges of the roll stand, that is, for example, the outer edges of the frame of the roll stand. Accordingly, at least the looper roller within the "shadow" of the rolling stand, so it is covered by the frame of the roll stand parallel to the recorded in the roll stand work rolls when looking sideways of the rolling mill, so that it is not visible. The looper roll is arranged parallel to the orientation of the work rolls of the rolling stand.

The aggregate arranged adjacent to the roll stand can be a further roll stand, a reel, a straightening machine, a winding furnace, etc.

By arranging the looper roll within the volume defined by one of the rolling stands, a very compact construction of the roll stand with the downstream looper can be achieved. In this way it can be achieved, for example, that the individual rolling stands can be arranged closer to one another, so that the distance between the individual rolling stands becomes smaller. This has both in terms of the resulting shorter length of the rolling mill advantages, as well as with respect to the quality of the rolling stock during hot rolling. When hot rolling namely the temperature loss is reduced due to the transport distances between the individual rolling stands here.

The compact arrangement can also be achieved that between the individual rolling stands at conventional distance (or at almost conventional distance) more space for other components such as induction heating, hold-down rollers, a belt cooling, a descaling, a leveler, a separator or a Scissors can be accommodated.

Preferably, the looper roller is arranged in a region between the rolling mill center and the rolling mill edge. In this way, a correspondingly compact design can be achieved.

The looper roller is preferably attached to a lever which is adjustable by means of an actuator, in particular by means of a hydraulic cylinder, hinged to the rolling stand.

Preferably, the lever is mounted within the volume defined by the rolling stand.

In a further preferred embodiment, the bearing of the lever, which carries the looper roller, outside the volume defined by the rolling mill.

Preferably, the looper roller can be arranged in the direction of tape travel in front of the bearing of the loop lifter.

Due to the flexible arrangement of the bearing of the looper roller carrying lever, a flexible use of the looper roll can be ensured. For example, for the operation of the roll stand in hot rolling operation, an arrangement of the loop lifter roll can be made within the volume defined by the rolling stand, such that an induction heater can additionally be driven onto the strip between two successive rolling stands.

In another variant or another mode of operation, the looper roller can be folded out, as it were, outside the volume defined by the rolling stand in accordance with the arrangement of the bearing, so that the looper roller is located outside the rolling stands between two successive rolling stands. In other words, a variable positioning of the looper roller is possible depending on the respective boundary conditions.

It may be provided to arrange a second loop lifter in addition to the (first) looper roll located in the shadow of the framework, in which frame the loop lifter roll is located outside the shade of the framework. Preferably, either one or the other looper roll can be used.

In a further preferred variant, the looper pulley is guided in a linear guide within the volume defined by the roll stand, preferably via an actuator, for example in the form of a hydraulic cylinder.

In a further preferred variant, behind the roll stand, within the volume of which the loop lifter roll is arranged, a hold-down roll for holding down the strip is arranged. The hold-down roller can also be arranged in the strip running direction behind the volume defined by the roll stand. By means of the hold-down roller, the belt can be returned to the roller level.

Preferably, in another variant, an adjusting device of an inlet side guide for guiding the strip as it enters a rolling stand is arranged within the volume defined by the rolling stand. Also in this way, a compact design of the rolling stand with the associated components can be achieved such that the inlet side guides continue to press into the roll stand. This, in turn, space can be saved between the rolling stands, in order to get closer in this way, either the rolling stands closer to each other, or to attach induction heaters or other components between the rolling stands can.

Between the stands, further components, such as an induction heater (eg transverse field inductors, a sliding inductor), hold-down rollers, a belt cooling, a descaling, a straightening machine, a separating device, a pair of scissors etc. are preferably arranged between the stands.

Particularly preferably, an induction heater for heating the strip is arranged between two adjacent roll stands, wherein the induction heating itself has a compact design and a high power density.

A compact design of the induction heating is understood to mean an induction heating which has a relatively small extent in the direction of strip travel. In particular, the expansion of the induction heating in the strip running direction is lower than previously known. The extension or length of the induction heating in the strip running direction is preferably less than 1500 mm and is preferably between 600 mm and 1100 mm. In this way, it is achieved that the distances between the roll stand and the adjacent aggregate, in particular a further roll stand, can be reduced, which results in a shortening of the entire rolling train and in an improved temperature control of the strip.

In this way it is further achieved that not only a Induktorpärchen the induction heating can be arranged between the rolling stands with a small footprint, but it is also the space required for the Induktorspeisung next to the rolling gears or the rolling motors reduced. For this purpose, the inductor feeds are preferably arranged on one side of the rolling train, particularly preferably on the drive side of the rolling train.

A flexible adjustment and adaptation of the induction heating to the bandwidth can be achieved by the provision of at least two adjacent mutually arranged inductors, which can be moved perpendicular to the band direction in each case. To save space in the direction of tape travel, the two Induktorspeisungen not only compact side by side, but particularly preferably arranged one above the other.

The inductor and the associated Induktorspeisung can be offset in the strip running direction against each other so that the inductor is not centrally located on the Induktorspeisung, but just offset. In this way, further space can be saved here and the simultaneous operation of two induction heaters one above the other can be achieved so that the Induktorspeisungen quasi have the same "footprint", but the inductors are shifted in the strip running direction from the middle of Induktorspeisungen out.

Furthermore, via busbars, for example, a rear inductor with an inductor arranged on top, and a front inductor with a bottom arranged Induktorspeisung be connected. Inductor and Induktorspeisung can be moved together with each other perpendicular to the direction of tape travel and be adjusted accordingly in their common position of the respective width of the belt without the induction heater would consume a lot of space in the direction of tape travel.

In order not to accidentally heat up the respective units adjacent to the induction heater, the induction heater must maintain a certain minimum distance from the respective units. Preferably, a minimum distance of 150 mm is maintained here. Preferably, this distance is also in Belt direction between the induction heating and the adjacent rolling stands, between which the induction heating is arranged, complied with. This results in a particularly compact arrangement of the looper roll and / or the side guide in the shadow of the respective adjacent rolling stands in combination with the arranged between these rolling stands compact induction heater.

Preferably, inductor and inductor are connected together so that they can be easily solved for maintenance purposes or in set-up operation of each other.

Instead of a Induktorpärchen also a single inductor (sliding inductor) can be used. In a structural unit, the width-adjustable inductor loops are arranged in such a way that symmetrical heating takes place over the bandwidth. This design is particularly compact.

The power density is preferably in a range of more than 1200 MW / m ² , preferably 3000 MW / m ² , this power density being determined by the power actually introduced into the metal strip.

By the above-mentioned characteristics, which can be combined with each other, a compact rolling mill can be achieved with a compact frame arrangement. By inductive heating of the metal strip and by a reduced framework distance can increase the temperature or at least lower temperature losses between the individual scaffolds can be achieved.

The compact arrangement of the loop lifter in the shadow of the mill stand is not limited to an application between two scaffolds, but may be in lack of space in the scaffold inlet or scaffolding outlet area of a rolling mill to neighboring aggregates out, for example, a reel, a winding furnace, etc., arranged.

The above-described object of the invention is further achieved by a method for forming a rolling train for producing a metal strip, in particular a hot rolling mill with the features of claims 28 to 31.

In particular, the rolling train comprises at least one rolling stand for rolling the metal strip, at least one aggregate adjacent to the rolling stand and at least one loop lifter disposed between the rolling stand and the adjacent aggregate with a loop-lifting roller for regulating the strip tension and / or for compensating mass flow disturbances, wherein according to the invention the loop lifter roll is inside of the volume defined by one of the rolling mills.

In a further embodiment of the method, the rolling train comprises at least one rolling stand for rolling the metal strip, at least one aggregate adjacent to the rolling stand and at least one between the rolling stand and the at least one unit arranged inlet side guide for inserting the metal strip in the subsequent roll stand, wherein according to the invention, the adjustment of the inlet side guide is disposed within the volume defined by the rolling mill.

Preferably, at least one arranged between the rolling mill and the at least one unit compact induction heating is provided for heating the metal strip.

In a further embodiment of the method, the rolling train comprises at least one roll stand for rolling the metal strip, at least one aggregate adjacent to the roll stand, and at least one induction heating arranged between the rolling stand and the at least one aggregate for heating the metal strip, wherein according to the invention the induction heating is compact with respect to its expansion in FIG Tape running direction is formed.

Detailed description the figures

Hereinafter, the present disclosure will be described in more detail based on the drawings of the figures. In this case, the same elements in the figures are provided with the same reference numerals and partially omitted repeated description of the respective elements.

FIG. 1 is an illustration of a rolling mill in the conventional manner.

Correspondingly, two rolling stands 10 are shown, which comprise a frame 12, in each of which two work rolls 14 and two support rolls 16 are provided. The frame 12 comprises a rolling stand center 100, a rolling stand leading edge 102 and a rolling stand trailing edge 104. The volume of the rolling stand 10 is defined by the edges of the rolling stand 10, in particular the rolling stand leading edge 102 and the rolling stand trailing edge 104, as well as the transverse extent of the rolling mill stand. In other words, the total enclosed space bounded outwardly by the frame 12 is the volume defined by the mill stand 10.

Between the two in FIG. 1 a roll lifter 20 is provided which comprises a loop lifter roller 22, a lever 24 which is articulated to a bearing 26, and an adjusting cylinder 28. The looper roller 22 is in contact with the metal strip 40 to be processed, which is in FIG. 1 from the left side through the two work rolls 14 of the first stand, is introduced via the loop lifter 20, in particular via the looper roll 22, in the second rolling stand 10.

In order to facilitate the insertion of the belt 40 into the respective downstream rolling stand 10, an inlet side guide 30 is provided. The inlet side guide 30 is used for clean introduction of the belt 40 in the subsequent roll stand. The inlet side guide can be adjusted via an adjusting device 32, such that it is adapted both to the bandwidth, as allows a more accurate insertion of the belt 40 in the subsequent rolling mill in a dynamic process.

In the in FIG. 1 As shown in the conventional example, both the loop lifter 20 and the inlet side guide 30 and the adjusting device 32 of the inlet side guide 30 are arranged outside the volume defined by the respective rolling stand 10. In particular, both the loop lifter roller 22 and the bearing 26 as well as the lever 24 and the adjusting cylinder 28 of the loop lifter 20 are arranged behind the frame trailing edge 104 of the first rolling stand 10. The adjusting device 32 of the inlet side guide 30 is arranged in front of the leading edge 102 of the following rolling stand. Accordingly, both the loop lifter 20 and the adjusting device 32 are arranged between the respective rolling stands.

In FIG. 2 Now, an apparatus according to the present disclosure is shown.

The looper roller 22 is correspondingly arranged within the volume defined by the rolling stand 10, and in particular within the volume defined by the frame 12 of the rolling stand 10. In particular, the looper roller 22 is disposed in a region between the rolling stand trailing edge 104 of the frame 12 and the rolling stand 10 and the rolling mill center 100. A large part of the lever 24 is also within the volume defined by the rolling stand 10. However, in this exemplary embodiment, the bearing 26 lies outside the volume defined by the roll stand 10. The same is the bearing of the adjusting cylinder 28. The looper is here compared to the conventional arrangement arranged vice versa, so the looper roller 22 is positioned in the strip running direction in front of the bearing 26.

With respect to the inlet side guide 30, the adjusting devices 32 of the inlet side guide are also accommodated within the volume defined by the rolling stand 10. In particular, the adjusting devices 32 of the inlet side guide 30 are arranged between the rolling stand leading edge 102 of the rolling stand 10 and the rolling mill center 100.

The corresponding arrangement of the looper roll 22 within the volume of the roll stand 10 can be achieved that more space is available between the two successive rolling stands to arrange there other components. For example, in FIG. 2 an induction heater 50 having two inductors 54 disposed adjacent to each other to form a pair. The induction heater 50 provides between the two rolling stands 10 for an additional heating of the belt 40, so that actively influenced in a hot rolling process, the temperature profile or the belt temperature can be increased and thus an improved rolling result can be achieved.

Also by the arrangement of the adjusting devices 32 of the inlet side guide 30 also additional space between the two rolling stands can be created.

The induction heaters 50 have a compact design with a high power density. The power density is preferably in a range of more than 1200 MW / m ² , preferably 3000 MW / m ² , this power density being determined by the power actually introduced into the metal strip. The extent of the induction heater 50, in particular the extent of the inductors 54 of the induction heater 50 in the tape running direction of the belt 40 is advantageously less than 1500 mm and is preferably between 600 mm and 1100 mm.

In order to keep the use of the induction heater 50 with respect to the tape guide simple, is in FIG. 2 In addition, a hold-down 60 is provided, which comprises a hold-down roller 62, which is in direct contact with the belt 40. The hold-down roller 62 is controlled so that the belt 40 is substantially in its original belt plane or at least in a belt plane in which the induction heaters 50 can be operated.

In order to keep the induction heater 50 away from water, for example, air blowers 52 are arranged in the region of the induction heater 50 in order to be able to blow the water off the metal strip. The metal strip can also be guided with a slight incline, for example between the hold-down roller 62 to the respective follower unit 10, so that the water flows off.

The tapping on the tape head can be done as usual, so that only one alternatively arranged between the stands 10 looper is engaged. The inductors 54 are adjacent to the tape at the time. The gap in the region of the inductors 54 is made by folding or transversely movable Überleittisehe filled (not shown), so that a secure transport of the tape head between the stands is guaranteed. Only after or already shortly before the puncture of the adjacent unit, for example, the neighboring rolling stand 10, the hold-down roller 62 is pivoted down (or linearly shifted), so that is provided for a defined band position and then one or more induction heaters laterally, preferably from the drive side to be driven between the scaffolding. The transfer tables are moved away after construction of the strip tension, so as to make room for the induction heaters. The hold-down roller 62 may additionally support the work of the loop lifter within predetermined limits.

The hold-down 60 comprises in addition to the hold-down roller 62 a lever 64, on which the hold-down roller 62 is articulated, and the lever 64 is fixed to a bearing 66. By means of an actuator 68, the hold-60 and in particular the hold-down roller 62 can be brought into the desired position.

How out FIG. 2 can be seen, can be achieved by means of the proposed structure on the one hand, that more space between the individual rolling stands remains at leisure, such that different components can be introduced, such as those in FIG. 2 shown induction heater 50, hold-down rollers 62 or, in another embodiment, a belt cooling, a descaling, a straightening machine or for example a separator.

FIG. 3 shows a variant of the in FIG. 2 shown embodiment of the present disclosure.

The variant refers to the looper 20, not here, as in FIG. 2 shown as designed via a lever hinged execution, but in FIG. 3 is guided in a linear guide. The linear guided looper 20 of the FIG. 3 Also includes a looper roll 22, which is received within the volume defined by the rolling stand 10 and is provided in particular between the trailing edge 104 and the frame center 100 of the roll stand 10. The linear guide is formed by a linear cylinder 29 acting directly on the looper roller 22.

FIG. 4 shows in a side view (top) and in a plan view (bottom) details of an induction heater 50 with inductors 54, which may be provided between two juxtaposed roll stands. In plan view, the two juxtaposed roller stands are indicated by the roller stand center lines 100. The belt 40 moves in plan view from bottom to top and in side view into the plane of the paper.

The inductors 54 in this illustration each comprise a conductor loop above and below the band 40, so that two inductors 54 form an inductor pair. The inductors 54 each consist of a C-shaped induction bow, which is open on the operating side BS of the rolling train and on the drive side AS at least by means of Induktorspeisungen 45, 46 is closed.

In the exemplary embodiment shown, an inductor pair with a total of two inductors 54 is arranged next to one another in the strip running direction of the strip. These are transverse field inductors. If required, a plurality of inductor pairs can also be arranged next to each other (not shown).

Depending on the width of the band 40, the two pairs of inductors can each be moved relative to one another perpendicular to the direction of strip travel, so that in total a symmetrical heating effect on the band 40 is achieved. The Induktorspeisungen 45, 46 are moved together with the respectively connected inductors 54 perpendicular to the tape running direction, as shown by the indicated in the Induktorspeisungen 45, 46 and inductors 54 arrows.

The inductors 54 with the respective Induktorspeisungen 45, 46 can be moved on the drive side AS in a waiting position so that they are completely removed from the transport area of the tape. From this waiting position, they can then be moved over the belt 40 into the operating position shown in the figure.

Not only the inductors 54 are formed compact in the tape running direction. It also reduces the space requirement of the Induktorspeisungen 45, 46 in the strip running direction of the belt 40, since the two Induktorspeisungen 45, 46 are arranged one above the other in the embodiment shown. In this case, the rear inductor 54 is connected to the upper inductor feed 45, and the front inductor 54 is connected to the lower inductor feed 46. The inductors 54 are included relative to the respective center of the Induktorspeisungen 45, 46 shifted by a distance a, to achieve an adjacent arrangement of the inductors 54 at approximately the same "footprint" of the device.

In this way, the space required in addition to the belt 40 in the region of the rolling gear and / or rolling motors, not shown in the figure, is reduced. The support elements or connecting elements of the individual inductor pairs 50 to the Induktorspeisungen 45, 46 are not shown in the figure.
