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.

State of the art

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. In the individual rolling stands are gradually thinner roll gaps, so that after the last roll 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 producing steel strips 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 for 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.

Due to the compact arrangement can be further achieved that between the individual Rolling stands at conventional distance (or at almost conventional distance) more space for other components, such as an induction heater, hold-down rollers, a belt cooling, a descaling, a leveler, a separator or 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.

Preferably, further components, such as induction heating (eg transverse field inductors, a sliding inductor), hold-down rollers, strip cooling, descaling, straightening machine, separating device, scissors etc., are 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, resulting in a shortening of the entire rolling train as well as resulting in an improved temperature control of the belt.

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 in each case perpendicular to the tape direction. 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 maintained in the strip direction between the induction heating and the adjacent rolling stands, between which the induction heating is arranged. 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 an inductive heating of the metal strip as well as by a reduced stand spacing temperature increases or at least lower temperature losses between the individual stands 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 roll stand for rolling the metal strip, at least an aggregate adjacent to the rolling stand and at least one loop lifter located between the rolling stand and the adjacent aggregate with a loop lifter roller for regulating the strip tension and / or for compensating mass flow disturbances, wherein according to the invention the loop lifter roll is arranged within the volume defined by one of the rolling stands.

In a further embodiment of the method, the rolling train comprises at least one rolling stand for rolling the metal strip, at least one unit adjacent to the rolling stand and at least one inlet side guide arranged between the rolling stand and the at least one unit for introducing the metal strip into the following rolling stand, wherein according to the invention the adjusting device of Inlet side guide is disposed within the volume defined by the rolling stand.

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 rolling stand for rolling the metal strip, at least one aggregate adjacent to the rolling 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 of 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.

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

Correspondingly, there are two rolling stands 10 shown which a frame 12 in which in each case two work rolls 14 and two back-up rolls 16 are provided. The frame 12 includes a rolling mill center 100 , a rolling mill front edge 102 and a rolling stand trailing edge 104 , Through the edges of the rolling stand 10 , in particular the rolling mill front edge 102 and the rolling stand trailing edge 104 , as well as the transverse extent of the roll stand, the volume of the roll stand 10 Are defined. In other words, the entire enclosed space is outside the frame 12 limited, that of the rolling mill 10 defined volumes.

Between the two in 1 shown rolling stands is a looper 20 provided that a looper roll 22 , a lever 24 , which is at a warehouse 26 is articulated, and an adjusting cylinder 28 includes. The looper roll 22 is in contact with the metal strip to be processed 40 which is in 1 from the left side through the two work rolls 14 of the first rolling mill, over the looper 20 , in particular via the looper roll 22 , into the second rolling stand 10 is introduced.

To insert the tape 40 in the respective downstream rolling stand 10 To facilitate, is an inlet side guide 30 intended. The inlet side guide 30 used for clean initiation of the tape 40 in the following rolling stand. The inlet side guide can via an adjustment 32 be adjusted so that it is both adapted to the bandwidth, as well as in a dynamic process, a more accurate insertion of the tape 40 in the following rolling mill allows.

In the in 1 The conventional example shown is both the loop lifter 20 as well as the inlet side guide 30 or the adjusting device 32 the inlet side guide 30 outside of the respective rolling stand 10 arranged volume. In particular, both the looper roll 22 as well as the camp 26 as well as the lever 24 and the actuator cylinder 28 the looper 20 behind the scaffold trailing edge 104 of the first rolling stand 10 arranged. The adjusting device 32 the inlet side guide 30 is in front of the front edge 102 of the following roll stand arranged. Accordingly, both the looper 20 as well as the adjusting device 32 arranged between the respective rolling stands.

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

The looper roll 22 is accordingly within that of the mill stand 10 , and especially within the frame 12 of the rolling stand 10 arranged volume. In particular, the looper roller is 22 in an area between the rolling stand trailing edge 104 of the frame 12 or of the roll stand 10 and the rolling mill center 100 arranged. Much of the lever 24 is also inside of the mill stand 10 defined volume. The warehouse 26 However, in this embodiment, outside of the rolling stand 10 defined volume. Just as the bearing of the adjusting cylinder 28 , The looper is here reversed relative to the conventional arrangement, so the looper pulley is 22 in strip running direction in front of the bearing 26 positioned.

Regarding the inlet side guide 30 are the adjustment devices 32 the inlet side guide also within the through the rolling stand 10 recorded volume. In particular, the adjusting devices 32 the inlet side guide 30 between the rolling mill front edge 102 of the rolling stand 10 and the rolling mill center 100 arranged.

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

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

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 induction heating 50 , in particular the extent of the inductors 54 the induction heating 50 in the tape running direction of the tape 40 is advantageously less than 1500 mm and is preferably between 600 mm and 1100 mm.

To the use of induction heating 50 to keep track of the tape guide is in 2 additionally a hold-down 60 provided, which a hold-down roller 62 which is in direct contact with the tape 40 stands. The hold-down roller 62 is regulated so that the tape 40 is substantially in its original belt plane or at least in a belt plane in which the induction heaters 50 can be operated.

To the induction heating 50 To be able to keep away from water, for example, air blows 52 in the field of induction heating 50 arranged to blow the water from the metal band can. The metal band can also be performed with a slight slope, for example between the hold-down roller 62 to the respective follower unit 10 so that the water drains off.

The tap on the tape head can be done as usual, leaving only an alternative between the scaffolding 10 arranged looper is engaged. The inductors 54 stand next to the band at the time. The gap in the field of inductors 54 is filled by fold-up or transversely movable transfer tables (not shown), so that a safe transport of the tape head between the stands is guaranteed. Only after or already shortly before the puncture of the neighboring aggregate, for example the neighboring rolling stand 10 , becomes the hold-down roller 62 swung down (or linearly shifted), so that is provided for a defined band position and then one or more induction heaters laterally, preferably driven from the drive side, 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 In addition, the work of the looper can also be supported within specified limits.

The hold down 60 includes next to the hold-down roller 62 a lever 64 at which the hold-down roller 62 hinged, and the lever 64 is at a warehouse 66 attached. By means of an actuator 68 can the hold down 60 and in particular the hold-down roller 62 be brought into the desired position.

How out 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 2 Induction heating shown 50 , Hold-down rollers 62 or, in another embodiment, a belt cooling, a descaling, a leveler or, for example, a separator.

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

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

4 shows in a side view (top) and in a plan view (bottom) details of an induction heater 50 with inductors 54 , which can be provided between two juxtaposed roll stands. In the plan view, the two juxtaposed roll stands by the roll stand center lines 100 indicated. The ribbon 40 moves in the plan view from bottom to top and in the 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 couple. 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 closed is.

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

The two Induktorpärchen can each depend on the width of the band 40 perpendicular to the strip running direction so are moved against each other, so that in total a symmetrical heating effect on the tape 40 is reached. The inductor feeds 45 . 46 be together with the respective connected inductors 54 shifted perpendicular to the tape running direction, as by the in the Induktorspeisungen 45 . 46 and inductors 54 indicated arrows indicated.

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 move into the operating position shown in the figure via the belt 40 be driven.

Not just the inductors 54 are made compact in the direction of tape travel. There is also the space requirement of Induktorspeisungen 45 . 46 in the tape running direction of the tape 40 decreased because the two Induktorspeisungen 45 . 46 are arranged one above the other in the embodiment shown. Here is the rear inductor 54 with the upper inductor supply 45 , and the front inductor 54 with the lower inductor supply 46 connected. The inductors 54 are opposite the respective center of the Induktorspeisungen 45 . 46 shifted by a distance a, at about the same "footprint" of the device an adjacent arrangement of the inductors 54 to reach.

In this way, the space requirement is next to the tape 40 reduced in the range of rolling gears and / or rolling motors, not shown in the figure. The support elements or connecting elements of the individual Induktorpärchen 50 to the inductor feeds 45 . 46 are not shown in the figure.
