Abstract
Description
- The invention concerns a rolling mill for rolling metal strip, especially steel strip, which has at least one rolling stand, an upstream coiler, and a downstream coiler, wherein an “S” roll unit, which has two rolls that guide the strip in the form of an “S”, is arranged between the upstream coiler and the rolling stand and/or between the rolling stand and the downstream coiler.
- The increasing necessity for weight savings, especially in the automobile industry, has led to the development and use of load-adapted parts, so-called tailored blanks. The essential feature of these parts that is of special importance in this connection is that they have a variable thickness. Tailored blanks-were originally produced mainly by welding. However, it was found that they can also be produced in an especially favorable way by flexible cold rolling, which can be used to produce tailored blanks.
- In flexible cold rolling, the thickness of the rolling stock is varied during rolling. In this regard, the roll gap can be periodically varied. The thickness variation results in mass flow disturbances and tension fluctuations, especially on the entry side of the rolling stand but also on the delivery side of the rolling stand. At the rolling speeds necessary for profitable production, these mass flow disturbances and tension fluctuations can no longer be compensated by the dynamics of the coiler motors, so that so-called dancer rolls are used between the rolling stand and the coilers in installations of this type.
- WO 03/008,122 A1 describes a solution of this type. It discloses a cold rolling mill for cold rolling metal strip, which has a single stand with means for adjusting the roll gap, a coiler for uncoiling the strip upstream of the single cold rolling stand, and a coiler for coiling the strip downstream of the rolling stand. To achieve flexible rolling, a strip accumulator is arranged between the upstream coiler and the rolling stand for controlling the mass flow and the strip tension. This strip accumulator consists of at least three rolls. The middle roll is designed as a dancer roll and can be moved perpendicularly to the direction of conveyance of the strip.
-
EP 1 121 990 A2 discloses a similar solution—but with the use of a larger number of rolls. The same is true of a design disclosed by JP 10-034,204 A1. - The dancer rolls described in the cited documents are connected with a linear actuator, with which they can be moved perpendicularly to the direction of conveyance of the strip under open-loop or closed-loop control. The strip accumulator function that is essential for flexible cold rolling can be fulfilled in this way.
- DE 198 18 207 C2 and JP 60-231,516 disclose so-called loopers, i.e., rolls which are applied to the strip fed to the rolling stand or carried away from the rolling stand, in order, for example, to be able to undertake a determination of the tensile force in the strip.
- During rolling, the rolling force can be reduced by tensile forces on each side of the roll gap. However, it is only in the last pass that it must not be too high, since otherwise, as is known from experience, problems can arise in the subsequent process steps, especially during annealing. “S” roll units (“S” rolls) can be used to develop a tension difference between the rolling stand and coiler.
- When both a strip accumulator function is to be realized, generally with dancer rolls, and a desired tension difference between the rolling stand and the coiler is to be produced, generally by “S” roll units, considerable equipment expense is required in the prior-art solutions.
- Therefore, the objective of the invention is to modify a metal strip rolling mill of the aforementioned type in such a way that simple and thus economical means can be employed both to realize a strip accumulator function, especially in the case of flexible rolling, and to maintain a tension difference between the rolling stand and coilers that can be controlled in a well-defined way.
- In accordance with the invention, this objective is achieved by arranging a first roll of the “S” roll unit in a fixed manner and arranging a second roll of the “S” roll unit in such a way that it can move relative to the first roll.
- Apart from guide rolls for the strip that may additionally be present, only the “S” roll unit is intended, in accordance with the invention, to be provided between the coiler and rolling stand, but both the strip accumulator function can be provided and the required tension on the strip can be exerted with the proposed design of the “S” roll unit.
- In a preferred embodiment, the second roll, which can move relative to the first roll, is rotatably mounted on a swivel arm, which is supported at one end in a stationary axis. The two axes of the rolls of the “S” roll unit are arranged parallel to each other. It is advantageous for the stationary axis to coincide with the axis of rotation of the first roll.
- To swivel the second roll relative to the first roll, a linear actuator articulates with the swivel arm, preferably in a pivot some distance from the stationary axis. It is advantageous to use a hydraulic piston-cylinder system as the linear actuator.
- To be able to influence the development of tension in the strip in an optimum way, means can be provided for driving at least one of the rolls of the “S” roll unit.
- The proposal of the invention can be used to advantage in a cold rolling mill. In addition, the rolling stand is preferably a single stand. The proposed system is suitable especially for flexible rolling, which is why the rolling stand can have means for flexible adjustment of the roll gap.
- Finally, strip conveyance or handling is improved by equipping at least one of the coilers with means that allow rotational speed control.
- The proposed system makes it possible in a very simple and thus inexpensive way to provide a rolling plant for flexible rolling that makes available a strip accumulator, which is essential in this type of operation. In addition, the strip is also maintained at the required tension, so that the rolling itself can be carried out in an advantageous way from the standpoint of process engineering.
- A specific embodiment of the invention is illustrated in the drawings.
-
FIG. 1 shows a schematic side view of a rolling mill for the flexible rolling of metal strip. -
FIG. 2 shows an enlarged view of an “S” roll unit on the discharge side of the rolling mill. -
FIG. 1 shows a schematic view of a rolling mill, in which a coiledsteel strip 1 is uncoiled from anupstream coiler 3 and fed to a single cold rollingstand 2. Anothercoiler 4, which re-coils the rolledmetal strip 1, is installed downstream of therolling stand 2 in the direction of conveyance R of themetal strip 1. Thecoilers strip 1 can be uncoiled and coiled under open-loop or closed-loop control. - Flexible cold rolling of the strip is carried out in the
rolling stand 2. Thestrip 1 has a nonconstant thickness—as viewed in its longitudinal direction. This means that, during the rolling process, the roll gap is varied in accordance with a preset profile to produce a strip whose thickness varies periodically. - To allow this process to be carried out under conditions that are favorable from the standpoint of process engineering, it is necessary to compensate the change in mass flow in the strip that results from the variable strip thickness. Furthermore, a well-defined tension must be developed and maintained in the
strip 1 to keep the rolling force low. - To accomplish this, an “S”
roll unit upstream coiler 3 and therolling stand 2 and between therolling stand 2 and thedownstream coiler 4, respectively. Each “S” roll unit has tworolls strip 1 is guided in an S-shaped path. The resulting wrapping of therolls strip 1 and thus to maintain the desired tension in thestrip 1 between the “S”roll unit rolling stand 2. - To be able to achieve both the application of tension in the strip and the strip accumulator function, the “S”
roll units FIG. 2 . Each unit has one roll 9 (or 7) that feeds thestrip 1 to or guides it away from therolling stand 2. This roll 9 (or 7) is supported in a fixed position. By contrast, the other roll 10 (or 8), is movably supported and can swivel relative to thefirst roll 9, 7. To this end, it is mounted at the end of aswivel arm 11. The other end of theswivel arm 11 is supported in astationary axis 12, which coincides with the axis of rotation of thefirst roll 9, 7. - One end of a
linear actuator 14, which is realized as a hydraulic piston-cylinder system, articulates with the swivel arm, namely, in apivot 13 some distance from the axis of rotation of thesecond roll actuator 14 is supplied with hydraulic oil as indicated inFIG. 2 . - When the piston-
cylinder system 14 is acted upon by hydraulic oil under open-loop or closed-loop control, thepivot 13 can be raised or lowered, so that thesecond roll rotation 12. This results in a longer or shorter distance for thestrip 1 between therolling stand 2 andcoilers roll units - The above-described construction of the rolling mill and especially of the two “S”
roll units rolling stand 2 andcoilers linear actuator 14, it is possible to compensate the mass flow disturbances without any appreciable tension fluctuations. - To achieve this goal in the past, it was necessary to use a large number of rolls, which made these installations expensive.
- As a result of the compensation of the mass flow disturbances and the associated reduction of the tension fluctuations, the automatic control of strip thickness can be improved. It becomes possible to make adjustments of the tensile stresses favorable for the rolling process without regard to the tensile stresses present at the coilers.
- The compensation of the mass flow disturbances and the strip accumulator function are now realized in one piece of equipment, namely, the “S” roll unit described above, for which separate pieces of equipment were previously needed.
