Definitions
- the present invention relates to a rolling method for a metal strip with a metal strip width, the metal strip being rolled in at least one roll stand, an amount of lubricant being applied to the metal strip distributed over the metal strip width, and to a corresponding roller arrangement.
- Such rolling processes and arrangements are generally known.
- the object of the present invention is to provide a rolling method and a corresponding roller arrangement, by means of which even more even, more even strips can be produced.
- the object is achieved for the rolling process in that a lubrication curve is determined behind the roll stand over the metal strip width and used to adjust the amount and / or the distribution of the lubricant and / or at least one rolling parameter.
- a lubrication profile detection device for determining a lubrication profile over the metal strip width is arranged downstream of the roll stand in the rolling arrangement.
- the lubrication distribution can be determined directly or indirectly.
- the metal strip behind the roll stand has a temperature profile over the metal strip width.
- This temperature profile can be recorded - for example by means of an infrared or CCD camera - and the lubrication profile can then (indirectly) be determined from the temperature profile.
- the lubrication process can directly.
- B. can be determined based on a surface texture of the metal strip behind the roll stand.
- the surface quality of the metal strip can, for example, be optically recorded on one or both sides of the strip.
- information about the lubrication process is output to an operator for the roll stand and for the operator to adjust the amount and / or the distribution of the lubricant and / or the at least one rolling parameter.
- the rolling process works more comfortably if the information about the lubrication process is output to a controller and the controller adjusts the amount and / or the distribution of the lubricant and / or the at least one rolling parameter.
- the lubrication conditions are preferably only influenced locally. This is usually done by changing the deficiencies and / or the distribution of the lubricant.
- systematic lack of lubrication e.g. B. Lack of lubrication at both ends of the tape across the metal bandwidth, z. B. influence on the roll bending of the work roll.
- other rolling parameters can also be influenced.
- the change in the amount and distribution of the lubricant can e.g. B.
- the lubricating device has a basic lubrication device and an additional lubrication device and the amount and distribution of the lubricant to be applied by the basic lubrication device is constant and the amount and / or the distribution of the lubricant to be applied by the additional lubrication device is adjustable.
- the rolling plan computer gradually learns which lubricant quantities and distributions for certain Metal straps or pass schedules are required.
- the metal strip can consist of various metals, for example steel, copper, aluminum or brass.
- Figure 2 shows a temperature profile
- Figure 3 shows a rolling arrangement from the side.
- a metal strip 1 is rolled in a roll stand 2 with work rolls 3 at a rolling speed v.
- the roll stand 2 is according to FIG. 1 designed as a two-roll mill stand. So it only has the work rolls 3.
- the roll stand 2 could also have backup rolls, possibly also intermediate rolls, shifting systems in one or more of the roll planes, etc. or z. B. be designed as a so-called twenty-roll mill stand.
- the metal strip 1 has a metal strip width b.
- the metal strip 1 consists of steel. But it could also be made of another metal, e.g. B. copper, aluminum or brass.
- a lubrication device 4 is assigned to the roll stand 2. According to Figure 1, it is arranged in front of the roll stand 2. By means of the lubrication device 4, an amount of lubricant 5 (for example an oil-water mixture) is applied to the metal strip 1 from above and below over the metal strip width b.
- the lubrication device 4 has a basic lubrication device 4 ′ and an additional lubrication device 4 ′′.
- the amount and the distribution of the lubricant 5 to be applied by the basic lubrication device 4 ′ is constant - at least during one puncture.
- the amount and / or the distribution of that from the additional lubrication device 4 "Lubricant 5 to be applied is adjustable.
- the metal strip 1 has a temperature profile behind the roll stand 2 over the metal strip width b.
- a temperature profile detection device 6 is therefore arranged downstream of the roll stand 2.
- the temperature profile detection device 6 is designed, for example, as an infrared camera.
- the temperature profile of the metal strip 1 behind the roll stand 2 is recorded cyclically over the metal strip width b by means of the temperature profile detection device 6.
- the lubrication curve is then determined from the temperature curve or inferred about possible stability problems in the roll gap.
- the tem- Temperature course detection device 6 thus serves as a lubrication course detection device 6.
- the temperature profile detection device 6 can be designed in various ways. Instead of an infrared camera, for example, a CCD camera or a sensor array can also be used. In any case, however, the temperature profile detection device 6 should be arranged as close as possible to the roll stand 2. The distance should be a maximum of 5 m to 10 m.
- the lubrication course detection device 6 is connected to a controller 7.
- the controller 7 is in turn connected to the lubrication device 4 and / or the roll stand 2 for control purposes. Based on the detected temperature or lubrication curve, the controller 7 can thus adjust the amount and / or the distribution of the lubricant 5 and / or at least one rolling parameter, eg. B. the rolling speed v, make.
- the lubrication course detection device 6 is also connected to a rolling schedule computer 8 via the controller 7.
- the rolling plan computer 8 is superior to the controller 7.
- An adaptive rolling model is implemented in it.
- the adjustment of the amount and / or the distribution of the lubricant 5 and / or at least one rolling parameter, e.g. B. the rolling speed v, are also transmitted to the rolling schedule computer 8.
- the rolling plan computer 8 is thereby able to adapt the rolling model implemented in it, so that better presettings can be made for a new metal strip 1 to be rolled.
- the lubrication course detection device 6 is also connected to an output device 9.
- the output device 9 is, for example, a monitor via which information about the lubrication process is output to an operator 10 for the roll stand 2.
- FIG. 2 shows three different temperature profiles A, B, C that are standardized to the minimum temperature across the metal bandwidth b. Furthermore, a line is drawn in broken lines, which corresponds to a temperature which is above the minimum temperature by a predetermined percentage. The percentage is typically between 5% and 10%.
- the additional lubrication device 4 is activated locally, in particular to increase the amount of lubricant 5 to be applied in this area.
- FIG. 3 essentially corresponds to FIG. 1. It can be seen particularly clearly from FIG. 3 that the lubricant 5 is applied to the metal strip 1 both from above and from below. In contrast to the exemplary embodiment according to FIG. 1, there is no controller 7. The setting of the amount and / or the distribution of the lubricant and / or the at least one rolling parameter is therefore carried out by the operator 10 according to FIG. 3. Controlled lubrication in the roll gap can be achieved for the first time with the rolling method according to the invention or the corresponding rolling arrangement. This leads to a higher stability, an optimized quantity and distribution of lubricant, a planer metal strip 1 and a reduced slipping.
- the rolling process can be used in all rolling processes. However, it is used particularly advantageously when the metal strip 1 is cold rolled, that is to say the rolling arrangement is designed as a cold rolling arrangement.
