Definitions
- the invention relates to a method and an apparatus for the continuous production of a thin metal strip, in particular a hot strip of steel, directly from a molten metal and with a strip casting thickness ⁇ 10 mm after a Walzeng screen processor using a Walzeng screen immunity, according to the preambles of independent claims 1 and 11.
- the invention relates to a method and apparatus for producing a hot rolled steel strip having a strip casting thickness ⁇ 6 mm.
- the hot strip thickness when storing the hot strip following the rolling deformation is between 0.3 and 4 mm.
- the proposed roll casting methods embodying the invention include all kinds of casting methods in which molten metal is solidified on the mantle surface of a casting roll and a metal strip is continuously formed.
- Both the single-roll casting process using a single roll caster and the vertical or horizontal two-roll casting process using a two-roll caster is suitable for the practice of the invention.
- the arrangement of the axes of the two co-operating casting rolls in a plane inclined at an angle to the horizontal plane is also suitable for implementing the method according to the invention.
- molten metal is introduced into a melting space laterally delimited by two rotating casting rolls and associated side plates, the axes of rotation of the casting rolls being substantially in a horizontal plane.
- the two casting rolls with the associated side plates including necessary adjusting and regulating devices in this case form the core component of the Zweiwalzengitinnate.
- the molten metal solidifies continuously on the lateral surfaces of the rotating, internally cooled casting rolls and forms strand shells, which are moved with the lateral surfaces. In the narrowest cross section between the two casting rolls, the two strand shells become at least one largely connected by solidified metal band.
- the cast metal strip is discharged at casting speed between the casting rolls and then fed to an inline thickness reduction in a rolling mill.
- the rolled hot strip is fed to a storage device and stored in this.
- This method is preferably suitable for the production of steel strip, but also metal strips of aluminum or an aluminum alloy can be produced in this way. Methods and systems of this kind are for example from the WO05 / 15233 , from the WO 01/94049 or from the WO 03/035291 already known in the main features.
- flat rolled hot-rolled strip In order to ensure perfect further processing, flat rolled hot-rolled strip must comply with flatness tolerances, some of which are defined in standards or demanded by customers according to the intended further processing. Experience in the production of hot rolled steel strip has shown that it is very difficult to meet these requirements when using the two-roll casting process on a corresponding casting plant.
- the metal strip is produced in a process of highest solidification rates directly in a format with extreme width / thickness ratio, which accounts for a variety of rolling passes to achieve the desired hot strip final thickness, but on the other hand, a wide independent, uniform convective heat transfer or liquid metal temperature at the solidification front (in the formation of the strand shells) are only partially possible as a result of highly turbulent flow processes in the metal bath.
- the in-line rolling of a cast metal strip can also contribute to the formation of further unevenness when the strip inlet temperature (inlet temperature of the metal strip into the rolling stand) over the width of the metal strip is relatively non-uniform, or the inlet strip profile is unknown or changing. This results in a variable forming behavior in the roll gap by different springing or nip profiles transverse to the rolling direction.
- the cast metal strip has on entry into a rolling mill an entrance structure with a cast structure, which is converted with a small decrease in a fine-grained rolling structure in order to achieve favorable material properties for the respective further processing steps.
- the input thickness in front of the rolling stand is less than 10 mm, preferably less than 6 mm.
- the high roughness of the metal strip caused by the casting process and by possible scaling, leads to a high work roll wear. These signs of wear on the work rolls increasingly occur in the strip edge area and lead to errors in the strip profile.
- the wear phenomena are greatly influenced by the strip material, the strip profile and the thermal profile.
- the object of the present invention is therefore to avoid these disadvantages and to propose a method and a device with which it is possible, in a continuous production process, starting directly from molten metal and a strip casting thickness of less than 10 mm, to produce a high quality, hot-rolled metal strip produce with a comparable property profile, in particular with regard to the desired flatness tolerances, as currently in the production of hot-rolled metal strip, especially steel strip, continuously cast thin slabs or slabs, with casting thicknesses between 40 and 300 mm, can be achieved with the prior art rolling devices.
- This object is achieved in a method of the type described above in that a flatness measurement is performed on the moving metal strip and the flatness measured values of this flatness measurement are used for selectively influencing the flatness of the metal strip, that the inline thickness reduction of the metal strip in at least one deformation stage in an at least the flatness measurement is carried out before or after at least one deformation stage, wherein the flatness measurement is carried out by determining the stress distribution in the metal strip in a transverse plane to the transport direction.
- the influence of the flatness of the metal strip can be done either during the metal band formation between the lateral surfaces of the two casting rolls or during inline thickness reduction via a control loop, but also by manual intervention.
- the flatness measurement takes place along the path between the roller casting device formed by at least one casting roller and the storage device, in a plane transverse to the direction of strip travel.
- the flatness measured values of the flatness measurement are used to influence the surface profile of the casting roll, wherein both the profile formation during the casting process in the two-roll casting device and the profile formation or change during the first roll pass in the first rolling stand are monitored and influenced.
- the inline thickness reduction of the metal strip takes place in at least one deformation stage in an at least stand-alone rolling mill and the flatness measurement is carried out before or after at least one of these deformation stages, preferably immediately after the first deformation stage.
- the measured values of the flatness measurement are used to influence the roll gap in at least one roll stand of the rolling mill.
- the measured and optionally processed in a central processing unit flatness values are used for a "closed loop flatness control", wherein components of the rolling stand, or the rolling stand largely immediately upstream facilities for the roll gap influencing or for influencing state variables of the metal strip are used.
- the measured values from the flatness measurement can be used for an at least zone-wise thermal influence of the metal strip.
- a further improvement of the flatness tolerances on the produced hot strip is achieved by determining a temperature profile of the metal strip in a plane transverse to the transport direction of the metal strip, at least before or after the rolling mill, and using the measured temperature profile for selectively influencing the flatness of the hot strip becomes.
- Local temperature deviations of the hot strip which occur longitudinally zone by zone, can be specifically influenced if the temperature distribution in the metal strip is influenced in sections in a plane transverse to the transport direction of the metal strip depending on the measured temperature profile.
- strip thickness profile is measured in a plane transverse to the transport direction of the metal strip and the measured strip thickness profile is used for selectively influencing the flatness of the hot strip.
- the invention is preferably used in the production of a metal strip by the two-roll casting process, in particular the vertical two-roll casting process, wherein a flatness measuring device for measuring flatness measured values of the metal strip is arranged between the roll casting device and the storage device and the flatness measuring device is assigned an evaluation device for detecting and converting the determined flatness measured values is.

- the flatness measuring device is arranged before or preferably after the first rolling stand.
- the flatness measurement can be carried out with various flatness measuring devices available on the market. In most cases, such measuring devices are known for determining flatness values from cold strip production, so that corresponding adaptations with regard to temperature resistance and measurement accuracy at high temperatures are necessary for the special application with hot strip at rolling temperature.
- the flatness measuring device is preferably formed by a flatness measuring roll, a device for optical design detection or a device for detecting other inhomogeneities of strip surface properties.
- the metal strip is usually under strip tension, which is taken into account in the evaluation of the measurement results in the evaluation. With an optical design detection of the metal strip, the metal strip must not be under strip tension, in order to achieve good measurement results.
